The automatic transmission model DP0 / AL4 is equipped. The average life of this transmission to overhaul - 200 thousand km. Run. Solenoids of automatic transmission, which, in fact, are consumable elements inside the velocity box, for the first time you need to change on a run from 70 tons. Km. Usually, two solenoids are changed at once, most loaded and therefore often failing.
If you regularly change the liquid into the automatic transmission (every 30-50 t. Km.), Do not exploit the box with overload (buxation, riding with a trailer, riding at the limiting speeds for a long time, etc.), then the DP0 can last and up to 250 t. km
General signs of problems in Dr. Peugeot:
- Foreign noise
- Vibration
- Shock
- Boots
- Oil leakage in automatic transmission
- Specified Dark Oil
All listed symptoms can talk about the need to prevent or repair automatic transmission.
Problems specific to DP0 automatic transmission
- The automatic transmission rises into the emergency mode (most often the diagnostics will reveal a pressure error)
- Sensitive "jerks" from 1 to 2 transmission. Manifests itself in "traffic jams" on a small gas
- The automatic transmission does not switch to 2, 3, 4 transmissions.
- The car does not move in R and D mode.
- "Throw" turns of DVS by tachometer without changing the velocity of the car (thrust loss). Basically occurs when shifting gear.
Peugeot cars with an engine over two liters
Such Peugeot are equipped with the automatic transmission model of the TF80SC. This is a Japanese transmission box of the AISIN concern. According to statistics, the average service life before the overhaul of this automatic transmission, with regular maintenance and a calm driving manner, is approximately 180-220 thousand km. Run. At best, this indicator may exceed even 280 tons. Km
However, if you regularly change the liquid into the automatic transmission, then the initial repair of the unit is possible on the range of the car in 120-150 tons. Km. Although this automatic transmission for Peugeot is quite reliable, but from its specific problems it is worth noting "fear" overheating and criticalness to the quality of fluid.
Complaints in the execution of automatic transmission can be quickly and relatively inexpensive (especially, when compared with overhaul), eliminate if you contact a specialized service after the first symptoms.
And produced at the enterprises of Peugeot
Automatic It has four front-end transmissions, one rear and clutch of a torque converter:
- Maximum torque: 210 HM
- Mass: approximately 75 kg.
- Active and autoadaptive automatic transmission system
An identification index is installed on the machine. Engraved on the lid it consists of an index of the manufacturer's enterprise and the product serial number.
The AL4 automatic transmission consists of four parts:
- Chief block
- Block of the hydrotransformer
- Block of the hydraulic assembly
- Cap
The unit of the hydraulic node is in the rear of the automatic transmission. It does not equip the oil level dipstick
In addition to the usual transmission modes, the AL4 automatic transmission has a sequential mode ( tIPTRONIC PORSCHE Type Sequential Switching) Switching the driver and the selection of special programs such as sport mode, and the forced inclusion of the first and second transmission.
The principle of operation of the hydraulic part of the automatic transmission does not differ from the principle of operation of an ordinary torque converter. It is equipped with a double-sided coupling of a hydrotherapist blocking, which provides a mechanical connection between the engine and the automatic transmission (automatic)
Transfer torque.
The torque converter blocking clutch is controlled by a hydraulic manner using a solenoid valve located on the hydraulic unit block. The mode of operation of the torque locking clutch is laid into the computer's computer program.
It has:- Four front progels
- Reverse passing
- Neutral position of the selector
This is a planetary transmission of type "Simpson 2"
Also, the automatic transmission has a mounted speed sensor.
In the circuit of the hydraulic automatic transmission system there are:
- oil pump
- net filter
- hydroaccumulator
- thermostat
- heat Exchanger
- electromegnity flow valve through heat exchanger
- six electromagnetic sequenal switching valves
- unloading valve
- electromegnity pressure adjustment valve
- pressure limiter
Sensors ACPP AL4.
The oil temperature sensor in the box is built into the inner wiring near the hydroblock and informs the computer about the oil temperature inside Automatic.
The turbine wheel rotation sensor is set next to the left wheel drive, informs the computer about the rotation of the turbine wheel, the sensor information determines the decision to switch the transmission, also determines the slides in the torque converter.
