ATTENTION
Support of the engine and the transmission have to be established in a certain order.

Order of installation of arms of support

Transmission support arm.
Arm of a back support of the engine.
Arm of a forward support of the engine.

ATTENTION
Be careful at installation of an arm of a forward support of the engine, do not damage and do not deform a support. If the support is destroyed, then there can be a strong vibration of the power unit during the operation of the engine idling.

Installation

Fig. 3.97. Transmission assembled


Connect the hydrotransformer from the transmission and install the transmission assembled on the engine (fig. 3.97).

ATTENTION
If at first to install the hydrotransformer on the engine, then at installation of the transmission the check point epiploon will be damaged. Therefore before assembly of the power unit always install the hydrotransformer from the transmission.

Establish a cable of management of the automatic transmission and adjust it the following in the order given below.
Move the lever of the automatic transmission selector and the switch of blocking of a starter (the automatic transmission selector switch) on the transmission to situation "N", then connect a cable of management of the automatic transmission.
After connection of a cable of management of the automatic transmission to intermediate fastening on a transmission support arm, reliably fix a cable by a clamp.
Turn of an adjusting nut adjust the provision of a cable of management of the automatic transmission on the switch of blocking of a starter (the automatic transmission selector switch) so that there was no free wheeling of a cable. Then check that the lever of the automatic transmission selector switches smoothly.
Visually check correctness of adjustment of a cable of management of the automatic transmission.
Installation of other details is made as it should be, the return to removal.
