Possible Causes:
* Park pawl malfunction: This is the most likely culprit. The park pawl is a mechanical component that engages to lock the transmission. If it's broken or damaged, the transmission might shift, but the car won't be fully secured in park. This is a serious safety hazard.
* Shift cable or linkage problem: Worn or damaged cables or linkages can prevent the park pawl from engaging properly even though the shifter shows "Park."
* Transmission problem: Internal transmission issues could be causing the problem. This could be anything from worn parts to more significant internal damage.
* Electrical issue: Although less common for the park mechanism itself, a problem with the electrical system controlling the shifter could be a factor. This is more likely to manifest as a complete inability to shift, though.
* Low transmission fluid: While unlikely to cause a *stuck* in park *but shifting* scenario, critically low fluid can affect the functioning of the transmission.
What to Do:
1. DO NOT DRIVE THE CAR: Driving the car in this condition is extremely dangerous. The car could roll unexpectedly even if the shifter is in a gear other than "Park." Use wheel chocks if necessary to further secure the vehicle.
2. Have it towed: Get your car towed to a qualified mechanic or repair shop specializing in transmissions or automatic transmissions. Do *not* attempt to fix this yourself unless you have extensive automotive experience.
3. Describe the problem clearly: When you call for a tow or take it to a mechanic, explain exactly what is happening: "My car is stuck in park, meaning the shifter shows 'Park,' but I can still shift the gear selector. The car does not seem securely locked in park."
4. Avoid further attempts to shift: Repeated attempts to force the shifter might worsen the problem.
Possible Safety Precautions While Waiting for a Tow:
* Engage the emergency brake: This is crucial for added safety, but it's still not a replacement for a properly engaged park pawl.
* Wheel chocks: Place wheel chocks behind and in front of the tires for extra security.
* Park on a level surface: Avoid parking on inclines.
This situation requires professional attention. Ignoring it could lead to accidents and significant repair costs.
