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

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