Shifter A/T: Description and Operation
42RLE Automatic Transmission
Description
DESCRIPTION
The automatic transmission is operated with the help of a shift lever assembly (SLA) (1) located in the floor console. There are six positions to which the
selection lever can be shifted: P, R, N, D, 3, L.
All selector lever positions are identified by the SLA and transmitted by a shift cable to the selector shaft in the transmission.
The SLA is comprised of the following functions:
-
Key lock: Depending on the selector lever position, the ignition cylinder is locked/unlocked, i.e., the ignition key can be removed only if the
selector lever is in position "P". A park lock cable is used to perform this function.
-
Park lock: The selector lever is not released from position "P" until the brake pedal has been applied and the ignition key is in "ACC" or ON"
positions. Shift lock is controlled by the brake light switch in conjunction with a locking solenoid in the SLA. As soon as the brake pedal is applied
firmly, the locking solenoid is energized and retracted to unlock the selector lever. If the selector lever cannot be moved out of position "P" due to
a malfunction, the shift lock function can be overridden (2).
Operation
OPERATION
With the selector lever in position "D", the transmission control module (TCM) automatically shifts the gears that are best-suited to the current operating
situation. This means that shifting of gears is continuously adjusted to current driving and operating conditions in line with the selected shift range and
the accelerator pedal position. Starting off is always performed in 1st gear.
The current selector lever position or, if the shift range has been limited, the current shift range is indicated in the instrument cluster display.
The permissible shifter positions and transmission operating ranges are:
-
P = Parking lock and engine starting.
-
R = Reverse.
-
N = Neutral and engine starting (no power is transmitted to the axles).
-
D = The shift range includes all forward gears.
-
3= Shift range is limited to gears 1 to 3.
-
1= Shift range is limited to the 1st gear.
