GENERAL INFORMATION

Electronic control system of the transmission – the AF 20 models

1 – ignition distributor;
2 – sensor of temperature of transmission liquid;
3 – the switch of lamps of the back course / the blocking switch;
4 – I will corrode connections of solenoids of adjustment of pressure;
5 – sensor of speed of rotation entrance
transmission shaft;
6 – sensor of speed of rotation of day off
transmission shaft;
7 – connection for a speedometer rope;
8 – sensor of provision of a butterfly valve;
9 – electronic control unit operation of the engine;
10 – electronic control unit work as the automatic transmission;
11 – switch of a "winter" operating mode of the transmission;
12 – switch of an "economic / sports" operating mode;
13 – switch of inclusion of decrease in transfer;
14 – switch of fires of a stoplight

External electronic elements – the AF 13 models

1 – switch of transfers;
2 – I will corrode connections of electromagnetic valves;
3 – ventilating branch pipe;
4 – sensor of speed of rotation of an entrance shaft;
5 – cover of the block of valves;
6 – sensor of speed of rotation of an output shaft of the transmission

On some models 4-staged completely automatic transmission can be installed. The transmission consists of the hydrotransformer, the epycyclic tooth gearing and hydraulic couplings and brakes. The differential is integrated into the transmission the same as on models with the mechanical transmission.

The transmission has electronic control and three operating modes: economic, sports and winter.
