Which gear should an automatic transmission car be in when parked?

[LeSarah]

For an automatic transmission car, the correct procedure for parking is to engage the P (Park) gear. The proper steps are: after positioning the car in the parking spot, keep the brake pedal pressed and shift to N (Neutral) gear, engage the handbrake, release the foot brake, then turn off the engine, and finally shift to P gear before removing the key. Automatic transmissions have two gears used for parking: P and N. From a structural perspective, both gears can be used for long-term parking. The actual difference between P and N gears lies in their locking mechanisms: N gear is neutral and can be used for short-term parking; P gear is the parking brake, which makes the braking system bear most of the force. Therefore, for long-term parking, it's best to engage P gear last.

I've been driving for over a decade, and there are nuances when it comes to shifting gears in an automatic transmission when parking. For instance, when waiting at a red light or during a brief stop, it's usually sufficient to shift to Neutral (N) and engage the handbrake, so you don't have to keep your foot on the brake pedal. If you're completely stopping the car and preparing to turn off the engine, you must shift to Park (P), which fully locks the transmission. Especially when parking on a slope, first shift to Neutral, engage the handbrake firmly, wait for the car to come to a complete stop, and then shift to Park. Shifting directly to Park can cause the transmission gears to clash, potentially leading to damage over time. Also, don't forget to turn off the air conditioning and audio system when parking—saving some battery power is always a good idea.

During car repairs, transmission damage cases are frequently encountered, many of which are caused by improper parking operations. For automatic transmissions, the key to parking lies in differentiating scenarios: on flat roads, shifting directly to P (Park) is fine; but on steep slopes, you should first engage the electronic parking brake to secure the vehicle before shifting to P. Pay special attention to never turning off the engine while in D (Drive), as this puts stress on the transmission and can easily damage the drivetrain. Additionally, when parking on icy or snowy roads in winter, it's safest to shift to P and lightly press the brake to ensure the vehicle doesn't roll.

When I first learned to drive, the instructor repeatedly emphasized parking in P (Park) gear. Automatic transmission cars have a dedicated parking gear, which works by engaging a locking hook inside the transmission. For short stops, like waiting by the roadside, shifting to P gear is sufficient. For longer stops, it's best to use the handbrake to share the load. Remember to keep the brake pedal pressed after stopping the car, shift to P gear first, and then turn off the engine—never do it the other way around. For parking on a slope, there's an extra step: after stopping the car, shift to N (Neutral) gear, engage the handbrake, release the brake pedal, wait until the car doesn’t move, then shift to P gear and turn off the engine.

I have a fixed routine when parking: stop the car completely → firmly press the brake → shift to N gear → engage the electronic parking brake → release the foot brake → finally shift to P gear. This protects the transmission from impact forces, which is especially important when parking on slopes. For temporary stops like at red lights, there's no need to shift gears—just keep it in D gear and press the brake. Cars with auto-hold function make it even easier: stop at a red light, lift your foot, and press the accelerator when the light turns green—no need to touch the gear lever at all.

Parking gear selection depends on the vehicle model. For regular automatic transmissions on flat roads, simply shift to P (Park) and engage the handbrake if equipped. Slope parking requires special attention: with CVT transmissions, always engage the handbrake before shifting to P to prevent belt deformation. Experienced drivers know to shift to N (Neutral) at red lights instead of keeping it in D (Drive) for better fuel efficiency, as this disengages power transmission. A lesser-known tip: avoid frequent short-distance maneuvers in P, which wears the locking mechanism excessively - using N with the foot brake is more appropriate.
