What oil in the AL4 automatic transmission. Rules of operation automatic transmission AL4

If timely produce all engineering works On any car, including Peugeot 308, then this can significantly increase its life. This is especially true of machines with automatic transmission. This can be installed on Peugeot 308.

Problems with such an aggregate are mainly arising due to the fact that it is incorrectly careful. Here is a mandatory moment is the timely oil change. How to pursue such a procedure as well, which oil is poured, it will be written in the article below.

The manufacturer says that the replacement of lubrication in the automatic transmission at the 308th must be carried out after a run of 100,000 kilometers. Also, such a procedure can be done before. Here everything will depend on the conditions of operation of transport and the desire of the owner itself.

If there is no desire to repair the box through 60,000 mileage kilometers, then the oil is recommended to change it in 30,000 kilometers.

Replacing lubricant in the transmission may be full or partial . Constantly full replacement You can not fulfill. To work properly for a long time, you can simply regularly make partial oil replacement in it.

What to pour?

Oil for automatic transmission Mobil ATF LT71141.

For automatic transmission it is impossible to use the oil that is poured into the manual transmission.

For automatic boxes there are special fluids that can perform such functions.:

Distill heat from frictional.
Guarantee the operation of the hydrotransformer.
Delete from box wear products.
Lubricate details that are drunk among themselves.
Used control system.

Currently there are three classes of oil for automatic transmission:

Synthetic.
Mineral.
Semi-synthetic.

All of them differ among themselves with their composition, as well as a type of additives.

ATF LT 71141 standard oil.

Fixtures

For carrying out lubrication replacement activities, such a tool and consumables should be prepared.:

Funnel for draining liquid from the box.
Keys (dynamometric).
Rags.
Butter.

The amount of oil in the Pengeon 308 - 7 liters. With partial replacement, it is recommended to drain three liters of spent material.

Should change oil by 3 l. through every 30 000 kilometers of way.

With partial replacement it is necessary to buy 3-4 liters of oil, and with a complete - 9 liters.

Algorithm for replacing oil in automatic transmission on Peugeot 308

The car should be driven into the lift.
We drive the car on the lift or flight.
Warm motor. For this you can drive 2-3 kilometers or give the car to work on idling 5-10 minutes .
Remove Carter Protection.
Remove the crankcase protection.
Unscrew the plug for draining the liquid by a four-brand.
Using a tetrahedron, unscrew the cork for draining the liquid.
Under the drain hole, put the tank for draining the liquid.
Drop the lubricant from the box by unscrewing the plug.
We unscrew the internal cork.
Remove the plugs for draining the liquid, replacing gaskets in them. They are twisted without much effort.
Do this follows a torque wrench with effort in 2.2.-2.5 N / m .

Raise the hood.
Raise the hood.

Remove the air filter element.
We dismantle the air filter.

Unscrew the terminal "+" on.
We dismantle the positive battery terminal.

Unscrew the terminal "-".
We unscrew the minus battery terminal.

Remove the battery by unscrewing the key to the key to "10".
I unscrew the battery mount to 10.

Unscrew the cork for the oil bay and pour fresh liquid. A drain plug should be twisted. For the pouring you can use a funnel.
We unscrew the filler cork using the square.

Pour oil.

Split a plug with a torque wrench. Effort - 3.2 nm. Also on the traffic jam you should replace the gasket.

Put in place the battery.

Start the engine and give it to work 5-10 minutes At idle.

Then the speed switch lever must be translated into all the provisions and put it again on "P".

In order for the oil level to be determined correctly, the car initially need to put on a flat pad.

findings

As can be seen from the process described above, with work on the replacement of oil in automatic transmission on Peugeot 308 can be performed on its own.

(Automatic transmission)

ATTENTION : Drain from automatic transmission must be performed with hot oil (at least 60 ° C) to remove dirt in suspension oil.
To replace oil in the automatic transmission, you will need an overpass, car lift or a pit, to remove the protection of the crankcase and unscrewing the drain plug, on some models, the Peugeot is not required, since special holes are made in the protection of the boat, it may not be necessary, but the drain plug will have to unscrew in any case.
The main plug for level check
Cork, oil plum tube

The volume of the fluid fused in the automatic transmission is approximately 3 liters.
To unscrew the main traffic jam on automatic transmission (in photo №1)it will take a knob or a square with a square cross section as shown in the photo.
The next step is to replace, you need to unscrew the tube - the tube for the main plum of three liters, it is unscrewed by a hex manner for eight.
NOTE : Replacement is partially produced, it is impossible to completely drain the oil from the torque converter.

When all oil glass, set:
Cork plug and oil filling (2); Tighten the moment 0.9 ± 0.1 days
Level check plug (1); Tighten the moment 3.3 ± 0.5 days

NOTE : Volume of fusion working fluid The automatic transmission should be approximately 3 liters.

Installing the Carter protection is not hurry, as it is necessary to control the oil level in the automatic transmission after the bay.
ATTENTION : Allowed to use only ESSO LT 71141 oil.

Filling capacity dry automatic transmission: 5.85 liters.
Volume of working fluid for fill: approximately 3 liters.
Tighten the plug in automatic transmission (3) (preferably with a new gasket); Tighten the moment 2.4 ± 0.3 days.
Reset the working fluid wear counter (follow the procedure specified in the diagnostic computer).

