Like most modern car manufacturers, Renault claims that the transmission oil is designed for the life of the gearbox. This refers to the normal operating conditions of the vehicle. But any, even the highest quality oil cannot function forever, the properties of the product are lost over time, ceasing to provide full-fledged operation of the box. After 5 years of service, the lubricant inevitably ages, becomes less viscous and ceases to perform its assigned tasks, which leads to wear of the device. The motorist himself may notice manifestations of instability in the operation of the box, associated with the need. For this reason, changing the oil in the Renault Symbol manual transmission is a mandatory procedure, which is performed in order to prevent undesirable consequences in the form of repairing the device.
It is better to change the oil in the Renault Symbol manual transmission with ELF Tranself NFJ grease.
Replacement frequency
Change of transmission oil every 50 - 75 thousand km. mileage or once every 4 - 5 years will significantly extend the service life of the manual transmission and avoid the need for repair. In addition, the conditions in which the car is operated, as well as the driver's driving style, should be taken into account. Under certain factors of influence, the lubricant wears out much faster. Oil leaks are also possible, significantly reducing the resource of the manual transmission. If you purchased your vehicle from the aftermarket, it is best to change the lubricant immediately. Sometimes an unplanned replacement may also be required. In the event of extraneous noise, tight gear shifting, it is necessary to check the level and condition of the lubricant, then, depending on the situation, add or replace the agent.
What kind of oil to pour
The automaker recommends using ELF Tranself NFJ gear oil with a viscosity of 75W80 in manual transmissions. For replacement, you will need to purchase 3 liters of the original product. If you use a suitable product for Renault Symbol, change it in time, regularly check the lubricant level, the manual transmission in all gears will work smoothly, without jerks and.
Checking the oil level
Timely in the manual transmission will ensure the stability of the device. If the fluid level reaches a critical level, the driver may notice a malfunction of the box, which results in the need for repair. It is also necessary to check the Renault Symbol gearbox for leaks, because this problem is not uncommon. It is necessary to carry out the verification procedure at intervals of 10-15 thousand km. mileage, depending on operating conditions, as well as in the presence of noise effects or indistinct gear changes.
There are two ways to check the oil level in the Renault Symbol box:
- using an oil dipstick;
- determine by the edge of the oil filler hole.
Remove the measuring device, wipe it dry and replace it, then remove it again. The lubricant should be at the level of the maximum mark of the measuring device or be poured along the neck (for a car where there is no dipstick). Before unscrewing the plug, first place the container, the grease may leak out a little. The level should be at the bottom edge of the filler hole. Add oil with a syringe if necessary.
Partial replacement
In order for the manual transmission you will need the following tools and materials:
- recommended gear oil;
- 8 mm square key;
- syringe or long tube with funnel for refueling;
- new copper seals for plugs;
- gloves, clean rags;
- capacity for working off.
For the manual transmission, do the following:
Complete replacement
With a partial replacement, the oil is not renewed one hundred percent, therefore, in some cases, a complete replacement method is required. For example, if you need to switch to a different product from the previous one. This option involves flushing the assembly before filling the box with new grease. The filler plug is unscrewed, and a liquid is poured through it, flushing the manual transmission with the engine running. After draining the flushing, new oil is poured.
Changing the oil in a manual transmission is faster and easier than in an automatic transmission, since the manual transmission does not have filters that need to be changed in the process. Also, to completely replace the lubricant, all actions are performed manually. The transmission fluid in the automatic gearbox is changed using special equipment.

1.Specifications
Vehicles with automatic DP0 gearboxes are equipped with Shift Lock and Lock up systems.
The "Shift Lock" system locks the movement of the selector lever if the brake pedal is not pressed at the same time.
NOTE
When providing technical assistance in the event of a battery failure, follow the instructions in the vehicle operating instructions.
The "Lock Up" or torque converter lock-up system allows the automatic transmission to communicate directly with the engine. This is realized thanks to the "mini-clutch" installed in the torque converter.
The "Lock Up" system is controlled by the ECUAKP.
Lubrication of the automatic transmission is carried out under pressure, therefore, it is only ensured when the engine is running.
Therefore, to avoid serious damage, the following rules must be followed:
- in no case ride with the ignition off (for example, on a downhill);
- do not move the car by pushing it (for example, to roll it to a gas station). If the need arises, take precautions;
Since the car's wheels are driven only when the engine is running, it is impossible to start the car engine with the automatic gearbox by pushing it.
2. Safety precautions while working with automatic transmissions
1. The automatic transaxle is made of high precision parts, which requires careful inspection before reassembly, because even a small scratch can cause fluid leakage or affect performance. The repair instructions are organized so that you only work on one group of elements at a time. This will help to avoid confusion from similar parts of different subsystems at the same time in your workplace. Inspection and repair of groups of elements starts from the side of the converter housing. Inspect, repair, and reassemble them before moving on to the next group of items. If, when reassembling, you find a defect in a specific group of elements, immediately inspect and repair that group. If it is not possible to immediately assemble a group of elements (waiting for ordered parts, etc.), place all the parts of the group in a separate container.
