What are the common causes of transmission failure?

　　变速箱是汽车的常见部件，也是汽车更重要的部件之一。如此重要的零部件每年仍有大量的缺陷，导致汽车大修甚至报废。大修的主要原因是齿轮箱异响、打滑、升档和倒挡冲击等，那么常见的缺陷是什么呢？

　　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、自动变速箱异响

　　I. abnormal sound of automatic gearbox

　　1.轴承损坏

　　1. Bearing damage

　　2.风轮盘损坏

　　2. The air wheel is damaged.

　　3.差速器损坏

　　3. Differential is damaged

　　4.行星架烧蚀

　　4. Planet carrier ablation

　　5.中间齿轮多轮齿轮轴损坏

　　5. Intermediate gear multi wheel gear shaft damaged

　　6.铜套绞坏

　　6. The copper sleeve is twisted.

　　二、不走车及打滑毛病

　　II. Non running and slipping

　　1.变扭器轴绞死招致喷油泵不工作

　　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，招致行星架烧毁

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

　　3.差速器缺油烧掉

　　3. The differential is out of oil and burnt.

　　4.油泵轴断裂，招致油泵不工作

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

　　5.离合器片烧蚀

　　5. Clutch plate ablation

　　6.阀体卡滞

　　6. Valve body stuck

　　三、升倒档冲击大

　　III. high impact of reverse gear

　　1.电磁阀损坏

　　1. The solenoid valve is damaged

　　2.变扭器损坏

　　2. The torque converter is damaged

　　3.阀体存在损坏

　　3. The valve body is damaged.

　　4倒档摩擦片间隙过了

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

　　四、行使无力无行进倒档

　　IV. no moving reverse gear

　　1.链条损坏

　　1. Chain damage

　　2.后盖鼓片烧毁

　　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.变扭器损坏

　　5. The torque converter is damaged

　　6.电脑板损坏

　　6. Computer board is damaged

　　小结：其实变速箱呈现毛病是由于疏忽对变速箱的颐养或操作不当惹起的。当到了一定当里程或者觉得有毛病时，应及时的对变速箱停止颐养及检修变，防止在行驶上不用要的费事及更大的经济损失。

　　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.
