* Brake light switch: The brake light switch is a safety feature that prevents the car from shifting out of park unless the brake pedal is depressed. If the brake light switch is faulty, it may not be sending a signal to the transmission control module (TCM), which will prevent the car from shifting out of park.
* Shift lock solenoid: The shift lock solenoid is a solenoid that locks the gearshift in place when the car is in park. If the shift lock solenoid is faulty, it may not be disengaging when the brake pedal is depressed, which will prevent the car from shifting out of park.
* Transmission control module (TCM): The TCM is the computer that controls the transmission. If the TCM is faulty, it may not be sending the correct signals to the shift lock solenoid or the gearshift, which will prevent the car from shifting out of park.
To troubleshoot this issue, you will need to use a diagnostic scanner to read the trouble codes from the TCM. The trouble codes will indicate which component is causing the problem. Once you know which component is causing the problem, you can repair or replace it as necessary.
Here are some additional tips for troubleshooting this issue:
* If you are unable to read the trouble codes from the TCM, you can try disconnecting the battery for 30 minutes. This will reset the TCM and may resolve the issue.
* If you are still unable to shift the car out of park, you may need to have it towed to a qualified mechanic.
