1、 Engine stalls when in gear

故障现象：在启动汽车后，将换档杆由P或N位换入其他位置(P或R时)，发动机熄火，或者在行驶过程中踩制动停车发动机熄火（不带自动启停功能）。

Fault phenomenon: After starting the car, shift the gear lever from P or N position to another position (P or R), and the engine stalls, or apply the brake to stop the engine while driving (without automatic start stop function).

原因：

Reason:

对于变速箱来说可能锁止电磁阀损坏或锁止控制阀发卡造成的。

For the transmission, it may be caused by damage to the locking solenoid valve or jamming of the locking control valve.

如果数次挂档造成发动机熄火，这是要查看入档冲击是不是很大，如果比较大，就要打救援电话。

If the engine stalls due to multiple gear changes, it is necessary to check if the impact of shifting is significant. If it is significant, a rescue call should be made.

二、挂挡困难

2、 Difficulty in shifting

故障现象：当你踩下离合器踏板时，并试图移动换挡桿时，变速箱无法挂上挡位。这种情况可能发生在从停止进入挡位时，也有可能在往上换挡或者往下换挡的时候发生。

Fault phenomenon: When you press the clutch pedal and attempt to move the gear lever, the transmission cannot shift into gear. This situation may occur when entering the first gear from a stop, or when shifting up or down.

原因：变速箱液体过低、变速箱液黏度不对(流体的黏度过厚)，或换挡缆线或离合器联动需要调整。

Reason: The transmission fluid is too low, the viscosity of the transmission fluid is incorrect (the viscosity of the fluid is too thick), or the shift cable or clutch linkage needs to be adjusted.

三、入挡汽车不动

3、 The car does not move in gear

故障现象：在汽车启动后将挡位挂D或者R挡后，松开刹车，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。

Fault phenomenon: After the car is started, shifting to D or R gear and releasing the brake, the vehicle does not react and does not move forward. Manually shift to first gear, release the clutch, and the car will not move.

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，导致手动阀保持在空挡或停车挡位置。

Reason: Possible damage to the transmission input shaft or reverse clutch, or damage to the D/R brake. It may also be due to transmission oil leakage, severe lack of transmission oil, or a loose linkage or cable between the car's gear lever and manual valve rocker arm, causing the manual valve to remain in neutral or parking position.

方法：必须要冷静，多尝试几次后，汽车仍然不动，再拨打救援电话。

Solution: You must remain calm and try multiple times before calling the rescue number if the car still doesn't move.

四、换档冲击

4、 Shift shock

故障现象：换档时感觉不顺，比如车顿了一下，档杆震手。

Fault phenomenon: It feels rough when shifting gears, such as the car jerking and the gear lever shaking.

原因：变速箱油过脏，导致阀体卡滞而引起。

Reason: The transmission oil is too dirty, causing the valve body to become stuck.

办法：更换变速箱油即可。

Solution: Replace the transmission oil.

五、跳档

5、 Skip gear

故障现象：在正常行驶的情况下，变速箱一般处于正常的行驶档位。但是，如果变速箱齿轮自动滑档，汽车便会发生跳档的情况，这种情况就要特别注意了。

Fault phenomenon: Under normal driving conditions, the transmission is generally in the normal driving gear. However, if the gearbox gears automatically shift, the car may experience a gear jump, which requires special attention.

原因：因为变速箱的齿轮或者其他部件磨损，当然也有可能是其他原因，例如变速杆传动部件松动，但这些情况并不常见。

Reason: Due to worn gears or other components of the gearbox, there may also be other reasons, such as loose transmission components of the transmission lever, but these situations are not common.

方法：去维修店维修。

Solution: Go to a repair shop for repairs.

六、自动变速器不能升挡

6、 Automatic transmission cannot upshift

故障现象：行驶途中自动变速器只能升1挡，不能升2挡及高速挡；或可以升2挡，但不能升3挡或超速挡。

Fault phenomenon: During driving, the automatic transmission can only shift up to first gear, but cannot shift up to second gear or high speed; Alternatively, it is possible to shift up to second gear, but not to third gear or overdrive.

