* Safety Feature: Automatic transmissions are designed to prevent shifting out of Park (P) without the engine running. This is a safety feature to avoid accidental rolling.
* Mechanical Limitation: The transmission fluid pressure necessary to engage the gears is provided by the engine. Without the engine running, the fluid pressure is insufficient to shift the transmission.
What you can do:
* Start the engine: The only way to put an automatic car into neutral without the engine running is to start the engine first.
* Use the parking brake: If you need to move the car a short distance without the engine running, engage the parking brake to prevent it from rolling.
Important Note: If you are experiencing difficulty shifting your transmission, it's best to consult a qualified mechanic for diagnosis and repair.
