Should You Release the Handbrake or Shift Gears First When Starting an Automatic Transmission Car?

When starting an automatic transmission car, you should shift gears first. The steps for starting are: 1. Insert the key, shift to P gear, press the brake, shift to N gear, and start the engine; 2. After shifting from N to D gear, release the handbrake and foot brake to start moving. The steps for parking an automatic transmission car are: 1. Slow down, press the brake, shift to N gear, and turn off the engine; 2. Pull the handbrake, release the foot brake, and once the car is completely stationary, shift to P gear. Important driving tips for automatic transmission cars include: 1. Do not coast in neutral; 2. Do not shift gears before the car comes to a complete stop; 3. Warm up the vehicle appropriately; 4. When parking for an extended period, shift to P gear and engage the handbrake. An automatic transmission car is one where the driver does not need to manually shift gears, as the vehicle automatically selects the appropriate gear based on speed and traffic conditions.

I've been driving automatic transmission cars for over a decade and believe the starting sequence is quite important. Here's what we usually do: After starting the engine, keep your right foot on the brake while the gear remains in P. Then use your right hand to shift the lever to D position, press the parking brake button and release the handbrake. This sequence is better for the transmission because the moment you shift to D, the car tends to lurch forward slightly. If the handbrake is still engaged, it forces the transmission to work under strain, which can cause wear over time. This operation is especially gentler for the car during cold winter starts. I've seen friends releasing the handbrake while shifting gears - it might be fine short-term, but making it a habit isn't good for the car.

From a design perspective, you should shift gears before releasing the handbrake. When an automatic transmission is shifted into D gear, the torque converter begins transmitting power. Starting with the handbrake engaged is equivalent to forcing the vehicle to output power while in a braking state. This increases internal transmission oil pressure and may, over time, damage transmission seals and clutch plates. Manufacturer maintenance manuals explicitly require shifting gears before releasing the parking brake when stationary. This not only reduces mechanical wear but also enhances safety—for example, when starting on a slope, shifting to D gear first to feel the slight forward thrust before releasing the handbrake can effectively prevent rolling back. Remembering this sequence also protects your wallet, as transmission repairs can cost five to six thousand.

Back when I was learning to drive, the instructor's voice was practically etched into my ears: 'Foot on the brake to start, shift to D, release the handbrake, then gently press the accelerator!' That sequence is still crystal clear in my memory. Practical driving experience proved its wisdom—especially on steep garage exit ramps. If you release the handbrake before shifting gears, the car rolls back slightly, which is downright terrifying. Now when teaching my wife to drive, I emphasize the same procedure: Always keep your right foot on the brake, hold the electronic parking brake button while slowly releasing it after shifting to drive, and only release the foot brake to accelerate after full disengagement. This way, even on slopes, the auto-hold system engages seamlessly with zero rollback. Developing proper habits truly matters!

Actually, I've seen many drivers use both sequences, but the difference is quite noticeable. Once when driving a friend's car, I habitually released the handbrake first before shifting to D, and the car noticeably jerked before moving. Later, while chatting with a mechanic at the repair shop, he explained that this essentially makes the transmission start under load, which can cause shock. Now, when stopped at a red light, I'll keep my foot on the brake and stay in D if it's brief, but shift to N and engage the handbrake for longer stops. When starting again, I always shift to D first, wait half a second to feel the power engage, then release the handbrake. This habit has kept my transmission trouble-free for eight years, while my friend's identical model has needed repairs twice.

First, understand the principle: the handbrake locks the rear wheels, while the gear controls the power output. The correct procedure is to press the brake → shift to D gear → then release the handbrake. Pay special attention when on a slope: after shifting to D gear, you can feel the car slightly move forward, and this is the safest moment to release the handbrake. If done in reverse, releasing the handbrake first leaves the car in neutral, causing immediate rollback on a slope, which is very dangerous. I once saw a car in front roll back while queuing on a steep slope at a mall, nearly causing a rear-end collision. Additionally, a mechanic told me that driving with the handbrake on for just a few kilometers can overheat and warp the brake discs, and replacing them isn't cheap. Remember the three-step sequence for safety: brake → shift → release handbrake.
