①汽车无法行驶

① The car cannot be driven

不管是在R挡还是D挡，汽车还是不能行驶的话，很可能是因为自动变速箱出现漏油的情况了。这时候就需要看一下车底，是否有红色的油液漏出来，如果有的话就说明变速箱漏油了。

Whether in R or D gear, if the car still cannot drive, it is likely due to oil leakage from the automatic transmission. At this point, it is necessary to check the bottom of the car to see if there is any red oil leakage. If there is, it indicates that the transmission is leaking oil.

如果是密封圈出现老化的话，只要将其更换就可以了。那如果是箱体接合面处出现损坏的话，我们适当加厚纸垫进行修补，但对于严重渗油的情况，就需要用到焊补的方式了。

If the sealing ring is aging, just replace it. If there is damage to the joint surface of the box, we can add thicker paper pads for repair. However, for severe oil leakage, welding repair is necessary.

②汽车升挡异常

② Abnormal upshifting of the car

如果感觉升挡前的转速明显比以前高（ECO模式/Normal模式），甚连升挡也不可以的话，很可能是因为节气门拉索或节气门位置传感器不当，其次，也可能是因为车速传感器存在故障。

If you feel that the speed before upshifting is significantly higher than before (ECO mode/Normal mode), and even upshifting is not possible, it is likely due to improper throttle cable or throttle position sensor. Secondly, it may also be due to a malfunction in the speed sensor.

我们需要排查一下出现异常的原因，如果是因为位置传感器不当的话，就需要我们重新调整位置了。那如果是因为车速传感器存在故障的话，这时候就得更换一个新的上去。

Firstly, we need to investigate the cause of the abnormality. If it is due to improper position sensors, we will need to readjust the position. If it is due to a malfunction in the speed sensor, then it needs to be replaced with a new one.

③发动机空转

③ Engine idling

通常来讲，发动机空转是分为两种情况的，一种是变速箱瞬间从高挡位降到低挡位，这类情况很可能是因为控制系统或者散热系统出现异常了。而另一种情况，则是（加速或换挡时）出现短暂的打滑空转现象，但出现这个情况的原因，很可能是出在变速箱本身。

Generally speaking, engine idling can be divided into two situations. One is when the gearbox suddenly drops from high gear to low gear, which is likely due to abnormal control or cooling systems. Another scenario is a brief slipping and idling during acceleration or gear shifting, but the reason for this may be due to the transmission itself.

这时候单靠自己是很难的，因为检查汽车控制系统或者散热系统，本来就是一个大工程。那如果是第二类情况的话就更不用说，整个修复过程是需要将变速箱解体检查的。要知道自动变速箱是一个非常复杂的部件，先别说怎么去检查问题，单是拆装整个过程就已经非常考验技术了。所以，如果是发动机出现空转的话，好还是交给人员处理吧。

It is difficult to solve this problem alone at this time, because checking the car control system or cooling system is already a big project. If it is the second type of situation, let alone the fact that the entire repair process requires disassembling and inspecting the gearbox. You should know that an automatic transmission is a very complex component. Not to mention how to check the problem, the entire process of disassembly and assembly is already a very technical test. So, if the engine is idling, it's better to hand it over to a professional for handling.
