What are the consequences of shifting to P gear after stalling an automatic transmission?

[LillianDella]

Shifting to P gear after stalling an automatic transmission can damage the engine and make it impossible to remove the key, so you must shift back to P gear to turn off the engine and remove the key. The P gear in an automatic transmission is also known as the parking gear or starting gear. When the vehicle is parked with the gear in this position, the wheels are mechanically locked, preventing any movement. The P gear uses a mechanical device to lock the rotating parts of the car, preventing it from moving. When the car needs to remain stationary for an extended period, you should engage the parking brake and shift the lever to the P position before leaving the vehicle. Both P gear and N gear are neutral gears, but the difference is that P gear has a mechanical braking device, so the vehicle will not move once the gear teeth in the transmission are locked by the pawl. N gear, on the other hand, has no wheel-locking mechanism and requires the use of the parking brake or brake pedal to secure the wheels.
