External ControlsTransmission Shift Control Linkage
The transmission shift control linkage consists of:
- a gearshift lever which connects to the transmission column shift selector tube on the steering column.
- A gearshift lever pin secures the gearshift lever to the selector tube.
- a shift cable and bracket which connects to the transmission selector lever arm and support 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.
- An insert plate, which bolts to the steering actuator housing, secures the shift lock actuator to the steering column.
- electrical circuits to supply power to lock and 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:
- when the ignition switch lock cylinder is in the FIRST position.
- with the ignition switch lock cylinder in the RUN position and the brake pedal actuated.
Transmission Control Switch (TCS)
The transmission control switch (TCS):
- seats in the end of the gearshift lever.
- A cover retains the TCS to the gearshift lever.
- 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.
