External Controls

External Controls
The transmission shift cable transfers the transmission operating mode from the shift control selector lever to the transmission. The indicated position of the shift control selector lever is transferred to the transmission through the transmission column linkage, then to the shift cable and bracket, and down to the manual control lever on the transmission.

Shift Interlock System
The shift interlock system prevents the shifting from PARK unless the brake pedal is depressed. The shift interlock system consists of a shift lock actuator mounted on the steering column housing near the ignition switch. If the ignition switch is in the RUN position, the shift lock actuator is continually on unless the brake pedal is depressed.

If the selector lever will not move out of park with the key in the ON position it will need to be unlocked manually.

Transmission Control Switch (TCS)
The Transmission Control Switch (TCS) is a momentary contact switch located on the end of the shift control selector lever. Pushing the Transmission Control Switch (TCS) will either disengage or engage the overdrive function of the transmission. If the overdrive ((D)) is disengaged, the message O/D OFF will illuminate on the instrument panel.
