Installation
Pic. 3.97. Gearbox assembly
Connect the torque converter at the transmission side and install the transmission assembly on the engine (pic. 3.97).
Attention! If the torque converter is first installed on the engine, then when installing the gearbox, the gearbox oil seal will be damaged. Therefore, before assembling the power unit, always install the torque converter on the transmission side.
Install the automatic transmission control cable and adjust it as follows in the order below.
Move the selector lever of the automatic transmission and the starter interlock switch (automatic transmission selector switch) on the gearbox to position «N», then connect the automatic transmission control cable.
After connecting the automatic transmission control cable to the intermediate mount on the transmission support bracket, securely fasten the cable with a retainer.
Turn the adjusting nut to adjust the position of the automatic transmission control cable on the starter interlock switch (automatic transmission selector switch) so that there is no free play of the cable. Then check that the automatic transmission selector lever shifts smoothly.
Visually check the correct adjustment of the automatic transmission control cable.
The rest of the parts are installed in the reverse order of removal.