2. All disassembled parts should be washed, all channels and openings purged with compressed air.
3. Dry all parts with compressed air, never use rags.
4. When using compressed air, do not direct the air stream towards yourself to prevent accidental splashing of the working fluid or kerosene on your face.
5. Clean parts only with recommended automatic transmission fluid or kerosene.
6. After cleaning, re-arrange the parts in the correct order to ensure effective inspection, repair, and reassembly.
7. When disassembling the valve body, store each valve with its associated spring.
8. Place new discs for brakes and clutches that will be used for replacement in a container with working fluid for at least 15 minutes before reassembling.
9. Coat all o-rings, discs and clutch plates, rotating parts and friction surfaces with hydraulic fluid before reassembling.
10. Replace all gaskets and rubber O-rings with new ones.
11. Do not use sealants on gaskets or similar parts.
12. Make sure the ends of the snap ring do not line up with any of the notches and are seated correctly in the groove.
13. When replacing a worn bushing, replace the subsystem containing that bushing as well.
14. Check the thrust bearings and their tracks for wear or damage. Replace if necessary.
15. Use Vaseline to hold the parts together.
16. When working with the material of the gasket, which is finally formed in the working position, you must follow the following procedure.
Using a razor blade and scraper, remove all old gasket material from the sealing surface.
Thoroughly clean all elements from the removed cushioning material. Clean both sealing surfaces with a non-marking solvent.
Reassemble within 10 minutes after applying the gasket to the sealing surface. Otherwise, the gasket material must be removed and replaced with a new one.
2.1. Towing
In all cases, it is preferable to transport the vehicle on a platform or tow it with the front wheels hanging.
At the same time, in exceptional cases, it is allowed to tow the vehicle at a speed not exceeding 20 km / h and at a distance of not more than 30 km (the selector lever must be in the “N” position).
2.2. Applied oil

Functions of ATF in Renault automatic transmission Symbol:
- effective lubrication of rubbing surfaces and mechanisms;
- reduction of the mechanical load on the units;
- heat removal;
- removal of microparticles formed due to corrosion or wear of parts.
- wear of automatic transmission oil seals;
- wear of the surfaces of the shafts, the occurrence of a gap between the shaft and the sealing element;
- wear of the automatic transmission sealing element and the speedometer drive shaft;
- backlash of the input shaft of the automatic transmission;
- damage to the sealing layer in the joints between the parts of the automatic transmission: pallet, automatic transmission housing, crankcase, clutch housing;
- loosening of the bolts that ensure the connection of the above-mentioned parts of the automatic transmission;
Due to a lack of oil or low-quality oil in the Renault Symbol automatic transmission:
- plungers and channels of the valve body are clogged with mechanical particles, which leads to a shortage of oil in the packages and provokes wear of the sleeve, rubbing parts of the pump, etc.;
- steel transmission discs overheat and wear out quickly;
- rubberized pistons, thrust discs, clutch drum, etc; overheat and burn out;
- the valve body wears out and becomes unusable.
You can check the oil level in the Renault Symbol automatic transmission using a dipstick. The oil dipstick has two pairs of marks - the upper pair Max and Min allows you to determine the level on hot oil, the bottom pair - on cold oil. Using the dipstick, it is easy to check the condition of the oil: you need to drip oil onto a clean white cloth.
When choosing a Renault Symbol automatic transmission oil for replacement, you should be guided by a simple principle: it is best to use an oil recommended by Renault. In this case, instead of mineral oil, you can fill in semi-synthetic or synthetic, but in no case should you use oil "lower class" from the prescribed one.
Synthetic oil for automatic transmission Renault The symbol is called "irreplaceable", it is poured for the entire service life of the car. This oil does not lose its properties under the influence of high temperature and is designed for the very long life of Renault Symbol. But we must not forget about the appearance of mechanical suspension as a result of wear of the clutches with a very significant mileage. If the automatic transmission has been operated for some time in conditions of a lack of oil, it is required to check the degree of its contamination and, if necessary, replace it.
Methods for changing the oil in the Renault Symbol automatic transmission:
- Partial oil change in the Renault Symbol box;
- Complete oil change in Renault box Symbol;
A complete oil change in the Renault Symbol automatic transmission is performed using an automatic transmission oil change unit, by specialists in the car service. In this case, more ATF oil will be required than the Renault Symbol automatic transmission can accommodate. One and a half or double volume of fresh ATF is used for flushing. The cost will be more expensive than partial replacement, and not every car service provides such a service.
Partial ATF oil change in Renault Symbol automatic transmission box according to a simplified scheme:
- Unscrew the drain plug, drain the old ATF oil;
- We unscrew the automatic transmission pan, which, in addition to the bolts holding it, is processed along the contour with a sealant.
- We get access to the automatic transmission filter, it is advisable to change it with each oil change, or rinse it.
