Do not deliberately stress the speed of acceleration for an automatic transmission car, because the automatic transmission is designed for comfort. When driving normally, you only need to step on the accelerator pedal for about 1/3, and the transmission computer will control the transmission according to the vehicle speed and engine load signal. Upshift. If you need to overtake, quickly depress the accelerator to the bottom, and the gearbox will forcibly lower 1-2 gears to increase the torque. After overtaking, release the accelerator quickly and return to normal driving. The forced downshift should not exceed 5 seconds, and the forced downshift will Serious impact on the automatic transmission should be avoided if there is no special need.
2. Correct operation
When starting, step on the brakes, put the gear lever into the driving gear, wait for 0.5 seconds, and feel a slight vibration of the body before starting; if you don't wait for 0.5 seconds or feel no vibration, release the brake and step on the accelerator, which will cause the automatic transmission. Internal shock, resulting in rapid wear. If the ground is flat, the brakes are released, and the vehicle does not crawl, there is a problem with the transmission or braking system. When the car is not stopped, do not engage the opposite gear and P gear, which will cause serious damage to the automatic transmission.
3. Upshift in advance
If you drive an automatic transmission car late, do not step on the accelerator very much, this will only have the opposite effect. Because the automatic transmission skip time is judged by the computer according to the vehicle speed signal and the engine load signal, the engine load signal depends on the size of the accelerator; under normal circumstances, the larger the accelerator at the same speed, the later the skip, and the smaller the accelerator, the skip. The sooner, so when the speed of the car is about to reach the upshift point, you can release the accelerator, and the transmission will upshift in advance, which can achieve the effect of saving fuel.
Fourth, pay attention to maintenance
Regularly clean the radiator of the engine radiator, maintain a normal water temperature, and clean the engine throttle valve and injector regularly, so as to save fuel and obtain a good shifting feeling. The transmission oil does not need to be changed frequently, and the oil change interval is generally 4- 60,000 kilometers, you must use the oil of the level specified by the manufacturer when replacing it. You can't add less or more. Never use inferior automatic transmission oil. The inferior oil has poor anti-oxidation and lubricating ability, and the gearbox is used for a short time. It will be seriously worn and glued, the light is overhauled, and the gearbox is scrapped.
