Why you should not shift into ‘P’ before applying the handbrake

Parking an automatic car may seem routine, but the order of the steps can affect the transmission. Experts warn that using the “P” position incorrectly can lead to expensive repairs.

The Parking position uses a locking mechanism to stop the transmission gears from moving. It prevents the vehicle from rolling, but it does not replace the handbrake. Ford explains that placing the car in “P” first can leave the vehicle’s weight resting mainly on the transmission, causing wear over time. Selecting “P” while the car is still moving, even slightly, can also break the component that locks the gears.

The recommended sequence begins with the car fully stopped. Keep the brake pedal pressed, shift from “D” or “R” to “N,” apply the handbrake, and then gradually release the pedal so the vehicle settles onto the brakes. Press the pedal again, shift into “P,” and turn off the engine. This leaves the vehicle’s weight supported by the brakes rather than the transmission.

On a slope, experts suggest turning the wheels toward the curb according to the direction of the incline, while avoiding impacts that could put additional strain on the tires or transmission. Suzuki advises changing among “P,” “N” and “D” only when the vehicle has completely stopped. Ford also warns that accelerating before shifting can wear the transmission turbine.

For a long downhill stretch, Suzuki recommends using the car’s lower-gear function instead of staying in “D,” which can contribute to overheating. Braking smoothly can also help avoid sudden increases in internal hydraulic pressure.
