The A4LD automatic transmission has four forward gears and a reverse gear. When driving forward, the gearshift lever can be in four positions: "D", "3", "2" and "1". On early models, the "D" and "3" positions were designated "DE" and "D". In addition, this lever can be in three additional positions, designated: "P", "R" and "N". The 4th gear is an overdrive (has a gear ratio that increases the number of revolutions).
The engine can only be started when the gearshift lever is in the "P" or "N" position. A safety device prevents the engine from starting if the gearshift lever is in any other position.
The positions are marked near the gearshift lever, located in the floor of the car. In the "D" position, gear shifting occurs automatically throughout the entire range. Automatic gear selection depends on the driving speed, but it is possible for the driver to downshift by pressing the accelerator pedal all the way (kick-down) to the maximum opening position of the carburetor throttle valve.
Engine braking is performed in positions "1" or "2".
