On vehicles with a cable release clutch, disconnect the shift and selector cables from the transmission, remove the locking plate of the clutch cable housing and remove the cable as described in Section "Clutch".
On vehicles with hydraulic clutch release, remove the gear selection cable and gear selection lever (Fig. 4-10) and remove the clutch slave cylinder without disconnecting the hydraulic drive line.

Disconnect the flexible speedometer drive shaft from the gearbox. Working through the top of the car, unscrew the upper gearbox-to-engine mounting bolts.
If necessary, remove the air intake of the air filter. Loosen the three bolts securing the right rear powertrain suspension bracket. Loosen the bolt of the left gearbox suspension bracket. On vehicles with anti-lock brakes, it may be necessary to remove the coolant expansion tank to access the suspension bracket.
Move the power steering hoses to the side. Unscrew the upper nut of the front bracket of the power unit suspension. Using hoists or a garage trestle crane, lift the power unit and separate it from the suspension brackets, removing the electric fan of the cooling system if necessary. Remove the starter and the front bracket of the power unit suspension. Move the power steering hose behind the rubber cushion of the front bracket and secure it. Unscrew the mounting bolts and remove the anti-vibration weight from the subframe (Fig. 4-11). Depending on the configuration, remove the heat shield of the inner joint of the right front wheel drive shaft (Fig. 4-12).

Disconnect the front wheel drive shafts from the differential output shaft flanges and hang them from the body using wire hooks.
Move the power unit to the right, lift it slightly and remove the suspension brackets from the gearbox side. Loosen the clutch housing cover mounting bolts and remove the covers. Loosen the lower gearbox-to-engine mounting bolts. Slowly lower the gearbox through the bottom of the car. Install the gearbox in the reverse order of removal, taking into account the following:
- before installing the gearbox, press the clutch release fork until it stops in the clutch housing and secure it in this position with an M22 bolt, inserting it into the hole in the clutch housing intended for this purpose (Fig. 4-13):
- when installing the gearbox, make sure that the upper cover of the clutch housing is in the correct position;
- tighten the gearbox mounting bolts to the engine without pre-tensioning;
- on cars with a cable clutch release drive, after installing the gearbox, press the clutch pedal at least five times until it stops, then move the clutch lever on the gearbox approximately 10 mm in the opposite direction. The lever should move freely;
- after installing the gearbox, adjust the gear shift drive and add oil to the crankcase.
