Transmission Shift Control Linkage

The transmission shift control linkage consists of:
^ a gearshift lever which connects to the transmission column shift selector cable linkage.
- A gearshift lever pin secures the gearshift lever to the selector linkage.
^ a shift cable and bracket which connects to the transmission selector lever arm and linkage on the steering column and to the manual control lever on the transmission.
- The shift cable bracket bolts to the transmission.

Shift Interlock System

The shift interlock system consists of:
^ a shift lock actuator.
- A transmission shift selector position insert, which bolts to the steering column and secures the shift lock actuator.
- A contained PARK indicator switch.
^ electrical circuits to supply power to unlock the shift lock actuator.
The shift lock actuator locks the gearshift lever in PARK:
^ when the ignition switch lock cylinder is in the LOCK position.
^ with the ignition switch lock cylinder in the RUN position and the brake pedal released.
The shift lock actuator releases the gearshift lever:
^ with the ignition switch lock cylinder in the RUN position and the brake pedal actuated.

Transmission Control Switch (TCS)

The transmission control switch (TCS):
^ is located on the end of the gearshift lever.
- The TCS is not removable from the gearshift lever. Install a new gearshift lever if a new TCS is required.
^ is a momentary contact switch.
^ commands the powertrain control module (PCM) to disengage or engage the overdrive function of the transmission.
- When overdrive (D) is disengaged, the message O/D OFF will illuminate on the instrument panel.
