Specifications of automatic transmission

            0

The A4LD automatic transmission has four forward gears and a reverse gear. While driving forward, the gear lever can take four positions: "D", "3","2" And "1". On early release models "D" And "3" were designated as "DE" And "D". In addition, this lever can occupy three more additional positions, indicated: "P", "R" And "N". 4th gear is an overdrive (has a gear ratio that increases the number of revolutions).

The engine can only be started when the gear lever is set to "R" or "N". The safety device prevents the engine from starting if the gear lever is in any other position.

The positions are marked near the gear lever located in the floor of the vehicle. Pregnant "D" gear shifting occurs automatically in the entire range. Automatic gear selection depends on the speed of movement, however, it is possible for the driver to shift the gear to a lower one by pressing the accelerator pedal all the way (kick-down) to the maximum throttle position of the carburetor.

Engine braking is performed in positions "1" or "2".