The rotation sensor at the output is immediately behind the main electrical block, it informs about the frequency of rotation of the output element. Together with information about the frequency of rotation of the turbine wheel, the transmission is needed. Also transfer information about the slip (slipping clocking) and brakes, to determine the required moment to switch. In Peugeot 307 and 807, the information of this sensor is replaced with the information of the speed sensors, which provides the ABS and ESP system.
Linear pressure sensor. Installed at the bottom of the box. It provides a computer information about the value of linear oil pressure. This information gives the computer with the ability to compare the measured pressure with the value of the entered into the computer, as well as adjust it to affecting the pressure electromagnetic valve.
Computer automatic transmission
Computer box has in touch:
- with an ABS system to support the transfer included when regulated
- with info on fan operation, to improve cooling
- with the climate control system, to turn off when switching
Safety Safety Related with Kulisa (Selector Lever):
In order to avoid different errors when driving a car equipped with an automatic box, a protection system is introduced, associated with the lever of the scene (selector)
- System "SHIFT LOCK"
The SHIFT Lock function blocks the selector lever in the parking position (P), using an electromagnet installed in the selector panel. Unlocking the selector occurs when the ignition is turned on and the brake pedal is pressed.
- Function "Key Lock"
Mechanical key lock (prevents it from removing from the lock) If the position of the selector when the ignition is turned off, is not in the parking position.
- Engine start locking
Blocks engine start if the selector is not in the parking position or neutral position.
Next to the lever of the selector are the program shift buttons
- Sport program
Switching gear occurs on increased engine speeds, when slowing down, switch is delayed.
- Snow Program
Torting from the place of the car makes from the second or third transmission, the gear shift occurs less frequently.
- Program "1"
Included forced first transmission.
EOBD Light Signal (Check-Engine)
He warns the driver about the presence of anomalies (errors) in the operation of the automatic transmission that is able to worsen the operation of the toxicity reduction system. Computer box reveals an error and transmits its engine to a computer, which in turn includes alarm Eobd.

How to check the box automatic (automatic transmission) - Tips and recommendations How to replace the oil in the automatic transmission Al4 Peugeot, Peugeot? Arrived partner for repair box
Repair of automatic control of Peugeot - Our profile. What is the resource from the Peugeot automatic and how to extend your life?
To begin with, let's say a few words about the AL-4 automatic transmission itself.
Adaptive AL4 automatic transmission with the Tiptronic System Porsche system is installed on most Peugeot and Citroen cars, produced in France in PSA and Siemens partnership. The box is old enough, however, in 2004 it was a little modernized and eliminated some of the "children's diseases".
The first, the most common automatic transmissions of AL4, installed on Peugeot 206, 307,406, 407, Citroen Xantia, Xara, C4, C5 of the first years of release were especially unreliable. On fresh cars, the characteristic "diseases" of AL4 are much less common, but only under conditions of proper operation and frequent oil replacement. Nevertheless, Dr. Peugeot, alas, are still far from ideal. So that Repair of automatic control of Peugeot 308, 307, 206 after 2-3 years of operation - the usual thing.
How to avoid fast repair Peugeot?
To extend life automatic transmission peugeot, avoid the emergency mode and overhaul of the automatic transmission of Peugeot or Citroen, it is necessary to comply with several rules of operation and maintenance of the "automatic". This is especially true for the "problematic" automatic transmission of AL4, installed on Citroen and Peugeot.
It is necessary to warm the box-machine as well as the engine in the cold season (when heated, switch the automatic transmission lever to the "Drive" lever, without forgetting to put the car on the "handbrack");
Try to avoid slipping wheels on a slippery road;
Do not switch without the need for the transmission position selector lever;
Cut the periodic (every 30 thousand km) partial or complete (in the case of dismantling the box) Replacing the oil automatic transmission of Peugeot Citroen (LT71141). This moment is especially important, for official dealers this procedure is carried out only at the request of the client, because the cunning manufacturer does not recommend changing the oil in the automatic box in general. (We must sell boxes). Here and "go" the automatic transmission of Peugeot thousands of 60 kilometers, although, with a regular replacement of oil once a year, could serve at least three times longer.
So we advise you to carry out the maintenance of automatic transmission with prophylactic diagnostics.
How does your Peugeot show when the automatic transmission is required?
When should I go to "Dr."? When necessary repair automatic transfers 307, how much will the repair of the automatic transmission of Peugeot 308 cost, how to understand that your kid is Peugeot 206 "covers" automatic transmission?
Usually everything starts with shocks and jogs when switching gear. At this stage, a simple replacement of hydroblock solenoids can help.