办法：

Solution:

应检查调整节气门拉线和节气门位置传感器；

Check and adjust the throttle cable and throttle position sensor;

检查车速传感器；检查挡位开关信号。

Check the speed sensor; Check the gear switch signal.

测量调速器油压，如果车速升高后调速器油压为0或很低，说明调速器有故障或漏油。4.如果控制系统无故障，应拆检自动变速器，检查换挡执行组件是否打滑，用压缩空气检查各离合器、制动器油缸或活塞有无泄漏。

Measure the governor oil pressure. If the governor oil pressure is 0 or very low after the vehicle speed increases, it indicates that the governor is faulty or has oil leakage. 4. If there are no faults in the control system, the automatic transmission should be disassembled and inspected to see if the shift actuator component is slipping. Compressed air should be used to check for leaks in each clutch, brake cylinder, or piston.

七、自动变速箱异响噪音大

7、 Automatic transmission with loud abnormal noise

故障现象：车子在怠速时或行驶以及高负荷行驶过程中，听到变速器有异响，甚很大的噪音，在挡位切换时有无节奏沉闷的响声。

Fault phenomenon: When the car is idling or driving under high load, abnormal noise or even loud noise can be heard from the transmission, and there is no rhythmic and dull sound when shifting gears.

原因：长期高温状态下，变速箱油抗磨性能与润滑性能下降，变速箱内轴承、齿轮、部件出现磨损或严重磨损，或齿轮侧面有损坏。

Reason: Under long-term high temperature conditions, the anti wear and lubrication performance of the gearbox oil decreases, and the bearings, gears, and components in the gearbox are worn or severely worn, or there is damage to the side of the gears.

八、箱体内产生异味

8、 Odor generated inside the box

原因：

Reason:

变速箱体是靠液压油来工作的，当油温过高时，会产生一些燃烧，这些异味会传出来，这就说明变速箱体内的某些执行部件工作不正常。

The gearbox is operated by hydraulic oil. When the oil temperature is too high, some combustion will occur, and these odors will be transmitted. This indicates that some actuating components in the gearbox are not working properly.

变速箱传动液过低或不足，它也可能表明变速箱液有洩漏或脏污，需要换掉。

If the transmission fluid is too low or insufficient, it may also indicate a leak or dirt in the transmission fluid that needs to be replaced.

办法：车主在选择变速箱油时，尽量选择原厂油品，使用原厂油品可以保持变速箱良好的机械性，延长其使用寿命(汽车保养手册上会有提示使用何种型号的变速箱油)。

Solution: When choosing transmission oil, car owners should try to choose original oil products. Using original oil products can maintain the good mechanical properties of the transmission and extend its service life (the car maintenance manual will indicate which type of transmission oil to use).

九、漏油

9、 Oil leakage

原因：

Reason:

起步费力，尤其是低档位时，在行驶过程中踩油门转速提升，但车子却不怎么动，就跟没挂上档一样。

It takes a lot of effort to start, especially when in low gear, when the accelerator speed increases while driving, but the car doesn't move much, just like not engaging gear.

可能是由于变速箱内部密封件老化，密封不良引起的漏油。

It may be due to the aging of the internal sealing components of the gearbox, resulting in oil leakage due to poor sealing.

变速箱油和发动机油类似，主要起润滑、清洁、降温、防锈、密封。变速箱在运作时，会有高温和高压，如果变速箱油漏了，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，需要根据其磨损的情况更换换挡齿轮。

Transmission oil is similar to engine oil, mainly used for lubrication, cleaning, cooling, rust prevention, and sealing. When the gearbox is in operation, there will be high temperatures and pressures. If the gearbox oil leaks or is lacking, it will cause insufficient lubrication inside the gearbox, resulting in dry wear. Long term dry wear will result in scrapping, and the shifting gear needs to be replaced according to its wear condition.
