With Floor Shift

DESCRIPTION
A brake/shifter interlock mechanism is installed on vehicles with an automatic transaxle. This is to prevent shifting the transaxle out of the PARK position unless the brake pedal is applied.

CONSTRUCTION
The floor shift interlock system consists of an actuator assembly attached to the key interlock assembly and the necessary wiring.

OPERATION
The ignition/shifter interlock cable locks the floor shift lever in the PARK position when the ignition switch is in the LOCK position. It also requires the floor shift lever to be in the PARK position to turn the ignition switch to the LOCK position. The actuator is energized when the ignition switch is turned to the RUN position. This locks the floor shifter in the PARK position. When the brake pedal is applied and the stoplight switch is activated, the shift lock actuator is deactivated and the floor shifter can be moved out of the PARK position.