Checking the oil level in (Automatic transmission)
Prerequisites:
Auto must be on the horizontal plane
There is no displeasement of automatic transmission
Unscrew the tube of the bay of the working fluid (3) photo
Pour floor-liter oil
Press the brake and switch the ACP selector several times
Set the selector to parking
With the engine running at idle, unscrew the plug (1)
Heat the car and automatic transmission 60 ° C (+ 8 ° C; -2 ° C)
Wait while working fluid does not flow with air bubbles

NOTE : The oil level in the automatic transmission is achieved by draining the oil on the engine running, first the trickle, then the jet with air bubbles, then drops, usually twist the tube when the working fluid merges with air bubbles

Increased fluid level can cause oil overheating and automatic transmission
Low level, the friction rates will wear
Do not pour any washing fluids at Automatic box Al4 gear!
A few more general words about replacing oil in automatic transmission
For each car owner, an integral process is to replace the oil in the gearbox. Such an action must be performed regularly and exclusively by professionals. Attempts self-decide This issue can significantly harm the gearbox functionality. To date, there are only two main types of oil replacement: partial and complete.
The process of partial replacement of oil in automatic transmission
After the arrival of the car for a hundred, the old liquid from the transmission pallet merges. After this action, the pallet is removed and the filter part. These components are subjected to detailed car wash and cleaning. After completion, they are installed back in place. It should be noted that you need to update the pallet laying and filter. Then the new oil is poured, and the workers of the service station are exposed to the desired level. The car is settled, and tosses to the lower level begins. A small minus of such a way is that the old and new option is mixed. All sediments from the working fluid remain inside the aggregate. That is why it is possible and not to notice any special changes in the operation of the automatic transmission.
Full replacement of fluid in automatic transmission
Under the action of full update, impress the exhaust oil from the aggregate. But its full of it is 100% cannot be called. The thing is that some remains. On average, it is about 0.5-1% of the total volume. Each transmission includes a cooling system in its structure. She goes beyond the box. It takes continuous circulation of fluid when the car engine is in working condition. Only modern equipment can solve the problem of removing the exhaust material from the system. But the same device takes part in pumping the new fluid.
He takes the old and immediately fills the chain of a new one. Control of the operation of the equipment is carried out by a service station specialist who monitors dashboard. The device must consist of two transparent tubes. They are intended for pumping and allow you to visually assess the overall condition of the driving oil. And only after. As the color in both tubes will become the same, the process can be considered completed. If you use a complete replacement, and not partial, then the driver gets:
Improved automatic transmission
Economic savings (with partly, replacement should be carried out every 10-20 thousand km.)
Save personal time
Box functionality pulling

Replacing oil in automatic transmission should be carried out exclusively by professionals.
Causes of oil leakage from automatic transmission
Auto Masters soviet era They joked that if the car does not eat oil, it means that it ended there. Now the situation has changed, the configuration of cars is constantly complicated. It was even important that it was exactly what kind of oil you are pouring in the box, but about his absence, no one speaks even a joke, understanding what it can lead to.

Of course, if in the morning in the morning of your car, you found a suspicious oil stain, this is not a reason to immediately call the tow truck and drive the car to the service. But check out your suspicions. To do this, on the evening, put the car into the garage, pre-laying under the automatic transmission several sheets of paper or newspapers, on which there will be a clearly visible droplets of the oil. No garage? Not a problem. Just try to choose a clean dry place with a solid coating and without strangers. In the morning we will look at the result. If there are stains of oil, the case is in the gearbox of your car. It cannot be left without attention, especially since the oil is at resting the oil has a greater viscosity. If it drips on a cold box, then while driving, when the oil begins to heat up, its turnover increases, and flow is enhanced.
Where simple
First you just remember whether any work has been done with your box lately. After all, the working fluid can be reduced due to the usual slide of the one who produced them. The reasons may be the following manifestations:
drain oil plug is not tightened, which is not a rare phenomenon;
not twisted to the end sensor rear stroke After replacing it, even worse, if it is not twisted on the thread;
creation or loosely inserted probe, which measure the level in the box;
banal overflow liquid in the box.

