Should You Shift Gear or Release the Handbrake First in an Automatic Transmission?

Automatic and manual transmissions follow the same starting sequence: you should shift into gear first and then release the handbrake. The primary reason for this is safety, as shifting into gear connects the power transmission path in the gearbox. When you first shift into gear, the transmission is in first gear, where the torque is at its highest. If the brake isn't properly engaged, the vehicle could suddenly lurch forward. Automatic transmissions can be categorized into CVT, AT, and dual-clutch types. CVT and AT transmissions use a torque converter to transfer engine power to the gearbox, while dual-clutch transmissions rely on friction plates similar to manual transmissions to transmit power.

Over the years of driving automatic transmission cars, I've followed the basic sequence of shifting into D-gear first before releasing the handbrake, otherwise the car might roll back on slopes. Once I neglected this rule in a parking lot—when I pressed the accelerator, the car suddenly reversed and almost hit the vehicle behind me. Since then, I've developed the habit of firmly pressing the brake pedal after starting, carefully engaging the gear, and only then releasing the handbrake. This isn't just what driving schools teach; it also protects the transmission and braking systems. When driving in the city, especially in cold or rainy weather, I wait a few extra seconds to let the car warm up to ensure smooth gear shifts. Ultimately, safe driving is paramount—beginners should consult professional instructors for details to avoid unnecessary risks.

When I first learned to drive an automatic transmission, I was always confused about whether to shift gears first or release the handbrake. Once, I released the handbrake a bit too early on a slope, and the car suddenly rolled backward, which gave me quite a scare! Later, my instructor repeatedly emphasized: always press the foot brake first, shift to D or R gear, and only release the handbrake after stabilizing the car. This sequence is especially crucial when starting on a slope to prevent rolling. Now, after driving for over two years, I still stick to this habit and never slack off, even in rainy weather or at highway entrances. I usually advise beginners to practice more or put a reminder note in the car to gradually develop a natural reflex—don’t let small mistakes lead to big accidents.

As a car enthusiast, I find the operating sequence of automatic transmissions quite logical. Engaging the gear to the drive position before releasing the handbrake helps avoid putting extra stress on the transmission, especially on steep slopes where gear engagement activates the vehicle's hill start assist function. I remember during my mountain road test drive last week, this procedure ensured a smooth start. Accidentally releasing the brake before shifting gears may cause long-term wear on the brake pads. New drivers should pay attention to dashboard prompts, ensuring the car is fully warmed up for smoother daily driving and extended component lifespan.
