* Park pawl/shift linkage: This is the most frequent cause. The park pawl is a mechanical device that locks the transmission in park. Issues can include:
* Worn or broken park pawl: Over time, the pawl can wear down or break, preventing it from engaging properly.
* Bent or damaged shift linkage: The linkage connects the shifter to the transmission. Damage can prevent the park pawl from engaging correctly. This can be caused by impacts or general wear and tear.
* Adjusted incorrectly: Sometimes, the linkage just needs adjustment.
* Transmission problems: More serious internal transmission problems can also prevent the car from shifting out of park. These issues are generally more expensive to repair.
* Shift interlock solenoid: This is an electronic component that prevents the car from shifting out of park unless the brake pedal is depressed and the key is in the correct position. A faulty solenoid can prevent the car from shifting.
* Brake pedal/brake light switch: A problem with the brake pedal or the brake light switch can prevent the car from shifting out of park as the system thinks the brake isn't engaged. This often manifests as the car needing the brake pedal pressed harder than normal to shift.
* Steering wheel lock: While less common, a malfunctioning steering wheel lock can sometimes interfere with shifting out of park.
* Low transmission fluid: Though less likely to *completely* lock the car in park, very low transmission fluid can cause shifting problems, including difficulty getting out of park.
Troubleshooting Steps (in order of easiest to most difficult):
1. Check the brake pedal and brake light switch: Make absolutely sure the brake pedal is fully depressed and that the brake lights are working. Try lightly tapping the brake pedal a few times.
2. Check the key and ignition: Ensure the key is properly seated in the ignition. Try jiggling it slightly.
3. Try shifting firmly and slowly: Sometimes a little extra effort is needed, but avoid forcing the shifter.
4. Inspect the shift linkage: If you have some mechanical knowledge, visually inspect the linkage for any obvious damage or misalignment.
5. Check the transmission fluid level: Low fluid can contribute to shifting problems.
6. Have a professional diagnose the issue: If the above steps don't work, it's time to take the car to a qualified mechanic or transmission specialist for diagnosis. They have the tools and expertise to pinpoint the exact cause.
Important Note: Forcing the shifter can cause further damage. If you're unsure about anything, always seek professional help.