There is an erroneous opinion that the box does not spoil the butter. This is not true. With an excess, it will be squeezed. At the same time, the oil seals may be damaged. All this can be very easy to solve with tools and their hands. We heat the car on the pit or the overpass to be able to free access to this unit. The most important thing is to do everything without fanatism, so as not to thwart the thread on the drain traffic.
A little harder if the oil leaks through the gasket. Also, it is also possible to easily at a hundred. You just need to buy a new gasket. When replacing the place of its installation is checked for scratches or chips. If they are presented, the surfaces of the surface restore the usual epoxy resin and set the gasket to a special sealant.
Breather
When the car moves, the oil is heated when it is worth it. To compensate for the pressure drops resulting from this, such tubes are installed on the caps of the gearboxes, through which the gas during its expansion is fluent in the atmosphere. If this tube is clogged, then the pressure begins to rise inside the box, and the oil begins to pushed through the glands.
The problem of simple cleaning of the Sapuna is solved. To do this, we immediately buy a new gasket under the lid. It is not recommended to use old. Remove this cover and wire or steel cable of the corresponding diameter clean the Sapun. After that, to remove the remnants of the contamination, blow it and rinse with gasoline. On some models, the PPC Sapun is an oiled valve. It is inexpensive, so it is more expedient to replace it.
Stuffing box
For various reasons, including if you do not clean the Sapun, and simply due to wear, the oil can flow through the glands. If all is a matter of the age of the gland, then just change it and go. If the gland fails on a relatively new car, then it is worth finding out the reason for this phenomenon. It is possible that recently you used low-quality oil.
Replace the glands without sufficient skills for this, it is better not to produce on their own. It can be damaged during installation or put with a breakdown. In any case, as a result of this repair, the oil can flow even stronger.
The most unpleasant in the automatic
If the oil flows through the seal on the drive, you can only remove the cause of the transmission. Usually in such cases, car owners are at the same time trying to immediately replace the clutch, make the full diagnosis of all working mechanisms of the box and, of course, replace the gasket.
If the oil drips or flows between the engine and the box, then on imported cars it may mean a damage of the torque converter. Accordingly, it is necessary to have the nearest repairs, especially this defect is characteristic of the Japanese assembly.

In any case, it is impossible to obnimally watch how the oil leaves the automatic transmission of your car, it can lead not only to expensive repair, but also to creating you emergency situation, especially if the box is jamming while driving a car.
How to check the oil level in the automatic transmission - tips and recommendations
How to change the oil in the engine with your own hands All about the variator on Peugeot Automobile Peugeot, Device Box Machine Al4

French automaker PSA (Peugeot Citroen Association) together with Renault, launched this 4-step in series automatic transmission DP0. (she is - Al4.) in 1999.

ACAP AL4 is designed for front drive and engines from 1.4 to 2 liters. There are a large number of options for drive gears and housings. Designers argue that DP0 can transmit torque to 210 nm. But the manufacturers were forced to "fasten" settings, without bringing the transmitted torque to the limit so as not to allow the owner to kill the back cover and ensure mileage to overhaul over 150-200 TCM.

Automatic Al4-DP0. It is a unique and pretty successful development of French engineers. Its design is ingenious simple and very rational: "nothing superfluous."And as a result, it has a low cost.These advantages helped to sell more than 1 million machines with a DP machine and at the same time created headache (Pleasant, perjudity box) for automatic transmission masters.

Although the manufacturer "Peugeot Citroen" calls her " Al4.", in Russia it knows how DP0. By classification Renault.whose cars were the first to come to the overhaul automatic transmission.

In 2013, on the basis of DP0, the French for Russia, new modifications of AL4 adaptive automatic transmission were issued for Russia (with the Tiptronic System Porsche system), which has not changed hard. Renault calls these two modifications: DP2. - for front-wheel drive cars and DP8. - for all-wheel drive. They updated an electrician, the operation of the hydrotransformer was changed, which is already turned on at first speed, and at the same time, the ZF has already made, it serves relatively long and reliably. Remkomplekt DP0 consumables are suitable for DP8. Almost completely, while only there is no new seal for the right half.

It is believed that the AL4 transmission itself is easily running to 200 tkm, and with normal operation and timely maintenance / overhaul and up to a million.

Cooling automatic transmission

DP0 has a heat exchanger for cooling oil. All heat exchanger transmissions work in temperature mode Close to critical. In the summer of automatic transmission DP0.regularly overheats, the electrician suffers, namely the hydraulicock. Such. constructive feature Many automatic transmission with heat exchanger. The duty after runs for 80-100 TCM lies on the owner.

It should be borne in mind that at the operating temperature +75 .. + 90 ° DP0 is almost eternal. The more load it at low and too high temperatures, the earlier the premature old age of elements is coming. In addition, programmers allowed gas supplied to the floor with the 2nd speed to include mode forced lock Couplings, which reduces heating, but accelerates oil pollution and wear.

Frictions pollute the oil, dirt settles in the heat exchanger, (which also works as a filter) and as a result, after critical pollution of the heat exchanger, the oil in the heat does not have time to cool. Why hydrophlitis (and solenoids) cease to work normally. And than dirty oil, the higher working temperature And the worse controls the switches of hydroblock speeds.

The heat exchanger is not accepted due to its too high price and short reserve on the resource. It is washed with large quantities of cheap oil ATF. (internal) and antifreeze - external contour. But it is easier and more efficient to embed additional cooling instead of the tired heat exchanger slaughtered by resins. Most masters prefer to install the radiator along with.

Developed -Adapters for the installation of the radiatorleft 144998 instead heat exchanger DP0. An external ATF cooling and thermostat 100099 are already connected to the adapter.

With overhaul, the age automatic transmission masters usually change the heat exchanger to the outer radiator. But all these troubles are justified if the owner plans to exploit its car for another 2-3 summer.

Replacing oil and filter

Oil on which this box of 20th century is designed - Quality DEXRON-III. Esso and Mobile Analogs 71141 work well in this box. Renomatics option - D3 SYN. Oils require about 7 liters. For replacement, grabs 3.5 - 4 liters.

