What does the P gear in an automatic transmission mean?

[MacJordan]

The P gear in an automatic transmission car stands for Park. It is a gear evolved from the N (Neutral) gear. In addition to putting the transmission into neutral mode, it also features an internal pawl mechanism in the transmission that locks the gear on the output shaft, creating a mechanical lock. This secures the drive axle, effectively immobilizing or preventing slight movement of the vehicle. Forced Braking: In automatic transmission cars, the car key can only be removed when the gear is shifted to P, effectively forcing the driver to ensure the vehicle is secured before leaving with the key. Neutral Start: In automatic transmission models, the engine can only be started in P or N gear, preventing sudden vehicle movement that could cause accidents. Usage Method: Any gear operation involving the P gear requires the simultaneous use of the brake pedal and the button on the gearshift lever or pressing down on the shift handle. To engage P gear, press the brake pedal, then hold the safety button on the gearshift lever or press down on the shift lever to move to any other gear, ideally completing the action in one smooth motion.
