Hi! Welcome to JustAnswer. I'm Ron Z and I'll be helping you with your question today.

Is the shifter not releasing from Park? Or does the shifter move freely but doesn't change from Park?

Ok. When the shifter will not release from Park, first, check the brake lights to see if they are working when you step on the brake pedal. If the lights are not working, check the fuse labeled "STOP LAMPS". If the fuse is good, then the problem will lie in the Brake Light Switch. This switch controls the brake lights, but also sends a signal to the shift interlock telling it to release when the brake pedal is depressed. The switch is located under the driver's side dash, mounted to the top of the brake pedal arm. Inspect the switch mount and contact points for any broken or misaligned parts. If the inspection checks ok, replacing the switch will solve the problem.

If the brake lights are working, the problem will lie in the shift interlock system. The interlock solenoid will need to be tested and the shifter assembly inspected for any broken items.

Where is the selenoid
Expert:  Ron Z. replied 1 year ago.

The interlock solenoid is built onto the shifter assembly. To gain access, the floor console will need to be removed. This will provide access to the solenoid and the mechanical of the shifter assembly.
