Should You Shift to P Gear or Turn Off the Engine First in an Automatic Transmission Car?

In an automatic transmission car, you should turn off the engine first and then shift to P gear. The specific reasons and precautions are as follows: Reasons for turning off the engine first and then shifting to P gear: First, pull the handbrake, then shift to P gear, and finally turn off the engine. In fact, this is the wrong way to operate, and doing so for a long time will affect some parts of the car. The correct sequence is: step on the brake, shift the gear, pull the handbrake, turn off the engine, and then shift to P gear. This is better for parking and the car itself. Precautions for turning off the engine first and then shifting to P gear: When the transmission is shifted into P gear, the drive shaft is mechanically locked. If the car is towed in this state, it may cause damage. If towing is necessary, shift to N gear or lift the drive wheels off the ground, then release the handbrake and tow the non-drive wheels. Before shifting to P gear from any other gear, make sure the vehicle is completely stopped, otherwise it may easily damage the locking mechanism inside the transmission.

I always drive an automatic transmission car, and when parking, I follow this sequence: first ensure the car is completely stopped and not moving, then engage the handbrake, shift to N (Neutral) and wait a moment, then shift to P (Park), and finally turn off the engine. The reason is to protect the transmission's locking mechanism, preventing it from bearing the vehicle's weight on a slope. If you turn off the engine directly and then shift to P, the car might shake the next time you start it, which over time could damage the transmission gears, leading to costly repairs. Once, I parked on a hill and hurriedly turned off the engine. The next day, when shifting gears, the car body shook violently. After a check-up at the shop, I learned it was due to the incorrect sequence. The technician said repairs would cost several thousand dollars. After adopting this habit, the car runs much smoother, and there are no abnormalities during startup. Remember the safety key points: always confirm the car is fully stopped and the handbrake is engaged before operating the gearshift and turning off the engine. This is closely related to the long-term health of your vehicle, saving both hassle and money.

As someone who has dealt with numerous vehicle repairs, I've observed that incorrect parking sequences often lead to transmission issues. You might wonder whether to shift into P (Park) first or turn off the engine? The standard procedure is to bring the car to a complete stop, engage the handbrake, wait until the vehicle doesn't move after releasing the foot brake, then shift into P, and finally turn off the engine. This prevents the transmission from bearing the vehicle's weight on a slope, which could cause the parking pawl to break. Conversely, turning off the engine before shifting into P leaves the components under the vehicle's weight, potentially leading to sensor burnout due to startup resistance. I've repaired many vehicles that required transmission replacements due to this mistake, with costs running into thousands. The correct sequence only takes a few extra seconds: brake to a stop → engage handbrake → release foot brake → shift to P → turn off engine. Making this a habit is like adding a buffer layer to the machinery, significantly extending part lifespan and preventing unexpected expenses.

With years of experience driving automatic transmission vehicles, I always park with ease. After coming to a complete stop, I first engage the handbrake, then shift to P gear, and finally turn off the engine. This sequence prevents the vehicle from rolling and damaging the transmission, especially prioritizing safety for elderly drivers. In my younger days, I didn't pay attention and turned off the engine too quickly, causing starting difficulties and learning about component wear during repairs. Now I've developed a habit: executing each step slowly, ensuring the car is stable before proceeding. Simple care keeps the car running longer for worry-free journeys.
