The manufacturer provides for checking the level of the working fluid in the automatic transmission every 30 thousand km of run, and the replacement of the fluid is regulated every 150 thousand km of run. However, the need to replace the fluid may arise earlier than the specified mileage when operating the car in difficult road conditions (for example, in a large city with heavy traffic or in mountainous terrain), in case of contamination or the appearance of a burnt smell. In the latter case, contact the service, since in addition to replacing the fluid, they will carry out diagnostics of the gearbox due to the fact that the listed signs may indicate its damage.
WARNING: Use DEXRON VI fluid recommended by the manufacturer. Use of other fluids or oils will result in transmission malfunction or failure.
1. Start the engine and warm up the gearbox. The temperature of the fluid in the gearbox should be 50-80°C. To speed up the warming up, you can take the car for a short drive. Usually, at an ambient temperature of 20°C, a 10-minute drive is enough.
NOTE: The temperature of the working fluid is determined using special diagnostic equipment connected to the vehicle's diagnostic connector or using information on the central information display, if the on-board computer has this function.
2. Place the vehicle on a level, horizontal surface and apply the parking brake.
3. Press the brake pedal and hold it down, alternately move the selector lever to all positions from "P" (parking) to "D" (forward movement), briefly in each position to allow fluid to fill the torque converter and hydraulic system. Then move the selector lever to the "N" (neutral) position. Release the brake pedal.
NOTE: The working fluid level changes depending on the temperature. Checking the fluid level at low temperature will result in overfilling, and checking the level at high fluid temperature will result in underfilling. Overfilling or underfilling will impair the operation of the transmission.
4. Remove the engine crankcase guard (see "Removal and installation mudguards and engine crankcase protection").
5. Place a wide container under the gearbox to drain the working fluid.
6. Loosen the tightening of the plug of the hole for checking the working fluid level...
7. ...and turn it inside out.
8. Start the engine and let it idle. At a normal level, the working fluid will start to flow out of the hole when the temperature reaches 35-37°C.
9. Assess the condition of the working fluid. If it is dirty or smells burnt, replace it completely.
WARNING: A burnt smell of the working fluid, combined with the presence of foreign particles in the form of fragments of friction material, indicates the need for gearbox repair.
10. If the working fluid does not start to flow out of the inspection hole when the temperature rises to 45°C, add fluid.
11. Unscrew the plug of the hole for filling the working fluid...
12. ...and take it off.
NOTE: The plug is sealed with a rubber ring. Replace the ring if it is too tight, hardened or torn.
13. With the engine idling, add working fluid until it starts to flow out of the inspection hole.
NOTE: The fluid should flow out of the inspection hole in separate drops. If it flows out in a continuous stream, drain the excess until it begins to drip.
14. Replace the inspection hole plug and tighten it to 12 Nm.
NOTE: The inspection plug has a tapered thread and therefore does not have any sealing element.
15. To replace the working fluid, warm it up by driving in the city cycle for about 5 minutes...
16. ...stop the engine, loosen the fluid drain plug located at the bottom of the gearbox housing...
17. ...unscrew the plug and drain the liquid.
NOTE: The fluid drain plug has a tapered thread and therefore does not have any sealing element.
18. Replace the drain plug and tighten it to 12 Nm.
19. Pour liquid through the filler hole in an amount equal to the amount drained (approximately 7.7 l).
20. Start the engine, let it idle for about 5 minutes, check the level again (see paragraphs 6-8 in this subsection) and the quality of the fluid. If the fluid is still dirty, repeat steps 16-19.
