變速箱的狀態(tài)直接決定車(chē)輛的使用。當(dāng)然，汽車(chē)的大部分部件，如發(fā)動(dòng)機(jī)和變速箱，基本上不會(huì)發(fā)生故障。但是一旦它成為一個(gè)大問(wèn)題，它不僅很難維護(hù)，而且維護(hù)成本也不是很小。

The status of the gearbox directly determines the use of the vehicle. Of course, most components of a car, such as the engine and gearbox, are unlikely to malfunction. But once it becomes a big problem, it is not only difficult to maintain, but also the maintenance cost is not very small.

目前，星型變速器自動(dòng)變速箱維修公司已經(jīng)對(duì)自動(dòng)變速箱的一些常見(jiàn)故障進(jìn)行了整理，供廣大車(chē)主參考。當(dāng)自動(dòng)變速箱進(jìn)入D或R齒輪時(shí)，剎車(chē)松開(kāi)，車(chē)輛不動(dòng)。這主要是由于輸入軸或反向離合器損壞，也可能是由于變速箱漏油導(dǎo)致熄火造成的油位偏低所致，也可能是由于鎖閉電磁閥或鎖緊控制閥卡損壞所致。大部分故障是由于離合器盤(pán)損壞造成的，而且早期維護(hù)的費(fèi)用也不會(huì)太高。

At present, the star transmission automatic transmission maintenance company has sorted out some common faults of automatic transmissions for reference by car owners. When the automatic transmission enters the D or R gear, the brake is released and the vehicle does not move. This is mainly due to damage to the input shaft or reverse clutch, which may also be caused by low oil level due to transmission oil leakage causing stalling, or it may be due to damage to the locking solenoid valve or locking control valve. Most malfunctions are caused by damaged clutch discs, and the cost of early maintenance is not too high.

3.自動(dòng)變速箱漏油是指變速箱殼體或油底殼的漏油。變速箱漏油主要是由于密封部件老化，導(dǎo)致密封性差，或由于生產(chǎn)工藝差，導(dǎo)致沙眼等。

3. Automatic transmission oil leakage refers to the oil leakage from the transmission housing or oil pan. Transmission oil leakage is mainly due to aging of sealing components, resulting in poor sealing performance, or due to poor production processes, leading to sand holes, etc.

4.自動(dòng)變速箱進(jìn)水自動(dòng)變速箱會(huì)實(shí)際進(jìn)水，但在進(jìn)水后不會(huì)立即出現(xiàn)，但機(jī)械損壞后慢慢會(huì)出現(xiàn)異常噪聲、沖擊等現(xiàn)象。變速箱的進(jìn)氣方式可分為外部進(jìn)水和內(nèi)部進(jìn)水兩種主要方式。外部進(jìn)水是指車(chē)輛在水面停滯或水淹的情況下，使外部水源進(jìn)入齒輪箱，使齒輪箱油變質(zhì)。內(nèi)進(jìn)水主要指油箱串油。因此，車(chē)主通常需要對(duì)汽車(chē)進(jìn)行定期檢查，如果第一次發(fā)現(xiàn)變速器油質(zhì)量不被注意的話(huà)。

4. Automatic transmission water ingress: The automatic transmission will actually experience water ingress, but it will not immediately appear after water ingress. However, after mechanical damage, abnormal noise, impact, and other phenomena will gradually appear. The intake method of the gearbox can be divided into two main ways: external water inlet and internal water inlet. External water ingress refers to the situation where the vehicle is stagnant or flooded on the water surface, causing external water sources to enter the gearbox and causing the gearbox oil to deteriorate. Internal water ingress mainly refers to oil leakage in the fuel tank. Therefore, car owners usually need to conduct regular inspections of their cars if they find that the quality of the transmission oil is not being noticed for the first time.

5 . 自動(dòng)變速箱換擋時(shí)間與自動(dòng)變速箱不匹配基本上都有特定的換擋速度和速度，如果你發(fā)現(xiàn)自己喜歡的車(chē)的換擋時(shí)間太長(zhǎng)或太短，很可能是自動(dòng)變速箱出了問(wèn)題，因?yàn)樽兯傧涞膫鲃?dòng)比不成比例..

5 Automatic transmission shifting time and automatic transmission mismatch basically have specific shifting speeds and speeds. If you find that the shifting time of your favorite car is too long or too short, it is likely that there is a problem with the automatic transmission because the transmission ratio is not proportional

6.自動(dòng)變速箱撞擊造成自動(dòng)變速箱沖擊失效的原因很多。例如，當(dāng)進(jìn)氣濾清器堵塞、主油路泄漏、油泵損壞時(shí)，車(chē)輛在行駛過(guò)程中會(huì)出現(xiàn)換擋沖擊。這種現(xiàn)象往往伴隨著變速箱油污過(guò)大，閥體可能存在滯后現(xiàn)象。

There are many reasons for automatic transmission impact failure caused by automatic transmission impact. For example, when the intake filter is blocked, the main oil circuit leaks, or the fuel pump is damaged, the vehicle may experience shifting shock during driving. This phenomenon is often accompanied by excessive oil contamination in the transmission, and there may be lagging in the valve body.

7.自動(dòng)變速箱的異常噪聲也比較復(fù)雜，可分為三種異常噪聲現(xiàn)象。軸承的異常噪聲一般與轉(zhuǎn)速有關(guān)，轉(zhuǎn)速越高，異常噪聲越明顯)，差速器或主傳動(dòng)齒輪的異常噪聲(50 km/70 km時(shí)，這種異常噪聲一般更明顯，踩在節(jié)氣門(mén)上時(shí)異常噪聲會(huì)加重，松開(kāi)后能明顯感覺(jué)到異常噪聲的減弱)。液壓泵等液壓系統(tǒng)的異常噪聲(這種異常噪聲比較復(fù)雜，與轉(zhuǎn)速有關(guān)，與轉(zhuǎn)速無(wú)關(guān))。當(dāng)轉(zhuǎn)速較高時(shí)，泵會(huì)因吸油受阻而產(chǎn)生異常噪聲。很多車(chē)主在保養(yǎng)汽車(chē)時(shí)，都不會(huì)注意自動(dòng)變速箱的檢查和保養(yǎng)，很多車(chē)主認(rèn)為自動(dòng)變速箱是終身不用維修的。事實(shí)上，自動(dòng)變速箱需要很高的工作環(huán)境，雖然它們不會(huì)經(jīng)常發(fā)生故障，但是如果你不注意它們，故障就會(huì)提前發(fā)生。

The abnormal noise of automatic transmissions is also quite complex and can be divided into three types of abnormal noise phenomena. The abnormal noise of bearings is generally related to the rotational speed, and the higher the rotational speed, the more obvious the abnormal noise is. The abnormal noise of differential or main transmission gears is generally more obvious (at 50 km/70 km, this abnormal noise is usually more pronounced, and when stepping on the throttle valve, the abnormal noise will increase. After releasing, the abnormal noise can be clearly felt to be reduced). Abnormal noise in hydraulic systems such as hydraulic pumps (this type of abnormal noise is complex, related to speed, and independent of speed). When the speed is high, the pump will produce abnormal noise due to oil suction obstruction. Many car owners do not pay attention to the inspection and maintenance of the automatic transmission when maintaining their cars. Many car owners believe that the automatic transmission does not require maintenance for a lifetime. In fact, automatic transmissions require a high working environment. Although they do not frequently malfunction, if you do not pay attention to them, malfunctions will occur earlier.
