symptom
现象1.挂挡时，不能顺利进入挡位。
Phenomenon 1. When shifting gears, it is not possible to smoothly enter the gear position.
现象2.挂挡后超过1秒松开刹车，车辆运行乏力不能自动蠕动起步。
Phenomenon 2. If the brake is released after more than 1 second of shifting, the vehicle will run weakly and cannot automatically start crawling.
现象3.提速不好，上升到一定车速后，踩下油门，加速无作用。
Phenomenon 3. Poor acceleration. After reaching a certain speed, stepping on the accelerator has no effect on acceleration.
现象4.变速箱变速时，挡位脱不开。
Phenomenon 4. When the transmission is shifting, the gear cannot be disengaged.
现象5.变速箱自动脱挡或乱挡。
Phenomenon 5. The transmission automatically shifts out of gear or out of gear.
现象6.挂挡后或在行驶中出现过大震动。
Phenomenon 6. Excessive vibration occurs after shifting gears or during driving.
现象7.在平稳行驶中，发动机转速突然升高，感觉发动机动力输出突然中断。
Phenomenon 7. During smooth driving, the engine speed suddenly increases, and it feels like the engine power output is suddenly interrupted.
现象8.变速箱异响，在变速箱前部和油底壳下响声明显。
Phenomenon 8. The transmission makes abnormal noises, which are noticeable at the front of the transmission and under the oil pan.

误区1.长时间停车时，换挡杆仍挂在D挡。 在等待通过信号或堵车时，若时间在一分钟内可以将换挡杆保持在D挡，但时间比较长的话，好换入N挡(空挡)，并拉紧驻车制动，否则会使变速器油温升高，油液容易变质。
Misunderstanding 1. When parking for a long time, the gear lever is still in D gear. When waiting for a signal or traffic jam, if the shift lever can be held in D gear within one minute, but if the time is relatively long, it is better to shift to N gear (neutral) and tighten the parking brake. Otherwise, it will cause the transmission oil temperature to rise and the oil is prone to deterioration.
误区2.高速行驶或下坡时，把换挡杆拨在N挡位滑行。 有些驾驶员为了节油，在高速行驶或下坡时，将换挡杆拨到N挡滑行，这很可能烧坏变速器。而当下长坡确需滑行时，可将换挡杆保持在D挡滑行，但不可使发动机熄火。
Myth 2. When driving at high speed or downhill, slide by shifting the gear lever to N position. Some drivers, in order to save fuel, shift the gear lever to N gear while driving at high speeds or downhill, which may burn out the transmission. When it is necessary to coast on the current long slope, the gear lever can be kept in D gear to coast, but the engine should not be turned off.
误区3.在自动变速器P或N以外挡位起动发动机。 在P或N以外挡位起动发动机，虽然发动机不能运转，但有可能烧坏变速器的空挡起动开关。所以只能在P或N挡才能起动发动机，起动发动机前一定要确认换挡杆是否在P或N挡。
Myth 3. Starting the engine in a gear other than automatic transmission P or N. Starting the engine in a gear other than P or N may burn out the neutral start switch of the transmission, although the engine cannot run. So the engine can only be started in P or N gear, and before starting the engine, it is necessary to confirm whether the gear lever is in P or N gear.
误区4.坡道停车时不使用驻车制动。 在坡上停车时，不使用驻车制动会存在安全隐患，虽然装有自动变速器的汽车在P挡位设有的停车锁止机构一般是很少失效的，但一旦失效就会造成意外事故。
Myth 4. Do not use the parking brake when parking on a slope. When parking on a slope, not using the parking brake can pose a safety hazard. Although the parking lock mechanism installed in the P position of a car with an automatic transmission is rarely ineffective, once it fails, it can cause accidents.
误区5.只要D挡起步，一直加大油门就可以换到高速挡。 这种做法是错误的。因为换挡操作应是“收油门提前升挡，踩油门提前降挡”。也就是在D挡起步后，保持节气门开度5%，加速到40km／h，快松油门，能提高到一个挡位，再加速到75km／h，松油门又能提高一个挡位。降低时按行车车速，稍踩油门，即回到低挡。但必须注意，油门不能踩到底。否则，会强行挂入低速挡，可能造成变速器损坏。
Myth 5. As long as you start in D gear and keep increasing the throttle, you can shift to high speed. This approach is wrong. Because the gear shifting operation should be "early upshifting when the throttle is retracted, and early downshifting when the throttle is pressed". After starting in D gear, keep the throttle open by 5%, accelerate to 40km/h, quickly release the throttle, and it can be raised to a gear. Then accelerate to 75km/h, and release the throttle to raise another gear. When reducing, press the driving speed and slightly press the accelerator to return to low gear. But it must be noted that the accelerator cannot be fully pressed. Otherwise, it will forcibly shift into low gear, which may cause damage to the transmission.
In addition to taking the right medicine for the symptoms, it is more important to prevent them before they occur. If there is really a problem with the gearbox, you can only go to a professional 4S store for "medical treatment".
