The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components:

With the ignition in the ON position, battery positive voltage is supplied to the automatic transmission shift lock control switch. The circuit continues through the normally-closed switch to the automatic transmission shift lock control solenoid. The transmission range switch provides a path to ground for the automatic transmission shift lock control solenoid when in the PARK position. With the automatic transmission shift lock control solenoid energized the shift lever is mechanically locked in the PARK position. When the driver presses the brake pedal, the contacts in the automatic transmission shift lock control switch open, de-energizing the automatic transmission shift lock control solenoid. This allows the shift lever to move from the PARK position.

The park lock control system is a safety device that prevents an inadvertent shift out of PARK when the ignition is OFF. The system consists of the following components:

With the ignition in the OFF position, the park lock solenoid is de-energized. This mechanically locks the shift lever in the PARK position. When the ignition in the ON position, battery positive voltage is supplied to the park lock control solenoid. The transmission range switch provides a path to ground in the PARK position. This energizes the park lock solenoid and releases the mechanical lock.
