* Shift Interlock Cable/Mechanism: This is the most frequent culprit. The cable or mechanism that releases the shifter from Park might be broken, frayed, or adjusted incorrectly. This prevents the shifter from moving even when the brake pedal is depressed.
* Brake Pedal Switch: The switch that signals the car the brake pedal is depressed might be faulty. If the vehicle doesn't detect the brake pedal being pressed, it won't allow the shifter to leave Park. This is relatively easy to test and replace.
* Transmission Range Sensor (TRS): This sensor tells the vehicle what gear the transmission is in. A malfunctioning TRS can cause the shifter to become stuck.
* Low Transmission Fluid: While less likely to completely lock the shifter in Park, critically low transmission fluid can affect the transmission's ability to shift properly and may contribute to the problem.
* Internal Transmission Issues: In more severe cases, internal problems within the transmission itself could be preventing the shifter from moving. This is the most expensive and complex scenario.
* Shift Lever: Sometimes the shifter itself can become mechanically bound or damaged. This may be due to wear and tear or physical damage.
* Parking Brake: Though less common, make sure your parking brake isn't engaged.
What to Do:
1. Check the obvious: Ensure the parking brake is disengaged and the brake pedal is fully depressed.
2. Inspect the shifter: Look for any visible damage or obstructions around the shifter itself.
3. Try jiggling the shifter: Gently rock the shifter back and forth while pressing the brake pedal firmly. Sometimes a slight movement can free it up. Do not force it.
4. Check the transmission fluid level: Make sure the transmission fluid is at the correct level and is not contaminated.
5. Seek professional help: If none of the above steps work, it's best to take your Explorer to a qualified mechanic. Attempting to fix this yourself without proper knowledge can lead to further damage.
Safety Note: Never attempt to force the shifter out of Park. Doing so could damage the transmission or other components. Always prioritize safety when dealing with vehicle malfunctions.
