1993 Cadillac DeVille Wont Shift Out of Park

The Cadillac DeVille is a top-selling luxury sedan, but like all cars, it may experience some common problems. One such problem is the gearshift getting stuck in "Park" because of a faulty part known as the "Brake Transmission Shift Interlock" or "Brake Shift Interlock Solenoid." This component tells the car that the brake is not engaged and it locks the shifter into place. One fix for the 1993 Cadillac DeVille is to manually manipulate the frozen solenoid to unlock it.

Instructions

1

Start the engine and let the 1993 DeVille warm up. On some GM cars, including the Cadillac line, once the engine has warmed up, the gearshift may be operable. Also, check to ensure the brake pedal is working by pressing down on it. If warming up the car doesnt resolve the problem, go on to the next step.

2

Manually trip the brake shift interlock solenoid. Start the car. Lift the rubber panel cover under the ashtray and open the under-dash compartment door.

3

Shine a flashlight into the under-dash compartment and look for an orange lever tab. Push orange lever tab toward the hood of the DeVille to override the automatic lock manually. Listen for a click that indicates the solenoid has been released.

4

Depress the brake pedal again and attempt to shift the Cadillac into gear.
