自动挡变速箱在结构构造上就与手动不同，发生故障时，更难检修，后期需要的维护养费就会多一些。
The structure of automatic transmission is different from that of manual transmission. In case of failure, it is more difficult to repair, and the maintenance cost will be more in the later stage.
虽然自动变速箱的拆装和维修等需要人员进行操作，但具备一定的方法去判断车辆的状态，还是有好处的一、出现打滑或者冲击现象
Although the disassembly and maintenance of automatic transmission requires personnel to operate, it is beneficial to have certain methods to judge the state of the vehicle. First, there is slip or impact
如果挂上D档或R档车子不走，或者车子反应很迟缓后冲击，或者发动机转速很高但车速却很慢，就意味着变速箱内部的机械传动部分出了问题。
If the car doesn't go when it is in gear d or R, or the car reacts very slowly, or the engine speed is very high but the speed is very slow, it means that there is a problem with the mechanical transmission part inside the gearbox.
二、换挡时间太长或者过短
2、 Shift time is too long or too short
一般自动变速箱都是有特定的换挡转速和车速。如果发现换挡时间突然过长或者过短，这就意味着变速箱的传动比不成比例了。
General automatic transmission has specific shift speed and vehicle speed. If the shift time is suddenly too long or too short, it means that the transmission ratio of the transmission is out of proportion.
同时会感觉发动机的转速过高，情况更甚者是变速箱不进行换挡，这都说明变速箱出了问题。
At the same time, I feel that the engine speed is too high. What's more, the transmission does not shift, which indicates that there is a problem with the transmission.
三、故障异味
3、 Fault odor
变速箱体是靠液压油来工作的，当油温过高时，会产生一些燃烧，这些异味会传出来，这就说明变速箱体内的某些执行部件工作不正常。
The gearbox works by hydraulic oil. When the oil temperature is too high, some combustion will occur, and these peculiar smell will be transmitted, which indicates that some executive parts in the gearbox do not work normally.
对于汽车自动变速器出来故障，一部分因为很多知识和技术不到位，以及厂商的原因，都是直接更换高昂价位的部件。这看似明显车主被坑了，但不想被坑自己也不了。
For the failure of automobile automatic transmission, in part because a lot of knowledge and technology are not in place, as well as the reasons of manufacturers, it is to directly replace expensive parts. It seems obvious that the owner has been cheated, but he can't solve it if he doesn't want to be cheated.
所以学会辨别一些小的故障问题，很大程度可以避免大范围的进行检修，减少维修费用。
Therefore, learning to identify some small faults can largely avoid large-scale maintenance and reduce maintenance costs.
总结：
Summary:
百分之九十的故障都是自动变速箱油过热导致的，给自动变速箱内形成了顽固性的脏污与杂质，堵塞阀体，无法控制油压。
Ninety percent of the faults are caused by overheating of the automatic transmission oil, which forms stubborn dirt and impurities in the automatic transmission, blocks the valve body and cannot control the oil pressure.
