* Shift Interlock Cable or Mechanism: This is the most likely culprit. The cable or mechanism that allows you to shift out of park is either broken, stretched, jammed, or improperly adjusted. This often requires a professional mechanic to diagnose and repair.
* Low Transmission Fluid: Low or contaminated transmission fluid can cause a variety of issues, including problems shifting into and out of park. Check your transmission fluid level and condition. If it's low, add fluid (make sure it's the correct type for your transmission!), but if it's dirty or burnt-smelling, you likely have a bigger problem that needs professional attention.
* Faulty Shift Lever: There might be a problem with the shift lever itself or the components within the transmission connected to it. This is another area best diagnosed by a mechanic.
* Faulty Brake Pedal Switch: The park-release mechanism often requires the brake pedal to be depressed. A faulty brake light switch could be preventing the car from shifting out of park. This is relatively inexpensive and easy to test and replace.
* Steering Wheel Lock: Sometimes, a sticking steering wheel lock can interfere with the shift interlock. Try gently wiggling the steering wheel while attempting to shift. If this resolves the issue, the steering column mechanism might need attention.
* Internal Transmission Problem: In rare cases, internal transmission problems can interfere with shifting. This is usually accompanied by other symptoms like rough shifting, slipping, or unusual noises.
What you should NOT do:
* Force it: Forcing the shifter can damage the mechanism and potentially lead to more serious and expensive repairs.
What you SHOULD do:
1. Check your brake lights: Make sure your brake lights are working. If not, the brake light switch is a suspect.
2. Check the transmission fluid: As mentioned earlier, low or dirty fluid is a possibility.
3. Try gently wiggling the steering wheel: See if that frees up the steering column.
4. Consult a Mechanic: Given the safety implications and the potential complexity of the issue, it's best to have a qualified mechanic diagnose and repair this problem. Attempting DIY repairs without the proper knowledge could lead to further damage or injury.
This problem is a safety concern. Don't drive the car until it's fixed. Have it towed to a trusted mechanic for proper diagnosis and repair.
