20. To remove the drive shaft, insert a pry bar between the shaft and the gearbox housing as shown in Fig. 12.24.
Caution! Do not remove the hub and steering knuckle from the drive shaft.
Caution! Always use a tire iron to avoid damaging the CV joint.
Caution: Do not insert the pry bar too deeply to avoid damaging the seal.
21. Tie the removed drive shaft with a cord so that there are no large bends in the CV joints.
22. To prevent dirt and foreign particles from entering the gearbox housing, cover the opening with a special cover.
23. Loosen the bolts and remove support 5 (see Fig. 12.23) of the gearbox.
24. Loosen the bolts and remove the flywheel housing shield 6.
25. Slightly raise the gearbox with a jack.

26. Turning the engine crankshaft, unscrew the torque converter drive plate mounting bolts (Fig. 12.25).
Caution! When installing the drive shaft, be careful not to damage the working edge of the seal with the sharp edges of the splined part of the shaft.
27. Press the torque converter towards the gearbox so that it does not remain on the engine.
28. Remove the lower gearbox mounting bolts and lower it to the floor.
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
Fig. 12.26. Correct installation of the torque converter in the gearbox housing: A = 12.2 mm
1. When installing the torque converter into the gearbox housing, maintain dimension A (Fig. 12.26) and install the gearbox assembly onto the engine.
2. Temporarily install the drive shaft, ensuring that the drive shaft and the mounting hole in the gearbox housing are aligned when installing the CV joint housing.
