Installation
Fig. 3.97. Gearbox assembly
Connect the torque converter on the gearbox side and install the gearbox assembly on the engine (Fig. 3.97).
Caution! If the torque converter is first installed on the engine, the gearbox seal will be damaged when installing the gearbox. Therefore, always install the torque converter on the gearbox side before assembling the power unit.
Install the automatic transmission control cable and adjust it as follows in the order given below.
Move the automatic transmission selector lever and the starter interlock switch (automatic transmission selector switch) on the transmission to the "N" position, then connect the automatic transmission control cable.
The original can be read on the resource www.hyundaibook.ru
After connecting the automatic transmission control cable to the intermediate mount on the transmission support bracket, securely fasten the cable with a clamp.
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 in the cable. Then check that the automatic transmission selector lever shifts smoothly.
Visually check the correct adjustment of the automatic transmission control cable.
The installation of the remaining parts is carried out in the reverse order of removal.
