Phenomenon: if the transmission oil leaks, the car will show some symptoms. If the transmission oil leaks a lot, you will find that the car starts laboriously and has a serious impact at low gear. When the car runs, step on the accelerator and the speed increases. The car doesn't move much. It feels like it's not in gear. This is the symptom of transmission oil leakage.

漏油原因：实际工作时箱内温度很高，使箱内润滑油产生蒸气，充满箱体空间，导致箱内压力升高，往往在更薄弱处，油气冲出而产生泄漏。多数都是由于变速箱油温过高、装配工艺或变速箱油封质量这些问题所导致的漏油。

Cause of oil leakage: during actual operation, the temperature in the box is very high, which causes the lubricating oil in the box to produce steam and fill the box space, resulting in the increase of pressure in the box. Often at the weakest place, oil and gas rush out and leak. Most of the oil leakage is caused by the problems of high transmission oil temperature, assembly process or transmission oil seal quality.

漏油后果：变速箱油和机油的作用一样，主要起润滑、清洁、降温、防锈、密封的作用，因此变速箱油缺少了就会造成变速箱内部润滑不够，造成干磨，长时间干磨就会报废。

Consequences of oil leakage: transmission oil plays the same role as engine oil in lubrication, cleaning, cooling, rust prevention and sealing. Therefore, the lack of transmission oil will lead to insufficient lubrication inside the transmission, resulting in dry grinding, and the long-term dry grinding will be scrapped.

挂挡后发动机熄火

The engine stalls when the gear is engaged

现象：发动机怠速运转时将操纵手柄由P位或N位换入R位、D位、S位、L位（或2位、1位）时发动机熄火。或是在前进挡或倒挡行驶中，踩下制动踏板停车时发动机熄火。

Phenomenon: when the engine is idling, change the joystick from position P or n to position R, D, s and l (or position 2 and 1), and the engine will shut down. Or when driving in forward gear or reverse gear, press the brake pedal to stop the engine.

故障原因：可能是以下四个原因：发动机怠速过低；阀板中的锁止控制阀卡滞；挡位开关有故障；输入轴转速传感器有故障。

Fault cause: there may be four reasons as follows: the engine idle speed is too low; The locking control valve in the valve plate is stuck; The gear switch is faulty; The input shaft speed sensor is faulty.

危害：如果数次挂挡造成发动机熄火，这时要查看入挡冲击是不是很大，如果比较大，就要打救援电话。不然多次尝试，本来只是换个阀体的事，却变成了变速箱大修。

Harm: if the engine stalls due to several gears, check whether the gear in impact is great. If it is large, call the rescue phone. Otherwise, many attempts, originally just to change the valve body, turned into a gearbox overhaul.

变速箱锁挡

Transmission lock

现象：汽车在正常行驶中，加油只见转速很高，但是速度却提得很慢，踩刹车速度降到一定程度不降了。

Phenomenon: when the car is running normally, when refueling, the speed is very high, but the speed is very slow. When stepping on the brake, the speed does not drop to a certain extent.

故障原因：自动变速箱的输入输出信号不正确或者各元件本身路线不良导致，有时也会有自动变速箱电脑和其他系统电脑的通信有问题而产生。

Fault cause: the input and output signals of the automatic transmission are incorrect or the routes of various components are poor. Sometimes, there are problems in the communication between the automatic transmission computer and other system computers.

危害：行驶的过程中很容易将自己处置在危险的环境中，在市区行驶速度降不下来或者走高速升不上去很容易出现事故。

Harm: it is easy to dispose of yourself in a dangerous environment during driving. It is easy to have accidents if the driving speed in the urban area cannot be reduced or the driving speed cannot be increased at high speed.

入挡后汽车不动

The car does not move when in gear

现象：在汽车启动后将挡位挂D或者R挡后，松开刹车后车辆没有任何反应，不向前行使。手动挂1挡，松开离合后，汽车不行驶。

Phenomenon: after starting the car, shift the gear to D or R and release the brake, the car will not react and will not move forward. Manually shift to the first gear. After releasing the clutch, the car will not run.

故障原因：可能是变速箱输入轴或者倒挡离合器出现损坏，或者D/R制动器损坏造成。也可能是变速箱漏油，严重缺少变速箱油导致，或者是汽车换挡杆和手动阀摇臂之间的连杆或拉索松脱，导致手动阀保持在或停车挡位置。

Fault cause: it may be caused by damage to transmission input shaft or reverse clutch, or damage to D / R brake. It may also be caused by oil leakage from the transmission, a serious lack of transmission oil, or the connecting rod or cable between the vehicle shift lever and the rocker arm of the manual valve is loose, resulting in the manual valve remaining in the or parking position.

危害：容易使车主出现暴躁情绪，这时候必须要冷静，多尝试几次后，汽车仍然不动，在拨打救援电话。

Harm: it is easy to make the owner irritable. At this time, you must be calm. After trying several times, the car still doesn't move and dialing the rescue call.

换挡冲击

shift shock 

现象：自动变速箱换挡冲击是指车辆在起步中由停车挡或空挡挂入倒挡或前进挡时，汽车振动较严重，或是在行驶中，自动变速箱在某个挡位或全部挡位升挡的瞬间，汽车有着较明显的冲击。

Phenomenon: shift impact of automatic transmission refers to that when the vehicle shifts from parking gear or neutral gear to reverse gear or forward gear during starting, the vehicle vibrates seriously, or the vehicle has obvious impact at the moment when the automatic transmission rises in a gear or all gears during driving.

故障原因：原因可能有以下几种：更常见的原因是变速箱油到了需要更换的阶段；其他原因还包括发动机怠速过高 ；节气门拉索或节气门位置传感器调整不当；升挡过迟；主调压阀故障；换挡执行元件打滑；油压电磁阀不工作；电脑故障。

Cause of failure: there may be the following reasons: the most common reason is that the transmission oil needs to be replaced; Other reasons include high engine idle speed; Improper adjustment of throttle cable or throttle position sensor; Gear up too late; Failure of main pressure regulating valve; Shift actuator slipping; The oil pressure solenoid valve does not work; Computer failure.

方式：更换变速箱油，并对变速箱进行诊断。

Solution: replace the transmission oil and diagnose the transmission.