The level is checked and exhibited by overflow plug. First Z.oil (0.5l) is alive through the bay hole (1) before checking the oil level. Level Checked at o approx. 60 ° C with the engine head and the position of the lever in "P". It should pour the oil approximately equal to the flooded and on the leaving the oil is checked it.

Oil filter automatic transmission for all models is the same - No. 144010. Metal plastic filter thin cleaning It has a felt bag and requires replacement every ... however, the automatic transmission experts exist opposite opinions about changing the oil and filter DP0: from "non-changeable oil" to "change every 20 thousand km."As one rabbi judged: ".. and you are right, Moisha, and you, Semyon."

The fact is that while the car is new, all articulations and nodes have factory gaps, sleeves are constantly, the oil is quite reliably cleaned by the filter. And up to 80-90 TCM runs the filter rarely requires replacement. Under the condition of competent and gentle and absence of emergency overheating or overload. And regular checks during this period show that the oil is still quite transparent.

But as aging and wear and the accumulation of dirt in the oil begins a chain wear reaction with oil pressure loss. The pump lists more and more oil, but everything comes to packages less pressure And dirty oil is fistilized through the slots of seals and the sleeves all more intense. And after 150-200 TCM really needed or change the oil ("partial" replacement) every 20 TCM, and it is necessary - a regulatory overhaul of the box and a torque converter is required. Well, or change the machine to the new one.

Than older aggregateThe greater the wear of the "iron" nodes and the faster oil pollutes in it.

The resource of this automatic transmission to overhaul with a neat and properly operation It can be 150-200 TCM, and after timely repairs with full bulkhead and replacement of consumables can be extended to half a million if the machine itself is still on the go.

At the same time, the overhaul should be decided, without waiting when the car refuses to go and request a "dying pit."

Details for bulkhead and overhaul

Choose repair kits - press the left key.

For the complete bulkhead of the age car usually ordered all sets of consumables (components of the workshop), a set of pistons, sleeves, brake ribbon, filter and EPC \\ TCC solenoids.

Kits (Repkkomplekt "Overol") - №144002 - suitable for all French cars. The two most popular configuration masters are more complete and popular (- 144002a -pr) andmore budget - - 144002D). Both of these overol contain the gasket of the hydroblock.

Remkomplekt DP0 fitsfor DP8 / DP2. Almost completely, so far only in them there is no groove of the right half.

Repair kits for full bulkhead boxes are ordered almost always together with complete set friction discs - № 144005 - frictional, equally ordered non-original and original from the company. The ratio of price \\ quality is equivalent. Also suitable for DP8 \\ DP2.

A set of rubber pistons enters almost every order to overheated box overheated. The masters decided on the choice of quality and configuration (with the piston of servo) of this kit - №144008B-NK. ()

Since 2004, the hydraulicock has changed and put the hydraulic block laying (enters the Overolkit of the SCT and the presskin), the old masters are rarely changed, sometimes not even knowing that it is. Together with it, Teflon rings with 3D cut are required for the E1 package.

Full Remkomplekt Masterkit - 144007 includes a set of gaskets (002) and friction (005).

The bulkhead is necessarily made with the repair of the hydrotransformer -144001 .

