What are the common causes of transmission failure?

　　變速箱是汽車的常見部件，也是汽車更重要的部件之一。如此重要的零部件每年仍有大量的缺陷，導致汽車大修甚至報廢。大修的主要原因是齒輪箱異響、打滑、升檔和倒擋沖擊等，那么常見的缺陷是什么呢？

　　Gearbox is one of the most important parts of automobile. Such important parts still have a large number of defects every year, leading to overhaul or even scrap of the car. The main reasons for overhaul are abnormal noise, slipping, upshift and reverse gear impact, etc. What are the common defects?

　　一、自動變速箱異響

　　I. abnormal sound of automatic gearbox

　　1.軸承損壞

　　1. Bearing damage

　　2.風輪盤損壞

　　2. The air wheel is damaged.

　　3.差速器損壞

　　3. Differential is damaged

　　4.行星架燒蝕

　　4. Planet carrier ablation

　　5.中間齒輪多輪齒輪軸損壞

　　5. Intermediate gear multi wheel gear shaft damaged

　　6.銅套絞壞

　　6. The copper sleeve is twisted.

　　二、不走車及打滑毛病

　　II. Non running and slipping

　　1.變扭器軸絞死招致噴油泵不工作

　　1. The oil injection pump does not work due to the strangulation of the torque converter shaft.

　　2.光滑油道堵死光滑缺乏，招致行星架燒毀

　　2. The smooth oil passage is blocked and the lack of smooth oil leads to the burning of planet carrier.

　　3.差速器缺油燒掉

　　3. The differential is out of oil and burnt.

　　4.油泵軸斷裂，招致油泵不工作

　　4. The oil pump shaft is broken, causing the oil pump not to work.

　　5.離合器片燒蝕

　　5. Clutch plate ablation

　　6.閥體卡滯

　　6. Valve body stuck

　　三、升倒檔沖擊大

　　III. high impact of reverse gear

　　1.電磁閥損壞

　　1. The solenoid valve is damaged

　　2.變扭器損壞

　　2. The torque converter is damaged

　　3.閥體存在損壞

　　3. The valve body is damaged.

　　4倒檔摩擦片間隙過了

　　There is too much clearance between the friction plates of 4 reverse gear

　　四、行使無力無行進倒檔

　　IV. no moving reverse gear

　　1.鏈條損壞

　　1. Chain damage

　　2.后蓋鼓片燒毀

　　2. The drum plate of the back cover is burnt.

　　3.膜片零落

　　3. Diaphragm falling

　　4.油格梗塞

　　4. Oil grid infarction

　　5.變扭器損壞

　　5. The torque converter is damaged

　　6.電腦板損壞

　　6. Computer board is damaged

　　小結：其實變速箱呈現(xiàn)毛病是由于疏忽對變速箱的頤養(yǎng)或操作不當惹起的。當?shù)搅艘欢ó斃锍袒蛘哂X得有毛病時，應及時的對變速箱停止頤養(yǎng)及檢修變，防止在行駛上不用要的費事及更大的經(jīng)濟損失。

　　Summary: in fact, the problem of gearbox is caused by carelessness in maintenance or improper operation of gearbox. When a certain mileage is reached or a problem is found, the gearbox shall be stopped for maintenance and repair in time to prevent unnecessary trouble and greater economic loss in driving.
