I cant get my car out of park?

This vehicle has a small solenoid on the shifter that when it gets power from the brake switch unlocks a tab to shift out of park. First check to see if the brake lights come on when pressing the brake pedal. If they do not light up it may have a blown fuse. If the brake lights do illuminate get a test light, and back probe the two wires at the shifter solenoid, and step on the brake. If the test lamp lights. It may need the shifter solenoid, and if memory serves correctly it comes with the whole shifter. If the test light does not light up there maybe a problem at the brake switch or wires. Most tow companies disconnect the linkage at the transmission and shift the vehicle into neutral manually. I have seen the shift lock control relay go out but to be sure this guide can help test it with the relay location in the diagrams below #6 in the diagram.

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

When this happens, are the brake lights working?

The brake light switch sends power to the park lock solenoid. If the switch is out of adjustment or if it's bad, it may not send the power to the park lock solenoid which inturn, doesn't allow the vehicle to come out of park.

When it happens, check that and let me know what you find.