Weak spots ACP AL4-DP0 by electrical part: Solenoid ( ) - Pressure electric motor 144431 . Replace leader. Plastic sealing rings are always changing with them (144179) and the sleeve - the reason for the rapid production of solenoid resources. According to the manufacturer, the solenoids of release until the fall of 2003 have constructive flaws and are required for replacement at the first automatic transmission. After replacement requires an automatic transmission adaptation. Both solenoids are usually changed (EPC linear pressure and TCC-locking of the hydrotransformer). There are "original" solenoids and solenoids Borg Warner. In the boxes with the "original" solenoids have long been already put by the solenoids of the American manufacturer of the original Borg Vorner, refusing their own production of these complex electroclapanes. But the price of the "original" is usually slightly higher. EPC solenoid resources are relatively small, especially if the knots of the box (Teflon rings and sleeves) are worn. The first EPC solenoid is common, but the unauthorized work of the second solenoid (TCC) is very quickly overheating and pollutes the oil, killing the hydraulicock. If you do not replace the sleeves and teflon rings, then the replaced solenoids live long. The remaining 6 solenoid-encryption EVS -№144421 Work without overloads and change them infrequently.
Sleeve. Cylindrical sliding bearings (so theorists call ordinary bushings) The role of seals are also performed here. And the first to popularity is the wear of the sleeves. The border wear leads to a chain reaction: they begin to skip oil, there are not enough pressure in packages and the computer makes the ERS solenoid open the channel for a complete section, the pump operates at the maximum load and the ERS solenoid begins to be accelerated. Working with the lack of pressure "kills" the frictions of the appropriate package and oil. When bulkheads check the state of the sleeves, and when the solenoid is replaced, the most stressful sleeves are checked (- 0.100 mm): Pump cover sleeve, DP0 / AL-4 (57.2X 54,8mm x13,7mm), usually order Sonnaks bushings144034 , - Pump rear stator stator bushing (29x 26.0 mmx16) -# 144037 and the sleeve of the drum E2 / E1 (37.9x 35.2 mm x17) 144036. If the wear exceeds the tolerance of all 3rd bushings, then the sleeves change the sleeve with all 144030. The Masters specializing in the DP0-AL4 have a special tool \\ "caliber" to check the wear of all 3 sleeves. After installing Sonnaksov's sleeves, DP0 walks for several more years when compliance with the purity and temperature of the oil. At the same time make sure pilotransformer overhaul - 144001 .
From loss of oil through worn joints drops pressure in the line and surround and burn friction. Depreciation of unilateral friction disks occurs evenly and friction discs change in almost all overhauls complete set: № 144005. When selling friction discs separately, the cost of the entire set is obtained above. More often buy a set Borgvorner, in 30% of cases - neoriginal. DP0, which has worked out several hours with burner oil, requires replacement of frictional friction (+ friction-converter friction + brake tape) as a regulatory work with the replacement of solenoid pairs. This is especially important if the friction linings are impregnated with ground oil resins, after which they significantly reduce their abilities to remove heat and keep the load until the "breakdown to slip", which leads to shocks and slippages.
When repairing superheated automatic transmission, all rubberized pistons change with a complete set, despite their condition- Piston set (7 pcs) -144008 . Basically - Taiwanese neoriginal of verified quality 144008B-NK. You can not change all the pistons if you have great experience Defecting and replacing pistons in this transmission. Pistons 144902 (servo F1) and 144912 (servo F2) are the first to produce a resource. Without their replacement, brake tapes clinches and burn already in the first weeks of operation after the overhaul.
- Brake ribbons (pair F2 and F3) - # 144020,which change at each overhaul of the automaton who came with burnt oil. With them together change and pistons servo (above). Brake ribbons are mostly taken non-original. But every tenth order is the original from Borg Vorner, ordered mostly novice masters and owners for the safety net. Long-term riding with a worn tape and servant leads to the fact that it is necessary to change and the extension drum package F3 - №144550.
Hydraulic valve block (hydroblock) # 144740 - the usual repair place. It categorically does not like overheating and dirty oil. From overheating, the metal plate changes geometry, spools climb and the springs are overloaded up to breakage. One of the old-age substitutions is the oil pressure sensor: No. 144415. With the local repair of the hydraulic block on the age-related car, the laying of the hydraulic lid changes - 144301. There were several modifications of hydroblocks for different engines and cars. Due to overheating, the aluminum alloy of many hydroblocks is corrosive. Often, the stove channels are clogged with a chips and a slust from the friction paper, which leads to abnormal operation of the hydroplate. With overhaul, it is necessary to check the geometry of the case. The valve blocks of releases of 2008-11 often dismissed the bolts of fastening the upper plate. The resource of the hydroblock is significantly reduced during operation with dirty oil. Silence of friction dust is abrase of channels and valve spools. The American Sonnax Repair Guru released Repair Kit for "Aorto-Coronary Shunting" of Worn DP0 Hydroplits, but rarely who are solved on such a complex operation when the new plate is not much more expensive and gives a guaranteed result. Although the hydraulicock is so reliable and maintained that rarely when the overhaul requires replacing the valve plate itself. In most cases, the cleaning and replacement of EPC \\ TCC solenoids is sufficient.
Teflon rings of the back cover of the wizard are recommended to change with each disassembly:- Compression Ring Small (32x1.9x28) and Ring compression large back cover, 2 pcs. (54x1.9x50) # 144179. (included in Remkomplekt 144002). Always replaces the gasket when local repairs back cover - 144304 . Rings set - 144199. Worn due to operation with dirty oil, aggressive acceleration or long slip in snow or dirt. (Worn GDT coupling) leads to loss of oil pressure and clutch and friction combustion.
- One of the frequent diseases of "iron" - Needle bearing - №144231. It is between hub 570 and a 554 drum in E2 package. Each time the dp0-Al4 bulkhead is the wizard, it is recommended to check this place.
The leader in replacement among the glands and seals is the broken cuff (seal) of the pump 144070. ( pass in Remkomplekt. 144002 ) But almost always change the rest of the glands: - Semi-axes left # 144076, and outdoor right from the corps side. # 144077 Change of these salts experienced masters It always happens, whether Overoll whale was bought (Remkomplekt gaskets and glands) or not. It is worth keeping in mind that oil leakage is not treated alone alone only. This is a symptom of a more serious problem and if you do not check the wear of the bushings and work underwater transformer, The cheap replacement of the gland usually simply kills the pump, bushings and the rest of the "iron" transmission.
If the problem with the underlying sunel in the pump and sleeves is launched, then you have to change the entire pump - 144500. Almost always for repair is used by the pump.
Next - Rare Replacements of "Iron" on the corrugated age-related machines: Planetary series, rear - REAR, №144582 . Coupling drum F3 - 144550.

Inter-cruise gaskets have two types: on a car with an engine of 1.4-1.6 liters and from 1.8-2.0 liters. They differ in size (10 mm long)144305

From consumables leader in replacement is the clutch package E2 (4th).

Friction discs package E2., DP0 / AL-4, unilateral with inner teeth (№144100BI)and adjacent to it - one-sided with outdoor tooth (№144120BE. ) Change every time repairs.

Also often burn 144106 144126 package F1. And frictions with disks 144110 144130 package E1. With the replacement of frictional, the corresponding sleeves and rings are changed.

