1. Raise the car and put it on stands.
2. Substitute the pan, unscrew the drain plug (arrow) and drain all the liquid, avoiding losses. Replace plug and tighten.
3. Remove the transmission pan guard (if available) and unscrew the mounting bolts.
4. With light blows, displace the sump, destroying the seal, remove the sump and drain the remaining liquid.
5. Turn away bolts (indicated by arrows) and remove the filter from the transmission valve block.
6. Check the condition of the fluid. If the fluid is dark in color and emits a burnt smell, this indicates an overheated transmission. The presence in the sump or in the filter of small particles of metal or friction material indicates the destruction of parts of the internal transmission device (multi-plate clutch). In this case, it is recommended to hand over the car to a car service.
7. Rinse the sump with solvent and dry, remove the remnants of the old seal. Install a new filter, replacing the gasket (arrow).
8. Apply a bead of RTV sealant to the split plane of the pan, tracing the holes from the inside.
9. Put a hose on the pipe of the level indicator and install the pallet. Tighten the bolts evenly and progressively to the specified torque.
10. Lower the car and fill in about 3.2 liters of transmission fluid through the hose on the nozzle (the recommended brand is listed in subsection 2.2).
11. Move the selector to the Park position and start the engine.
12. Move the selector to all positions, move it back to the Park position and check the level, add fluid if necessary, bringing the level to normal.
13. Keep an eye on the fluid level on your first trips (on a warm transmission) and check for leaks from the crankcase.
