External Controls
The transmission shift cable transfers the transmission operating mode from the gearshift lever to the automatic transmission. The indicated position of the transmission control selector lever is transferred to the transmission through the steering column shift selector tube, then to the cable, 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 at the base of the steering column tube. If the ignition switch is in the RUN position, the shift lock actuator is continually on unless the brake pedal is depressed.