It happens that it even helps for a long time. With the further development of "disease", either sports regime, or winter automatic transmission mode, is shown spontaneously. "AUTOMATING" rises into the emergency mode and does not switch above the third transmission. In this case, no longer do without overhaul.
Account repair cost
On average, the repair of automatic control of Peugeot is not very expensive. If we are talking about replacing the solenoids of the hydroblock - in our car service it will cost about 15 thousand rubles along with spare parts and oil.
Overhaul of automatic transmission Peugeot costs from 30 to 90 thousand rubles, the exact cost is determined after removing the automatic transmission from your Peugeot or Citroen, opening the automatic box and its defective. When defecting, the condition of brake drums and ribbons, friction, hydroblock, pistons, oil pumps look. The hydrotransformer (bagel) is mandatory revealed and repaired, all the bronze bushings, seals, etc. are also changing. After assembly, the automatic transmission of the hydraulicock is already adjustable by the machine using the diagnostic computer.
Replacing the oil in Dr. Peugeot and Citroen costs 3000 rubles. So it is more profitable to change the oil more often and forget the repair of a Peugeot automatic transmission for a long time.
This looks like a hydraulicone, just removed from the AL4 automatic transmission. Green numbers 1 and 2 are marked by the ill-fated hydroclap.
Such well-known car manufacturers as "Citroen" and "Peugeot" establish the popular AL4 automatic transmission on most of its own models. Developing this unit, engineers set a goal - it should be economical and simple. As a result, Al4 turned out to be a weak link of the car.
Signs of what is needed repair box automatic al4 Serve suspicious shocks or even shocks in the automatic transmission when switching from one transmission to another. "Conditioning" such a malfunction, easy to eliminate it, replacing the solenoids of the hydroblock.
Overheating The most "favorite" problem of French automatic boxes. Turning to our car service on time, it will be "cured" by Al4 relatively inexpensive, as the prices for repair ALCP AL4 (AL4) in Moscow, still "democratic".
Such a "disease" as a spontaneous change of modes is the most running for AL4. To solve this problem, a solid major overhaul is required.

ACP AL4 is one of the most famous automatic transmissions that are used on the front-wheel drive vehicles. It was developed in 1999 by the French Peugeot Citroen Association. According to Renault classification, this box is called DP0 and in Russia the most famous is under this naming. Initially, it was put on the following Renault models: Clio, Symbol, Laguna (front-wheel drive cars with an engine volume no more than two liters). Subsequently, Al4 got the Peugeot models (207, 208, 308, 407 and others), and Citroen (C2-C5, XSARA).
The gearbox has 4 main modes of operation, as well as neutral and warm-up mode.
1. Normal mode of operation
- The position of the gearbox selector D includes autoadaptive switching mode. In this mode, the on-board computer independently selects the modes in which the transmissions are switched: from the most environmentally friendly to the most dynamic. The choice of a specific program depends on the load on the motor, driving style and road conditions. Select mode, as a rule, occurs in about 10-15 seconds.
- The position of the gearbox selector 2 is similar to D, only without using III and IV gears. Also in this position of the selector it is possible to use the button 1, which is used for emergencies and complex road conditions: when you press this button, the gearbox selects only the first gear.
- The position of the gearbox selector 3 is similar to D, but without IV transmission.
2. Sports mode (S)
- The position of the box of the box D includes the most dynamic of 6 modes of operation of the automatic transmission.
3. Winter mode of operation (button *)
- The position of the selector D includes the most eco-friendly mode of operation and does not allow the use of i gear, the machine is touched from the second. It is implemented in order to prevent slipping on a slippery road.
Modes of operation automatic transmission AL4
4. Sequential mode of operation (Pressed M button)
- In this case, the driver switches the transmission itself. However, when reached the minimum threshold value of revolutions for each transmission, AL4 will independently turn on the reduced transmission, when maximally revolts are reached - increased.
The design of Al4 is quite simple, no additional "frills" in it is not that somewhat enhances operational requirements. It should be treated carefully, otherwise the box declared in a technical transportation will not pass - the problems will begin with 50-60 thousand (Russian conditions of operation are affected).
- Despite the fact that the box has warm-up mode, which turns on automatically after the start of the engine, the box should be warmed every time after a long parking lot. Hall the brake, move the gearbox from the parking mode (P) to the reverse mode (R), wait a couple of minutes, move the box to movement mode (D) and wait another two minutes. After that, you can start moving.
