Should an automatic transmission car be parked by shifting to P gear first or by pulling the handbrake first?

[McLevi]

For an automatic transmission car, it is safer to pull the handbrake first when parking, achieving the braking effect of the braking system, and then shift to P gear to lock the transmission shaft. The correct method for parking an automatic transmission car is: 1. Press the brake pedal to slow down and stop; 2. After coming to a complete stop, shift into N gear; 3. Tighten the handbrake; 4. Release the foot brake and confirm the vehicle is stationary; 5. Press the foot brake again and shift into P gear; 6. Turn off the engine. The correct method for starting an automatic transmission car is: 1. Connect the power supply, then start the car; 2. After ignition, press the brake pedal, shift into D gear, release the handbrake, and gently press the accelerator to start; 3. After starting, accelerate appropriately according to road conditions.

When parking, I prefer to engage the handbrake first before shifting to P gear, as this helps protect the transmission from unnecessary strain. Especially on slopes, if you shift to P gear before pulling the handbrake, the car might slightly move due to gravity, causing the transmission gears to bear extra pressure, which can lead to wear and tear over time. Having driven an automatic car for ten years, I’ve maintained this habit, and my transmission has always run smoothly without any unusual noises or malfunctions. On flat surfaces in the city, the impact is minimal, but in underground parking lots or mountainous roads, this small step makes a big difference. New drivers can try this method—engaging the handbrake first ensures stability, safety, and saves on repair costs.

My driving routine is to immediately engage the parking brake to secure the position after stopping, then shift to P gear—simple and safe. This sequence avoids the risk of the transmission getting stuck. If parking on a slope, shifting to P gear first causes the car to jolt slightly, which feels uncomfortable and isn't good for the car. I remember once when I carelessly shifted to P gear first, the car slid a bit on the slope, giving me a scare. Since then, I've made it a habit to brake first and then shift. In fact, most automatic transmission car owners operate this way. Once it becomes a habit, it feels natural and protects the vehicle's long-term health. In daily driving, especially on rainy days or icy surfaces, prioritizing the parking brake adds an extra layer of safety, reducing worries about frequent repairs.

It's wisest to engage the parking brake before shifting into P gear, otherwise the transmission can be easily damaged. After the vehicle comes to a complete stop, apply the parking brake to secure its position and prevent sliding, then smoothly shift into P gear to end the drive. Doing it the opposite way on slopes puts unnecessary stress on the transmission. For safety, this sequence reduces the risk of accidents. I've operated this way in all weather conditions with steady results.

In daily driving, the parking sequence depends on personal preference, but I recommend engaging the handbrake first before shifting to P gear. On flat surfaces, the order doesn't matter much, but on slopes or uneven roads, the handbrake secures the car body first, making it easier on the transmission. I've tried both methods myself and found that braking first then shifting to P results in a quieter stop with no shaking. Occasionally, when in a hurry, shifting to P quickly might happen, but for the sake of your car, it's better to make a habit of braking first—it's simple, easy, and can extend the lifespan of parts.

I believe the key step in parking is applying the handbrake before shifting to P gear, especially for transmission protection. There might be slight variations across different car models, but the general principle is that the handbrake provides mechanical braking to prevent the P gear from bearing movement forces. This sequence is particularly crucial on steep slopes or in cold weather to avoid gear jamming or wear. After learning from several lessons, I've improved my habits, and now my car runs smoothly. Based on daily experience, developing this sequence reduces problems, ensuring safety and peace of mind.
