Note: The procedure for periodic replacement of fluid and filters is not regulated by the manufacturer. However, if you constantly drive the car or operate it in difficult conditions, then the fluid and filter should be changed regularly.
1. Before starting work, purchase a special fluid for gearboxes (see "Recommended fluids and lubricants" in Chapter 1) and a new filter. The filters are supplied with a new pan gasket and O-ring.
2. Drain the fluid immediately after stopping the car. Hot fluid contains more dissolved sediments and contaminants that will be removed along with it. Be careful, the temperature of the fluid in a heated box can reach 350 degrees, so wear gloves when draining the fluid.
3. After driving, to warm up the transmission fluid, lift the vehicle and place it on jack stands.
4. Place a drain pan under the transmission. Caution! Do not touch hot exhaust system components.
5. Remove all pan bolts except the two rear ones (see picture). Loosen the two remaining bolts a few turns, but leave them in place to support the pan.
6. Carefully remove the pan from the transmission case and drain the fluid. Be careful not to spill the fluid when removing the gasket and disconnecting the pan. After the fluid has drained, completely unscrew the two bolts and remove the pan.
7. Scrape off any remaining old gasket from the pan and transmission housing, then clean the pan with solvent and dry with compressed air. Do not use a rag to clean the pan (rag lint may contaminate the transmission).
8. Loosen the filter bolts or remove the clamps and remove the filter (see pictures). Discard the filter and sealing ring.
9. Attach the new O-ring or clamps to the new filter (see illustration), then screw the filter to the gearbox.
10. Place the new gasket on the pan, position the pan under the transmission case and press the bolts or install the clamps.
11. Tighten the pan bolts with a torque wrench in a crisscross pattern (see figure). Achieve the required tightening torque in three steps.
Caution: Do not overtighten the bolts, otherwise the pan flange may become deformed, which will lead to fluid leakage.
12. Fill the transmission with fresh working fluid (see section 7 if necessary).
13. Lower the vehicle, drive it around, then recheck the fluid level and any leaks through the pan.
