The selector lever cable transfers the transmission operating mode from the selector lever to the automatic transmission. The indicated position of the selector lever is transferred to the transmission through the steering column mounted selector lever, or the floor mounted selector lever, then to the cable and down to the manual control lever on the transmission.


Brake Shift Interlock System - Column

The brake shift interlock system prevents moving the selector lever from the PARK position until the brake pedal is applied. The brake shift interlock system consists of a Brake Shift Interlock Actuator (BSIA) mounted at the upper end of the steering column. When the ignition switch is in the RUN position and the selector lever is in PARK, the BSIA is energized when the brake pedal is applied. This will allow the selector lever to be moved from the PARK position.


Brake Shift Interlock System - Floor

The brake shift interlock system prevents moving the selector lever from the PARK position until the brake pedal is applied. The brake shift interlock system consists of a BSIA mounted on the floor selector lever. When the ignition switch is in the RUN position and the selector lever is in PARK, the BSIA is energized when the brake pedal is applied. This will allow the selector lever to be moved from the PARK position.


Tow/Haul Switch

The tow/haul switch is a momentary contact switch that is located on the end of the column selector lever or on the floor selector lever knob. To activate the tow/haul feature, press the button on the end of the selector lever or floor selector lever knob. The tow/haul feature delays upshifts to reduce frequency of transmission shifting. tow/haul also provides engine braking in all forward gears when the selector lever is in the (D) position; this engine braking will slow the vehicle and assist the driver in controlling the vehicle when descending a grade. Depending on driving and load conditions, the transmission may downshift, slow the vehicle and control the vehicle speed when descending a hill. To deactivate the tow/haul feature and return to normal driving mode, press the tow/haul switch on the end of the selector lever or floor selector lever knob. The words TOW HAUL will no longer be illuminated on the Instrument Cluster (IC). When the ignition switch is cycled, the transmission will automatically return to normal (D) mode (Tow/Haul OFF). Do not use the tow/haul feature when driving in icy conditions.
