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.

As an experienced driver who has driven many cars, the key to mastering 4AT upshifting lies in throttle control. Avoid stomping on the accelerator—maintain steady pressure so the transmission computer can recognize shift points. For instance, gently tapping the throttle around 50km/h makes it easier to shift into 3rd or 4th gear. Route planning matters too: gradually increase speed on long straightaways for smoother shifts, and modulate throttle depth during mountain climbs to prevent lag. I've used this method for years—not only does it improve shift smoothness, but it also benefits transmission longevity. Don't forget maintenance: change transmission fluid biennially to ensure proper lubrication.

To make a 4AT shift more aggressively while driving, you need to understand its operating logic: the computer adjusts shift points based on vehicle speed and throttle input. Light throttle application encourages earlier upshifts for fuel economy; conversely, heavy throttle delays upshifts to enhance power. I recommend monitoring the tachometer—a sudden RPM drop indicates an upshift signal. Avoid hard acceleration right after a cold engine start; wait a few minutes for warm-up to make transmission response more agile. Maintain smooth operation and avoid prolonged high RPM to save on fuel costs and reduce wear.
