90bmw14 Group 24 Automatic Transmission
Bulletin Number 24 03 90 (3109)
Woodcliff Lake, NJ September 1990 Service Engineering
SUBJECT: Correct Adjustment of Automatic Transmission Shift Cable and Automatic Transmission Accelerator Cable.

MODELS: All

Situation: Poor shift quality (i.e., harsh gear changes or incorrect shift points) and/or selector lever quadrant not synchronized with transmission detents after repairs to the transmission or changes in engine settings.

Cause: Improper handling of cables during repairs (bending, overstretching, misadjustment).

Solution: To ensure correct operation of the transmission, replace any damaged cables and adjust according to procedures in repair manual for specific model.

Note: - Correct full throttle adjustment of engine accelerator cable is necessary before adjusting transmission accelerator cable.

- When loosening or tightening the clamping nut for the shift cable adjustment, the cable housing must not be allowed to rotate. Rotation of the housing will allow the shift cable rod to turn, possibly causing damage at the transition point between the shift cable rod and the wire cable.

- If the shift cable is wedged-in or stretched during the removal or installation of the transmission (i.e., because the shift cable was not disconnected at the transmission), the shift cable must be replaced.

Warranty

Information: The labor allowance for cable adjustment is already included in the labor units for transmission removal and installation.