Differential - 144716. (Different on the slots on the shaft for Peugeot and Renault)

The box is very simple and maintainable. Spare parts are easily accessible on the first call. It was trained and hundreds of beginner inspection masters of automatic transmission. And if the repair is competent, then it passes not yet one summer. No wonder it was again chosen for a wide range of 21st century not only Renault-Citroen-Peugeot themselves, but even Nissan Mexican assembly, famous for their own budget and reliable janking 4-stroops for every taste.

1. Transmission Shift Laws
The gear mode of the gearbox is determined by the following information:

* Position throttle valve

Under the action of the gearbox, the computer decides to switch the transmissions based on a set of curves, called "transmission law".
Each switching law includes:

* Migration thresholds (change up and down gear)
* Thresholds of the torque converter (blocking curves)
* Points of the "Kikdown" mode

1.1. Shift curves
(Img: http: //psa-club.ru/images/stories/al4/1.jpg)

An example of the transmission shift law (torque converter blocking curves are not shown).
X - vehicle speed.

(A) The transition curve with the 2nd transmission to the 1st transmission.
(B) The transition curve with the 1st transmission to the 2nd gear.
Crossing the transition with the 3rd transfer to the 2nd gear.
(D) Crossing the 2nd gear transition curve.
(E) Crossing the transition with the 4th transmission to the 3rd gear.
(F) The transition curve with the 3rd transfer to the 4th gear.
"G" Example 1 point.
"H" Example 2 point.

Transmission change occurs when the operating point crosses the curve (speed increases or decreases).
Note: The shift thresholds are different when increasing or lowering the transmission to avoid repeated changes to the gear.
In any case, the gear shift laws allow the driver to optimally use the operating characteristics of the car in accordance with their commands.
When you press the accelerator pedal, the computer automatically switches to KD (Kick-Down) mode.

* Included 3rd Transfer
* Transmission switching occurs upon reaching a speed car 100 km / h

* The accelerator pedal is pressed by 80% of his stroke
* Included 4th gear
* Switch down occurs when the velocity of the car is dropped below 72 km / h

1.2. Curves blocking a hydrotransformer

An example of a torque transformer blocking curves (shifting curves are not shown).
X - vehicle speed.
Y - the position of the accelerator pedal (%).
(J) the locking curve of the hydrotransformer when switching from the 2nd transmission to the 1st gear.
(K) Curve the blocking of the hydrotransformer when switching from the 1st transmission to the 2nd gear.
"KD" The gearbox mode is determined by the following information.
(L) The torque converter lock curve when switching from the 3rd transmission to the 2nd gear.
(M) Curve the locking of the hydrotransformer when switching from the 2nd transmission to the 3rd gear.
(N) the locking curve of the hydrotransformer when switching from the 4th transmission to the 3rd gear.
(P) the locking curve of the hydrotransformer during the transition from the 3rd transmission to the 4th gear.
"Q" Example 1 point.
"R" point of Example 2.
Example 1: The vehicle speed increases:

* The accelerator pedal is pressed by 80% of his stroke
* Included 3rd Transfer
* Locking the torque converter occurs upon reaching a speed car 75 km / h

Example 2: The vehicle speed is reduced:

* The accelerator pedal is pressed by 80% of his stroke
* Included 4th gear
* Unlocking the torque converter occurs when the velocity is dropped below 58 km / h

2. Switching and program algorithms

(Img: http: //psa-club.ru/images/stories/al4/3.jpg)

S - work algorithm in normal mode.
T - Algorithms for protecting the gearbox from overheating.
"1" Sample Selector.
"2" Information about the temperature of the working fluid transmission.
(L1) Economical algorithm.
(L2) Medium algorithm.
(L3) Sports algorithm.
(L4) Braking algorithm 1.
(L5) Braking Algorithm 2.
(L6) Descent algorithm.
(L7) Snow Mode Algorithm.
(L8) Algorithm without blocking.
(L9) Heating algorithm.
(L10) The thermal protection algorithm.
The computer uses 10 gear shift algorithms:

* 6 autoadaptation algorithms
* 1 Feature of the switching algorithm in "Snow" mode
* 1 Algorithm without blocking
* 1 Algorithm for Hare Gearbox and Engine
* 1 Algorithm Thermal Gearbox

Algorithms listed in memory allow double switching on reduced gear.
Note: In the gearbox with pure hydraulic control, there is only one gear shift algorithm.
Note: The operation mode "Forced shift gear" limits the number of available gears. It uses thresholds used in "automatic" mode.
Automatic adjustment algorithms are ::

* Economical algorithm (when fuel economy is important)
* Middle algorithm (more sports car behavior compared to an economical algorithm)
* Sports algorithm (sports driving)
* Braking algorithm 1 (algorithm adapted to small vehicles and small slopes)
* Braking algorithm 2 (algorithm adapted to significant vehicles of the car and cool slopes)
* Descent algorithm (algorithm adapted to descents, using engine braking)

Electronic computer manages 3 drive programs:

* Normal (self-adaptive parameters)
* Sport
* Snow

The driver can choose the desired mode program by clicking on the corresponding button.
The program selection is displayed on the instrument panel by turning the corresponding indicator.
The transition to an economical program is achieved by pressing the button corresponding to the active program.
When the ignition is turned on, the gearbox is always installed in the program "Normal driving" program (self-adaptation).

