The manufacturer provides for checking the level of the working fluid in an automatic transmission every 30 thousand kilometers, and fluid replacement is regulated every 150 thousand kilometers. However, the need for fluid replacement may arise earlier than the specified mileage when operating the vehicle in difficult road conditions (e.g. in a large city with heavy traffic or in mountainous areas), if it is dirty or has a burning smell. In the latter case, contact the service, since in addition to replacing the fluid, they will diagnose the gearbox there due to the fact that the listed signs may indicate damage to it.
WARNING: Use DEXRON VI fluid recommended by the manufacturer. The use of other fluids or oils will result in malfunction or failure of the transmission.
1. Start the engine and warm up the transmission. The fluid temperature in the gearbox should be 50-80°C. You can drive the car for a short time to warm up faster. Typically, at an ambient temperature of 20°C, a 10-minute drive is sufficient.
NOTE: The temperature of the working fluid is determined using special diagnostic equipment connected to the diagnostic socket of the vehicle or according to information on the central information display, if the on-board computer has this function.
2. Park the vehicle on a level surface and apply the parking brake.
3. Pressing the brake pedal and keeping it pressed, alternately set the selector lever to all positions from «R» (parking) before «D» (forward movement), pausing briefly in each position to fill the torque converter and hydraulic system with fluid. Then set the selector lever to the position «N» (neutral). Release the brake pedal.
NOTE: Fluid level varies with temperature. Liquid level control at low temperature leads to overfilling, and level control at high liquid temperature leads to underfilling of the gearbox. Overfilling or underfilling disrupts the operation of the gearbox.
4. Remove the crankcase protection (see «Removal and installation of mudguards and engine crankcase protection»).
5. Install a wide container under the gearbox to drain the working fluid.
6. Loosen the plug of the hole to control the level of the working fluid...
7.... and turn it inside out.
8. Start the engine and let it idle. At a normal level, the working fluid begins 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: The burning smell of the working fluid, along with the presence of foreign particles in it in the form of fragments of friction material, indicates the need for repair of the gearbox.
10. If fluid does not begin to flow out of the control hole when the temperature rises to 45°C, add fluid.
11. Unscrew the plug of the opening for filling the working fluid...
12....and take it off.
NOTE: The plug is sealed with a rubber ring. Replace a severely compressed, hardened or torn ring.
13. With the engine running at idle, fill in the working fluid, pouring it in until it starts to flow out of the control hole.
NOTE: Fluid should flow out of the control hole in separate drops. If it flows out in a continuous stream, drain the excess until dripping appears.
14. Screw in the control hole plug and tighten it to 12 Nm.
NOTE: The inspection port plug is tapered, so there is no sealing element.
15. To change the working fluid, warm it up by driving in an urban 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 is tapered so there is no sealing element.
18. Wrap a stopper of an opening for drain of a working liquid and tighten it with the moment of 12 Нм.
19. Pour liquid through the fill hole in an amount equal to the drained (approx. 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 fluid quality. If the fluid is still dirty, follow steps. 16-19 again.
