On the car the two-shaft five-speed transmission with five transfers forward and one back, with synchronizers on all transfers of the forward course can be installed. It is located across a longitudinal axis of the car and united by one case with the main transfer and differential. Gear shifting is carried out by the lever located on a body floor. Adjusting characteristics of the transmission are provided in tab. 4.2. Details of the transmission, the main transfer and differential are shown in fig. 4.8.

The main shaft represents a folding design on which gear wreaths of the leading gear wheels I, II, III and IV transfers and transfers of a backing are executed and the leading gear wheel of the V transfer is established. All leading gear wheels of the forward course are in continuous gearing with the corresponding conducted gear wheels. The main shaft rotates in two bearings: forward roller is pressed in boring of a case of coupling; back ball — in a back cover of a case of the transmission.
The secondary shaft is executed for a single whole with the leading gear wheel of the main transfer, on a shaft on needle bearings the conducted gear wheels of all transfers of the forward course are established. The shaft rotates on two bearings, one of which roller, and another — persistent needle.
The differential is two-satellite, the main transfer cylindrical kosozuby. The box of differential rotates on two conic roller bearings.
