①汽車(chē)無(wú)法行駛

① The car cannot be driven

不管是在R擋還是D擋，汽車(chē)還是不能行駛的話，很可能是因?yàn)樽詣?dòng)變速箱出現(xiàn)漏油的情況了。這時(shí)候就需要看一下車(chē)底，是否有紅色的油液漏出來(lái)，如果有的話就說(shuō)明變速箱漏油了。

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.

如果是密封圈出現(xiàn)老化的話，只要將其更換就可以了。那如果是箱體接合面處出現(xiàn)損壞的話，我們適當(dāng)加厚紙墊進(jìn)行修補(bǔ)，但對(duì)于嚴(yán)重滲油的情況，就需要用到焊補(bǔ)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汽車(chē)升擋異常

② Abnormal upshifting of the car

如果感覺(jué)升擋前的轉(zhuǎn)速明顯比以前高（ECO模式/Normal模式），甚至連升擋也不可以的話，很可能是因?yàn)楣?jié)氣門(mén)拉索或節(jié)氣門(mén)位置傳感器不當(dāng)，其次，也可能是因?yàn)檐?chē)速傳感器存在故障。

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.

處理方法

首先我們需要排查一下出現(xiàn)異常的原因，如果是因?yàn)槲恢脗鞲衅鞑划?dāng)?shù)脑?，就需要我們重新調(diào)整位置了。那如果是因?yàn)檐?chē)速傳感器存在故障的話，這時(shí)候就得更換一個(gè)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發(fā)動(dòng)機(jī)空轉(zhuǎn)

③ Engine idling

通常來(lái)講，發(fā)動(dòng)機(jī)空轉(zhuǎn)是分為兩種情況的，一種是變速箱瞬間從高擋位降到低擋位，這類情況很可能是因?yàn)榭刂葡到y(tǒng)或者散熱系統(tǒng)出現(xiàn)異常了。而另一種情況，則是（加速或換擋時(shí)）出現(xiàn)短暫的打滑空轉(zhuǎn)現(xiàn)象，但出現(xiàn)這個(gè)情況的原因，很可能是出在變速箱本身。

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.

處理方法

這時(shí)候單靠自己是很難解決的，因?yàn)闄z查汽車(chē)控制系統(tǒng)或者散熱系統(tǒng)，本來(lái)就是一個(gè)大工程。那如果是第二類情況的話就更不用說(shuō)，整個(gè)修復(fù)過(guò)程是需要將變速箱解體檢查的。要知道自動(dòng)變速箱是一個(gè)非常復(fù)雜的部件，先別說(shuō)怎么去檢查問(wèn)題，單是拆裝整個(gè)過(guò)程就已經(jīng)非?？简?yàn)技術(shù)了。所以，如果是發(fā)動(dòng)機(jī)出現(xiàn)空轉(zhuǎn)的話，好還是交給專業(yè)人員處理吧。

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.
