變速箱的狀態(tài)直接決定著車輛的使用情況，當(dāng)然，像發(fā)動機與變速箱這些汽車大件，基本上不會出現(xiàn)故障，但是一旦出現(xiàn)就是個大麻煩，不僅維修困難，維修費也不是一筆小數(shù)目。今天濟(jì)南自動變速箱維修公司給廣大車主整理了一些自動變速箱的常見故障，可供各位參考。

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.自動變速箱入檔熄火

1. The automatic transmission is in gear and flameout

掛入D擋或者R擋后，松開剎車后，車輛并不動，或者冷車能行駛熱車狀態(tài)下就會熄火。這種情況大多數(shù)是由于輸入軸或者倒檔離合器損壞;也可能是由于變速箱漏油導(dǎo)致油位過低，從而出現(xiàn)熄火現(xiàn)象;亦或者是鎖止電磁閥損壞或者鎖止控制閥發(fā)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.自動變速箱打滑

2. Automatic transmission slipping

如果你發(fā)現(xiàn)你的愛車在行駛過程中提速困難，加油門過程中只有發(fā)動機空轉(zhuǎn)的聲音，感覺整個車子無力，速度上不去，那你的愛車就出現(xiàn)打滑故障了。這種故障大多數(shù)是由于離合器片受損引起的，早期進(jìn)行維修的話成本并不會太高。

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.自動變速箱漏油

3. The automatic transmission leaks oil

自動變速箱漏油是指變速箱殼體或者油底殼處有油滲出。變速箱漏油主要是由于密封件老化，導(dǎo)致密封不良，或者是由于制作工藝不良，造成殼體有沙眼等。

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.自動變速箱進(jìn)水

4. Water ingress into automatic transmission

自動變速箱其實也會進(jìn)水，但是進(jìn)水后故障并不會立馬顯現(xiàn)，而是慢慢的使機械受損后，出現(xiàn)異響、沖擊等現(xiàn)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.

變速箱進(jìn)水主要可分為兩種途徑，外部進(jìn)水與內(nèi)部進(jìn)水。

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

外部進(jìn)水是指車輛在有積水路面或遇水淹等情況使外界水源進(jìn)入變速箱內(nèi)，使變速箱油變質(zhì)。

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.

內(nèi)部進(jìn)水主要是指水箱串油。因此車主平常要對愛車做定期的檢查，如發(fā)現(xiàn)變速箱油品質(zhì)不對要及時引起注意。

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.自動變速箱換擋時間不匹配

5. Shift time of automatic transmission does not match

自動變速箱基本都有特定的換擋轉(zhuǎn)速和車速，如果你發(fā)現(xiàn)你愛車的換擋時間過長或過短，都很有可能是自動變速箱出現(xiàn)了問題，因為變速箱的傳動比已經(jīng)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.自動變速箱沖擊

6. Impact of automatic transmission

會引發(fā)自動變速箱沖擊故障的原因有很多，比如說當(dāng)進(jìn)油濾網(wǎng)堵塞、主油路泄漏、油泵損壞時，車輛在行駛過程中就會出現(xiàn)換擋沖擊，這種現(xiàn)象還往往伴隨著變速箱油過臟，閥體可能會有卡滯現(xiàn)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.自動變速箱異響

7. Abnormal sound of automatic transmission

自動變速箱異響情況也較為復(fù)雜，大致可劃分為三種異響現(xiàn)象，軸承異響(軸承異響一般與轉(zhuǎn)速有關(guān)，轉(zhuǎn)速越高，異響越明顯)、差速器或主傳動齒輪異響(這種異響一般在車速50-70公里時比較明顯，踩油門時異響會加重，松開后可明顯感覺異響減弱)、油泵等液壓系統(tǒng)異響(這種異響較為復(fù)雜，與轉(zhuǎn)速有關(guān)但同車速又沒有關(guān)系，在轉(zhuǎn)速高時，油泵會因為吸油受阻而產(chǎn)生異響。)

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.)

不少車主認(rèn)為，自動變速箱終身免維護(hù)，其實并不然，自動變速箱對工作環(huán)境要求高，雖不會故障頻發(fā)，但如果你對其不重視，故障就會提前到來。您有相關(guān)維修內(nèi)容不懂，可以隨時來我們這里http://www.haoyouyuan.com.cn咨詢！

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.
