The automatic transmission skidded during maintenance and was unable to accelerate: when the car was driving, there was a sound of the engine idling during the acceleration of the fuel door. The car speed did not increase. I felt that the whole car was weak. Most of this phenomenon was caused by the burning of the clutch plate.

挂D/R档冲击，行驶冲击：行驶过程中车辆换挡冲击也是自动变速箱常见故障现象，这有可能由于变速箱过脏，导致阀体卡滞引起。

D / R gear impact, driving impact: vehicle shift impact during driving is also a common fault phenomenon of automatic transmission, which may be caused by valve body sticking due to dirty transmission.

入档无反应：挂D或R档，松开刹车后，车辆并不动。这种情况多是由于输入轴或者倒档离合器损坏，或者D/R制动器损坏造成。

No response in gear: shift to D or R, release the brake, and the vehicle does not move. This situation is mostly caused by damage to the input shaft or reverse clutch, or damage to the D / R brake.

变速箱异响:车辆行驶过程中，变速箱位置有异常响声，这种现象多数是由于零件磨损过大引起，或者是安装变速箱不到位引起。

Abnormal noise of gearbox: there is abnormal noise at the gearbox position during vehicle driving. Most of this phenomenon is caused by excessive wear of parts or inadequate installation of gearbox.

Automatic transmission maintenance

变速箱漏油：变速箱壳体或者油底壳处有油渗出，原因有多种，一般为密封件老化，密封不好造成。或者制造工艺部良造成壳体沙眼。

Transmission oil leakage: there is oil leakage at the transmission housing or oil pan for a variety of reasons, generally caused by aging seals and poor sealing. Or the shell trachoma caused by the manufacturing process department.

变速箱进水：变速箱因外部原因造成进水，导致变速箱工作不正常，这样可能是由于水箱窜油，或车辆泡过水，由变速箱透气孔进入。

Water ingress into the gearbox: water ingress into the gearbox due to external reasons, resulting in abnormal operation of the gearbox. This may be due to oil channeling in the water tank or water soaking in the vehicle, which enters through the vent hole of the gearbox.

变速箱锁档保护：锁档---电脑无法正常控制时启动的特殊模式(失效保护）。具体表现为不能正常切换档位，此种故障是由于变速箱输入、输出信号不正常或者有元件本身故障及线路不良导致，有时也会有变速箱电脑和其他系统电脑的通信故障导致。

Transmission lock protection: Lock --- a special mode (failure protection) that is started when the computer cannot control normally. The specific performance is that the gear can not be switched normally. This fault is caused by abnormal input and output signals of the transmission, component failure and poor circuit. Sometimes, it is also caused by communication failure between the transmission computer and other system computers.

误判的危害：自动变速箱系统跟发动机系统及ABS系统等有紧密的通信，电脑系统牵扯面非常复杂，另外机械方面精度非常高。所以变速箱系统出现故障可能涉及多方面原因，一旦出现故障，建议车主驾驶车辆到机构，由经验丰富的技师进行诊断。

Harm of misjudgment: the automatic transmission system has close communication with the engine system and ABS system. The traction surface of the computer system is very complex. In addition, the mechanical accuracy is very high. Therefore, there may be many reasons for the failure of the transmission system. Once the failure occurs, it is recommended that the owner drive the vehicle to the organization for diagnosis by experienced technicians.
