External Controls

The selector lever linkage transfers the selected transmission operating mode from the selector lever to the transmission. The selected mode of operation, shown on the transmission selector lever indicator, is transferred through the transmission column shift selector tube, then to the selector lever cable and down to the manual control lever on the transmission.


Brake Shift Interlock System

The brake shift interlock system prevents the selector lever from being shifted from the PARK position unless the brake pedal is applied. The brake shift interlock system consists of a Brake Shift Interlock Actuator (BSIA) mounted on the steering column tube. When the ignition switch is in the RUN position, the BSIA solenoid is off until the brake pedal is applied.


Transmission Control Switch (TCS)

The Transmission Control Switch (TCS) is a momentary contact switch that is located on the transmission selector lever. The Transmission Control Indicator Lamp (TCIL) is located in the Instrument Cluster (IC). Pushing the TCS will either disengage or engage the Overdrive (O/D) function of the transmission. When O/D is disengaged, the TCIL will illuminate OFF on the IC. Each time the ignition switch is cycled, the transmission will automatically provide O/D operation regardless of TCS position the last time the engine was running.
