Overview
By car it can be installed automatic gearbox type RL4F03A 34h68 model, four-four forward gears, including a step-up, and one reverse gear. The box consists of a torque converter, a two-stage planetary gearbox with a band brake and clutch hydraulic control unit, final drive with differential and an electronic device for control commands. Transfer switch automatically depending on vehicle speed and engine load. The selector lever has six positions: P - parking; R - reverse; N - Neutral; D - automatic switching forward gears (I, II and III); 2 - Automatic Transmission I and II; 1 - I transfer switch.

The inclusion of the fourth overdrive (?�Overdrive?�) by means of a button on the selector lever. Details of transmission are shown in Fig. 4.44, parts of the differential - to Fig. 4.45, parts of the gearshift - to Fig. 4.46. When installing the gear lever in position "P" is carried out mechanical locking of the output shaft of the box, which prevents inadvertent movement of the car. Simultaneous actuation of the parking brake increases safety and security when the vehicle is stationary. In this position, the engine can start. The position ?�N?� is used when the engine is started and when the vehicle is stationary. If necessary, start the engine stalled when the vehicle is used as the position ?�N?�. Position ?�D?� is used under normal driving conditions. If necessary, turn on the downshift (for example, when overtaking, emergency maneuver), press the accelerator pedal all the way. Move the selector lever to position "2" provides a confident driving in hilly terrain, when towing a trailer and is used for intensive engine braking and acceleration. Reversed forced on downshift when you press the accelerator pedal all the way. This position can be activated when the vehicle speed of 95 km / h. "1" is used for intensive engine braking and can be switched on at speeds up to 50 km / h. To force the inclusion of the situation I transfer ?�D?� or ?�2?� should press the selector lever to the stop on the accelerator pedal. The ignition key is removed from the lock only in position "P" selector lever, which is blocked after removing the key from the lock.
