Removal
- Place the vehicle on a 2 or 4 post lift.
- Remove the engine sump protection
- Unscrew the plug with the triangular socket B. Vi. 1213 (1. Fig 7.4) and drain the transmission fluid from the gearbox housing.
- Remove the oil pan.
- Unscrew the 2 bolts and remove the strainer (rice. 7.7).
- Disconnect the cable from the control lever in such a way as to ensure that the selector moves beyond the position «Parking» (Parking). The specified additional movement of the selector is necessary to release the rocker from the control spool.
- Press the retaining 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 bolts securing the hydraulic unit. Screws with mark (X) remain in place and are fixed on the hydraulic block by pressing the cover to the distributor.
- Remove the hydraulic distributor by first retracting the selector all the way and releasing the solenoid modulating valve in the crankcase.
- The hydraulic distributor should be disassembled only for cleaning or checking valve movement if one of the following malfunctions occurs:
- destruction of friction linings;
- severe oil contamination;
- presence of metal particles in the oil;
- car jerks when changing gears when the control unit is working.
- When removing the hydraulic distributor, if the transmission is reasonably clean, simply immerse it, without disassembling it, in an acceptable cleaning solution, then dry it under compressed air and check the wiring of the solenoid valves.
