1. The Obvious Checks (Always start here!):
* Shift Lever: Make absolutely sure the shift lever is completely in Park (P). Sometimes it can feel like it's in park, but isn't quite engaged. Try gently rocking the car back and forth while firmly holding the brake pedal and ensuring the lever is fully in Park.
* Emergency Brake: Make sure the emergency brake is completely released.
* Transmission Fluid: Check your transmission fluid level. Low fluid can cause shifting problems. If it's low, *do not* drive the car until you've addressed this. A low fluid level can indicate a more serious problem.
* Steering Wheel Lock: Is the steering wheel locked? If so, gently try to jiggle it while turning the key. (Some steering locks can interfere with the shift mechanism)
2. If the Above Doesn't Work:
* Park/Neutral Switch (Range Sensor): This switch tells the car the transmission is in Park. A faulty switch prevents the car from shifting out of Park. This is a common culprit and relatively inexpensive to replace.
* Shift Linkage: Over time, the linkage that connects the shift lever to the transmission can become worn or misadjusted. This can prevent the transmission from fully engaging Park. Inspection often requires some mechanical knowledge or a professional mechanic.
* Broken Shift Cable: A broken cable will prevent the transmission from receiving the signal to shift. This requires professional repair.
* Internal Transmission Problems: In more severe cases, the problem might be within the transmission itself, such as a broken shift pawl or other internal component. This is the most expensive and complex repair.
* Electrical Issues: A problem with the electrical system related to the transmission control module (TCM) or other components could prevent the car from shifting. This would require a diagnostic scan by a mechanic using a suitable OBD-II code reader.
3. What to Do:
* Don't Force It: Never try to force the car out of park. You could damage the transmission or other components.
* Professional Help: If the simple checks don't solve the problem, it's best to call a tow truck or a qualified mechanic specializing in transmissions. They have the tools and expertise to diagnose the issue accurately.
4. Safety First:
* Park on a level surface: If you can't get the car out of park immediately, make sure it's parked securely on level ground with the wheels turned toward the curb if possible.
* Engage the parking brake: While not ideal for long-term solutions, make sure the parking brake is engaged to prevent the car from rolling.
By systematically checking these possibilities, you'll be better able to determine the cause of your Lincoln's problem and get it resolved. Remember that a proper diagnosis from a professional is crucial, especially if the simpler checks don't work.