2.1. Normal Driving Program (self-adaptive parameters)
A program adapted to a normal driving manner (when fuel saving is important).
The computer adjusts the action of the gearbox to the state of the road, the engine load and driving style.

U is the driver's algorithms.
V - Algorithms "Car Load".
(L1) Economical algorithm.
(L2) Medium algorithm.
(L3) Sports algorithm.
(L4) Braking algorithm 1.
(L5) Braking Algorithm 2.
(L6) Descent algorithm.
(LC) Selected algorithm.
With the "normal" job, the computer uses 6 gear shift algorithms:

* 3 Algorithm characterizing the driver's behavior (economical algorithm, medium algorithm, sports algorithm)
* 3 Algorithm characterizing the profile of the road and the load of the car (braking algorithm 1, braking algorithm 2, descent algorithm)

The computer selects the most suitable algorithm among the driver's algorithms and the "car load", as well as depending on the specified priority level.

2.2. Normal Driving Program (self-adaptive parameters): Select the "Driver" parameter
The computer determines the algorithm that is most suitable for driver behavior:

* Economical algorithm
* Medium algorithm
* Sports algorithm

The choice is carried out on the basis of medium values \u200b\u200band last minutes actions.
The choice can be instantly adjusted (see the "Instant Increase Increase").

* The speed of change of the position of the throttle
* The average position of the throttle
* Changing the speed at the output from the gearbox (speed sensor at the output)

2.3. Normal Driving Program (self-adaptive parameters): Selecting the "Car Load"
The computer determines the algorithm that is most suitable for changing the load of the car:

* Brake algorithm 1
* Braking algorithm 2
* Algorithm descent

Basic information taken into account:

* Periodic opening control (RCO)
* Acceleration of the car (engine torque)
* Car speed

2.4. Normal Driving Program (self-adaptive parameters): Selection of the algorithm used (LC)
After the computer determines the "Driver" and "car load" algorithms, it chooses the most suitable algorithm.
The selection is carried out in accordance with the specified priority level.
(Img: http: //s39.radikal.ru/i084/0811/3e/f5aec58a678b.jpg)

2.5. Snow Program
A program adapted to move along the road with a weak clutch of the wheels.
Features:

* Prohibition of the transition to the 1st gear. Selector gearbox in the "D" position
* Switching ranges happens less frequently than with other programs
* Short press Accelerator pedals (kick-down) causes a transfer to reduced transmission if the vehicle speed is below 15 km / h
* Soft work (no sudden changes in the moment transmitted to the wheels)
* Forced switching down when braking

In the "D" position, the touch is carried out with the 3rd transmission.

2.6. Sport program
The program is adapted to K. sport driving (to the detriment of fuel consumption).
Gear shifts occur on increased engine modes (to increase the car dynamics).

3. Special algorithms
3.1. Algorithm without blocking

* When the temperature of the working fluid of the gearbox is below 0 ° C when the engine is started (transmission oil fluidization)
* When the temperature of the clutch clutch clutch is too high (calculated value)
* If the lock is malfunction (slipping)

Note: This work algorithm is turned off if the temperature of the working fluid reaches 15 ° C.
3.2. Heating algorithm

Note: In the snow program, the law of switching in the "Snow" mode is prioritized with respect to the law of protection against overheating.
4. Other functions with automatic adjustment
4.1. Prohibition on the inclusion of increased transmission (rapid lifting of the leg)
This feature does not allow to occur inappropriate inclusion of increased transmission with a rapid lifting of the leg (engine braking).
Note: This feature is also active when the car moves on the descent, "mass".
4.2. Instant switching to sports driving mode
This feature is included with the quick press of the accelerator pedal in the "normal" mode.
The computer temporarily moves to a more sporting algorithm of work, which provides greater engine pickup.
Example:

* If an economical algorithm was used, the computer proceeds to the middle algorithm
* If an average algorithm was used, a computer moves to a sports algorithm

Note: When the ancorerator pedal is released, the computer immediately returns to the algorithm used until the transition to the sports mode.
4.3. Transmission block when changing the algorithm
In some cases acting transmission Blocked when the computer changes the working algorithm.
Transmission blocking is removed under the following conditions:

* Foot raised with accelerator pedals
* Acceleration of the car after a specified time interval

5. Inclusion of reduced transmission when braking
Enable reduced transmission when braking is automatically adjustable function.
Note: The reduced transmission can be enabled under some driving conditions (in accordance with the law used).
6. Function "Exhaust Live Liquid"
This function allows you to calculate the workshop of the working fluid transmission.
Conscribed parameters:

* Oil temperature
* Time during which the working fluid is exposed to high temperature

Based on these parameters, the computer increases the value of the exhaust fluid meter.
In normal operations of the gearbox, the computer increases the counter to small values.
In difficult operating conditions (very hot working fluid), the computer increases the counter to the big values.
With a new computer, the exhaust fluid meter starts counting from 0.
When the counter comes to 32958, this means that the working fluid is fully worked out: the "Sport" and "Snow" indicators are blinking.
Note: The level of wear of the working fluid transmission can be determined using a diagnostic device by measuring parameters.
7. Hydraulic functions
7.1. Regulation of the main fluid pressure
The magnitude of the pressure of the fluid in the main line is determined by the transmission of the gearbox depending on the torque of the engine.
This fluid pressure allows you to activate clips and brakes.
The main fluid pressure can be continuously adjusted:

