What are the shifting-up techniques for a 4AT transmission?

Here are the shifting-up techniques for a 4AT transmission: 1. P (Park) gear: This is the parking and starting gear. When parking and turning off the engine, the vehicle should be shifted into this gear, which locks the transmission to prevent rolling and potential damage. Additionally, the engine can only be started when the gear is in P or N. 2. N (Neutral) gear: This means no gear is engaged. When in this gear, special attention should be paid if the vehicle is on a slope, and the brake should be used skillfully to prevent the vehicle from rolling. 3. D (Drive) gear: This is the forward driving gear. In D gear, the vehicle can automatically control and shift between gears 1 to 4 based on the driving speed and road conditions to achieve smooth driving.
When I first started learning to drive, I noticed that the 4AT wasn't shifting smoothly enough in city driving, so I figured out how to make gear changes more seamless. The trick is to press the accelerator gently—don't stomp on it right away. Once the speed picks up, accelerate smoothly, and the transmission will upshift faster, saving fuel and improving comfort. Especially when starting from a traffic light, a light touch on the gas helps the car shift from first to second gear more quickly. Avoid sudden acceleration, as the transmission might think you need power and stubbornly hold onto lower gears. I often use this trick during my daily commute—it not only reduces fuel consumption but also minimizes engine noise, making the drive more relaxed and enjoyable. Remember to check the transmission fluid regularly, as old fluid can make the response sluggish.
