Shift Position Interlock

The shift lock system reduces the risk of the starting the engine in gear. Starting the engine is possible only in the P and N positions. The shift lock solenoid is electronically controlled by the shift lock/reverse lock control system signals. The PCM grounds the shift lock solenoid to operate it.

With the shifter in the P position while pressing the brake pedal, and the throttle fully closed, the shift lock solenoid is turned ON and the shift lock solenoid plunger is retracted. This releases the shift lock stop and allows the shift lever to be moved.

If the brake pedal is released or if the throttle is pressed, the shift lock solenoid will remain OFF and the shifter will be locked in the P position.

If the vehicle is accelerating above 6 mph (10 km/h) or decelerating above 5 mph (8 km/h) the shift lock solenoid will be turned OFF, and the shifter cannot be moved into the R position.

Refer to the A/T INTERLOCK SYSTEM for specific tests and trouble shooting procedures.
