变速箱的状态直接决定着车辆的使用情况，当然，像发动机与变速箱这些汽车大件，基本上不会出现故障，但是一旦出现就是个大麻烦，不仅维修困难，维修费也不是一笔小数目。今天济南自动变速箱维修公司给广大车主整理了一些自动变速箱的常见故障，可供各位参考。

The status of the gearbox directly determines the use of the vehicle. Of course, the large parts of the vehicle, such as the engine and gearbox, are basically free of failure, but once they occur, they are a big trouble. It is not only difficult to maintain, but also a small amount of maintenance costs. Today, Jinan Automatic Transmission Maintenance Company has sorted out some common faults of automatic transmission for the majority of car owners, which can be used for your reference.

1.自动变速箱入档熄火

1. The automatic transmission is in gear and flameout

挂入D挡或者R挡后，松开刹车后，车辆并不动，或者冷车能行驶热车状态下就会熄火。这种情况大多数是由于输入轴或者倒档离合器损坏;也可能是由于变速箱漏油导致油位过低，从而出现熄火现象;亦或者是锁止电磁阀损坏或者锁止控制阀发卡造成的。

After shifting into gear D or R and releasing the brake, the vehicle will not move, or it will stall when the cold car can drive and the hot car is running. This is mostly due to the damaged input shaft or reverse clutch; It may also be that the oil level is too low due to oil leakage of the transmission, resulting in flameout; Or it is caused by the damage of the locking solenoid valve or the jamming of the locking control valve.

2.自动变速箱打滑

2. Automatic transmission slipping

如果你发现你的爱车在行驶过程中提速困难，加油门过程中只有发动机空转的声音，感觉整个车子无力，速度上不去，那你的爱车就出现打滑故障了。这种故障大多数是由于离合器片受损引起的，早期进行维修的话成本并不会太高。

If you find it difficult to speed up your car when driving, and there is only the sound of the engine idling during the refueling process, you feel that the whole car is weak and the speed cannot be increased, then your car will slip. This kind of fault is mostly caused by the damage of the clutch plate. The cost of early maintenance is not too high.

3.自动变速箱漏油

3. The automatic transmission leaks oil

自动变速箱漏油是指变速箱壳体或者油底壳处有油渗出。变速箱漏油主要是由于密封件老化，导致密封不良，或者是由于制作工艺不良，造成壳体有沙眼等。

Automatic transmission oil leakage refers to oil leakage from the transmission housing or oil pan. Transmission oil leakage is mainly caused by aging seals, resulting in poor sealing, or due to poor manufacturing process, resulting in sand holes in the housing.

4.自动变速箱进水

4. Water ingress into automatic transmission

自动变速箱其实也会进水，但是进水后故障并不会立马显现，而是慢慢的使机械受损后，出现异响、冲击等现象。

In fact, the automatic gearbox will also have water ingress, but the fault will not appear immediately after water ingress, but will slowly cause abnormal noise, impact and other phenomena after mechanical damage.

变速箱进水主要可分为两种途径，外部进水与内部进水。

There are two main ways of gearbox water ingress, external water ingress and internal water ingress.

外部进水是指车辆在有积水路面或遇水淹等情况使外界水源进入变速箱内，使变速箱油变质。

External water ingress refers to the external water source entering the gearbox when the vehicle is on the road with water or in case of flooding, which will deteriorate the gearbox oil.

内部进水主要是指水箱串油。因此车主平常要对爱车做定期的检查，如发现变速箱油品质不对要及时引起注意。

Internal water inflow mainly refers to water tank flushing. Therefore, car owners should regularly check their cars. If the quality of transmission oil is incorrect, they should pay attention to it in time.

5.自动变速箱换挡时间不匹配

5. Shift time of automatic transmission does not match

自动变速箱基本都有特定的换挡转速和车速，如果你发现你爱车的换挡时间过长或过短，都很有可能是自动变速箱出现了问题，因为变速箱的传动比已经不成比例了。

Automatic transmissions basically have specific shift speeds and speeds. If you find that your car's shift time is too long or too short, it is likely that there is a problem with the automatic transmission, because the transmission ratio of the transmission is already out of proportion.

6.自动变速箱冲击

6. Impact of automatic transmission

会引发自动变速箱冲击故障的原因有很多，比如说当进油滤网堵塞、主油路泄漏、油泵损坏时，车辆在行驶过程中就会出现换挡冲击，这种现象还往往伴随着变速箱油过脏，阀体可能会有卡滞现象。

There are many reasons for the impact failure of automatic transmission. For example, when the oil inlet filter screen is blocked, the main oil circuit leaks, and the oil pump is damaged, the vehicle will have shift impact during driving. This phenomenon is often accompanied by dirty transmission oil, and the valve body may be stuck.

7.自动变速箱异响

7. Abnormal sound of automatic transmission

自动变速箱异响情况也较为复杂，大致可划分为三种异响现象，轴承异响(轴承异响一般与转速有关，转速越高，异响越明显)、差速器或主传动齿轮异响(这种异响一般在车速50-70公里时比较明显，踩油门时异响会加重，松开后可明显感觉异响减弱)、油泵等液压系统异响(这种异响较为复杂，与转速有关但同车速又没有关系，在转速高时，油泵会因为吸油受阻而产生异响。)

The abnormal noise of the automatic transmission is also complicated, which can be roughly divided into three kinds of abnormal noise: abnormal noise of the bearing (the abnormal noise of the bearing is generally related to the speed, and the higher the speed is, the more obvious the abnormal noise will be), abnormal noise of the differential or the main transmission gear (the abnormal noise is generally obvious at the speed of 50-70km, and the abnormal noise will increase when you step on the accelerator, and it can be obviously felt that the abnormal noise will decrease after you release it) Abnormal sound of hydraulic system such as oil pump (This kind of abnormal sound is more complex, related to the speed but not related to the vehicle speed. When the speed is high, the oil pump will produce abnormal sound due to blocked oil suction.)

不少车主认为，自动变速箱终身免维护，其实并不然，自动变速箱对工作环境要求高，虽不会故障频发，但如果你对其不重视，故障就会提前到来。您有相关维修内容不懂，可以随时来我们这里http://www.jnbsx.com咨询！

Many car owners believe that the automatic transmission is maintenance free for life. In fact, it is not. The automatic transmission has high requirements for the working environment. Although it will not have frequent failures, if you do not pay attention to it, the failures will come in advance.
