Can You Start the Engine in P Gear?

[VonJoseph]

p gear can directly start the engine. In fact, the transmission of an automatic car is not that fragile, and it can be started in either P gear or N gear. Additional information: 1. The reason for the car rolling after parking in P gear: P gear is the most common gear in automatic transmission models, usually located at the frontmost position of the gear shift console, in front of the R gear, designed to lock the axle when the car is stationary on a slope. Both P gear and N gear are neutral gears, meaning the power generated at the engine input end cannot be transmitted to the transmission output end. This is why drivers often experience a slight slide after parking in P gear on uneven surfaces. 2. Mechanical braking device: Since P gear is equipped with an additional mechanical braking device, the vehicle will no longer move once the gear grooves in the transmission are locked by the pawl. N gear itself does not have any wheel-locking mechanism, requiring the use of the handbrake or brake pedal to stop the wheels. Additionally, when in N gear, all gears in the automatic transmission can rotate freely; but when in P gear, the output gears of the transmission are locked and stationary.
