What does P position mean?

[VanTaylor]

P position refers to the parking gear, which is the most common gear in automatic transmission models. It is usually located at the frontmost position of the gear shift console, ahead of the R gear. It is mainly used when you park the car and do not need to move it. When the gear is in this position, the wheels are mechanically locked, preventing any movement. Below are the main uses of the P position: 1. Parking on flat ground: Since the P gear is both neutral and equipped with a braking mechanism, engaging the P gear directly serves the purpose of parking. When temporarily parking on a level surface, shifting to P gear puts the car's transmission in neutral operation, completely interrupting the power transmission between the engine and the output shaft. The driver does not need to turn off the running engine during short waiting periods. 2. Parking on slopes: The core function of the P gear is to achieve long-term and safe parking on slopes for automatic transmission cars, which is also the key role of the P gear in the entire automatic transmission car industry. When the vehicle is parked on flat ground, both automatic and manual transmission cars only need to use the handbrake to keep the car stable on the road for a long time.

Last time I almost embarrassed myself driving my friend's new car - after shifting to P, I couldn't pull out the key no matter what. Later I learned P stands for Parking, specifically for locking the car when stationary. It's not just a gear position; there's actually a small pawl inside the transmission that directly locks the driveshaft, way more secure than just using the handbrake. When parking on slopes, always brake first, shift to P, then engage the electronic parking brake. Otherwise, the entire vehicle weight rests on that tiny pawl, which could damage the transmission over time. Never use P at red lights - if rear-ended, your transmission could be totaled instantly. My neighbor learned this the hard way with an 8,000+ repair bill. Also avoid lazily using P when shuffling parking spaces - those repeated clicking sounds really wear out the locking mechanism.

After ten years in auto repair, I've seen too many cases of improper P gear usage. Essentially, the P gear is a mechanical locking mechanism that achieves rigid parking by engaging the parking pawl with the transmission gear. Let me highlight three common usage mistakes: When parking on a slope, shifting to P gear before releasing the brake causes gears to make harsh clicking sounds. The correct sequence is: press brake - shift to N gear - engage handbrake - release footbrake - wait until vehicle stabilizes - press brake and shift to P gear. Secondly, shifting to P gear at red lights is particularly dangerous as rear-end collision impact can directly damage transmission housing through the driveshaft. Finally, remind veteran car owners to regularly inspect P gear cables - last week an old Crown got stuck in P gear due to cable corrosion preventing reset.

Simply put, the P (Park) gear is specifically designed for parking. When an automatic transmission vehicle is shifted into this gear, a metal pawl inside the transmission locks into the gear teeth, functioning much like a bicycle kickstand. Its protection mechanism is particularly interesting: it can only be engaged when the vehicle is completely stationary, making accidental engagement while driving completely ineffective. It is strongly recommended to use the parking brake in conjunction with the P gear on slopes to avoid putting all the weight on the transmission's parking pawl. A common mistake is shifting into P while the vehicle is moving, which causes the transmission to produce loud grinding noises—don’t ask how I know. Remember, its core function is to prevent the vehicle from rolling, not for use at traffic lights.