- In order to extend the service life of DP0, immediately after the start of the movement, do not allow harsh accelerations using reduced transmissions for fast acceleration.
- Do not slip slip. In the cold season, use the Winter Mode of the box. If it did not help and you are stuck in the snow, do not overload the box, ask someone to push the car. Even if these are random passersby and they have to pay, remember - the repair is much more
Al4 design
- If the box independently includes alarm mode (the program III turns on, PRND appears on the panel), this suggests that the working pressure is exceeded. It threatens overheating box, faster wear and out of the ranks of frictional, so contact the car service.
- Support the optimal temperature mode of the vehicle and make sure that the coolant radiators are clean.
- Keep track of the oil level in the CP - for this regularly visit the car service (the fact is that there is no probe to check the oil level in the automatic transmission, so the oil level control is possible only in a hundred). However, the exceedable oil level is easy to notice on oil subkam.
- Every 20,000 kilometers are made to replace oil in the box and its computer diagnostics - do not give in touch with the manufacturers that the box is maintenance-free (important! In the early 2000s, manufacturers have stated that the box should be serviced in 20 thousand, after the regulations changed, but the design of the box remained the same). In the box only 6.5 liters of oil, but due to the design features, it will not be possible to change it entirely, about 4 liters are replaced.
Features of normal operation ACP AL4 (DP0)
Normal Driving Program (self-adaptive parameters)
Al4 box has several features of work characteristic of it. If something from the following occurs during the operation of the automatic transmission, there are no reasons for concern - these are normal phenomena when working the box, fear that something failed is not worth it.
- On an immentable box in selector mode D, the transition from i on II transmission is carried out with a noticeable push (therefore, as mentioned earlier, the box should be warmed every time before departing).
- Sharp braking also causes an impetus when switching from II to I, and this does not depend on the degree of health. The sharper braking takes place, the stronger will push. "Machines" do not really like torn rhythm ride.
- When switching from parking (P) to movement mode (D or R), the increased load on the engine is felt due to the operation of the hydrotransformer.
- With a sharp switching from the movement mode to the reverse mode (and on the contrary) there is a noticeable blow to the box. Moreover, it is characteristic not only for Al4, but for many other machines - before switching the direction of movement, a complete stop of the machine is necessary!
- The push when switching from i on II is not felt in the winter and sports modes of the gearbox. It is quite logical - in winter mode, the car starts with the second transmission, and in sports switching occurs over three thousand revolutions.
- When you click on the brake, a click is heard, thus the blocking is released.
- When starting the car in a hillside from the parking mode, it has a small rollback (about 10 centimeters).
AL4 There are several features of work
Typical Al4 Box Malfunctions
The most famous malfunction arising from this automatic transmission is the failure of the electro-hydraulic valves, which the people are called "solenoids". These valves are in the hydraulicone, one of them is responsible for controlling the oil pressure, and the second provides the torque of the torque converter. As a rule, if these valves fail (or incorrectly), the box switches to the alarm mode, the third transmission turns on. The main danger of this malfunction is that the torque converter is blocked, the box pump creates high pressure (from 10 atmospheres). Because of this, the box "burns", or breaks the brake tape earrings.
Also often occur faults of the automatic transmission sensor. On vehicles with a large mileage, this sensor often begins to produce incorrect readings (the pressure measurement error increases by about 100 times), which leads to an error of pressure adjustment and incorrect operation of the machine. Another problem with which motorists are often faced - the incorrect operation of the hydrotransformer itself.
Some errors in the operation of the transmission are not at all connected with the box itself, but again, they will result in an error message of the gearbox, its switching into emergency mode. Such faults include, for example, brake wiring faults.
al4 Box faults
findings
This is one of the most popular boxes put on French cars. Its design is simple, but requires quite a thorough compliance with operational rules. There are nuances, for example, the box is prone to overheating. However, there are obvious advantages - the planetary mechanism of the box is exclusively reliable, the control electroble also works fine. Do you buy a car with such a box? Many motorists consider it not enough reliable for Russian operating conditions. If you carefully follow the status of your car, love a quiet ride and carefully treat the transmission - Al4 will not give you a reason for anxiety. If you prefer the "torn" driving rhythm, quick overclocking with frequent switching, then it is better to choose a more appropriate option.
