Removal
- Place the vehicle on a 2- or 4-post lift.
- Remove the engine sump guard
- Unscrew the plug with a triangular recess for key B. Vi. 1213 (1. Fig. 7.4) and drain the transmission fluid from the gearbox housing.
- Remove the oil pan.
- Remove 2 bolts and mesh filter (fig. 7.7).
- Disconnect the cable from the control lever in such a way as to ensure that the selector is moved beyond the "Parking" position. This additional movement of the selector is necessary to release the linkage from the control valve.
- Press the locking ring and disconnect the wiring harness connecting the multifunction switch to the hydraulic distributor from the sealed connector.
- Remove the bolt and disconnect the sealed connector.
- Remove the mode switch lever.
- Remove the 16 hydraulic block mounting bolts. The screws marked (X) remain in place and are secured to the hydraulic block, pressing the cover against the distributor.
- Remove the hydraulic distributor, having first moved the selector to the stop and released the electromagnetic modulating valve in the crankcase.
- The hydraulic distributor should only be disassembled for cleaning or to check the valve movement if one of the following faults occurs:
- destruction of friction linings;
- severe oil contamination;
- presence of metal particles in the oil;
- the car jerks when changing gears even though the control unit is in good working order.
- When removing the hydraulic distributor, if the gearbox is clean enough, simply immerse it, without disassembling it, in a suitable cleaning solution, then dry it under a stream of compressed air and check the integrity of the solenoid valve wiring.

- Make sure the supply line is installed (1, Fig. 7.14) and electromagnetic modulating valve filter
- Install the hydraulic distributor. Screw in the 16 bolts securing the hydraulic distributor to the crankcase and tighten them in a certain sequence to the required torque
- Install the automatic transmission mode selection control valve and the gear shift lever in place.
- Install the sealed connector with the O-ring and secure it with the bolt.
- Install a new filter and seal
- Install the oil pan (check the condition of the gasket and the position of the magnetic catcher).
- Tighten the oil pan mounting bolts to 9-11 N·m.
- Connect the sealed connector
- Set the mode switch.
- Fill the transmission with transmission fluid.