* Between 3 and 12 bar: in the gear shift phase and on transmissions 2, 3 and 4
* Between 12 and 21 bar: when starting the engine

In neutral position, the main hydraulic pressure is 3 bar.
Pressure correction is performed by means of a pressure modulation electroclap in the pressure line (EVM pressure).
Adjustment is based on data coming from pressure sensor.
The main pressure control of the fluid is carried out with an open circuit in the following cases:

* Pressure sensor malfunction
* Selector lever in neutral position
* Pressure control fault (pressure sensor malfunction)
* Basic hydraulic pressure above 12 bar (large torque)

7.2. Coupling control lock
The lock clutch may be in one of the following states:

* Disabled
* Included

The disconnected lock state allows you to:

* Enlarge the moment of the engine when driving a car
* Prevent unwanted engine stop
* Smooth out the uneven engine rotation
* Promote the cooling of the clutch node
* Light fluid (frost) and promote engine warming

The locked status on allows you to:

* Reduction of fuel consumption
* Promote the cooling of the production fluid transmission (increased oil temperature)
* Provide braking engine under certain conditions driving
* Exclude slipping

The torque converter can be blocked at 1, 2, 3 and 4 transmissions.
Note: The 1st transmission can be blocked only under the following conditions: the car is loaded, movement with a sharp rise, the temperature of the working fluid is too high.
The threshold values \u200b\u200bfor blocking the torque converter constitute an integral part of the gear shift laws.

French PSA automaker (Peugeot Citroen Association) together with Renault, launched this 4-speed automatic transmission into the series DP0. (she is - Al4.) in 1999.

Al4 automatic transmission is calculated for the front drive and motors from 1.4 to 2 liters. There are a large number of options for drive gears and housings. Designers argue that DP0 can transmit torque to 210 nm. But the manufacturers were forced to "fasten" settings, without bringing the transmitted torque to the limit so as not to allow the owner to kill the back cover and ensure mileage to overhaul over 150-200 TCM.

Automatic Al4-DP0. It is a unique and pretty successful development of French engineers. Its design is ingenious simple and very rational: "nothing superfluous."And as a result, it has a low cost.These advantages helped to sell more than 1 million machines with the DP machine and at the same time created a headache (pleasant, perjuditable box) for automatic transmission masters.

It is believed that the AL4 transmission itself is easily running to 200 tkm, and with normal operation and timely maintenance / overhaul and up to a million.

Cooling automatic transmission

DP0 has a heat exchanger for cooling oil. All transmissions with the heat exchanger work in the temperature mode close to critical. In the summer of automatic transmission DP0.regularly overheats, the electrician suffers, namely the hydraulicock. Such is the constructive feature of many automatic transmission with the heat exchanger. The duty after runs for 80-100 TCM lies on the owner.

It should be borne in mind that at the operating temperature +75 .. + 90 ° DP0 is almost eternal. The more load it at low and too high temperatures, the earlier the premature old age of elements is coming. In addition, the programmers allowed the gas-dried in the floor in the floor with the 2nd speed to include the mode of forced locking the coupling, which reduces the heating, but accelerates the pollution of oil and wear.

Frictions pollute the oil, dirt settles in the heat exchanger, (which also works as a filter) and as a result, after critical pollution of the heat exchanger, the oil in the heat does not have time to cool. Why hydrophlitis (and solenoids) cease to work normally. And the dirtier oil, the higher the operating temperature and the worse controls the switching speeds of the hydraulicock.

The heat exchanger is not accepted due to its too high price and short reserve on the resource. It is washed with large quantities of cheap ATF oil (internal) and antimes - an outer contour. But it is easier and more efficient to embed additional cooling instead of the tired heat exchanger slaughtered by resins. Most masters prefer to install the radiator along with.

Developed -Adapters for the installation of the radiatorleft 144998 instead heat exchanger DP0. An external ATF cooling and thermostat 100099 are already connected to the adapter.

Replacing oil and filter

Oil filter automatic transmission for all models is the same - No. 144010. Metal-plastic filter of fine cleaning has a felt bag and requires replacement every ... however, the automatic transmission experts exist opposite opinions about changing the oil and filter DP0: from "unplaced oil" to "change every 20 thousand km."As one rabbi judged: ".. and you are right, Moisha, and you, Semyon."

But as aging and wear and the accumulation of dirt in the oil begins a chain wear reaction with oil pressure loss. The pump serves increasingly oil, but it comes to packages less and less pressure and dirty oil is risening through the slots of seals and the sleeves is all more intense. And after 150-200 TCM really needed or change the oil ("partial" replacement) every 20 TCM, and it is necessary - a regulatory overhaul of the box and a torque converter is required. Well, or change the machine to the new one.

The older aggregate, the greater the wear of the "iron" nodes and the faster the oil is polluted.

The resource of this automatic transmission to the overhaul with a neat and correct operation can be 150-200 tkm, and after timely repairs with full bulkhead and replacement of consumables can be extended to half a million if the machine itself is still on the go.
