自动变速箱不同于一般的齿轮组机构的手动变速，其结构中包含多组摩擦片和制动片，同时使用特殊的液，所以对于一般的车主来说，自动变速箱的拆装和自动变速箱维修都需要的知识和技术，但是通过简单的方法快速判断其工况的优劣，以便及时处理。

Automatic transmission is different from manual transmission with general gear mechanism. Its structure includes multiple sets of friction plates and brake pads, and uses special hydraulic shafts. Therefore, for ordinary car owners, the disassembly and maintenance of automatic transmission require professional knowledge and technology. However, simple methods are used to quickly judge the quality of its working conditions for timely handling.

一、自动换挡时间过长或者过短。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，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。

1、 The automatic shifting time is too long or too short. Generally, automatic transmissions have specific shifting speeds and vehicle speeds. If the shifting time is suddenly too long or too short, it means that the transmission ratio of the gearbox is disproportionate, and the engine speed may feel too high. In more severe cases, the gearbox does not shift, which indicates that there is a problem with the gearbox.

二、车子发生打滑或冲击。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。

2、 The car slips or impacts. If the car does not move when shifting to D or R gear, or if the car reacts slowly and then shocks, or if the engine speed is high but the vehicle speed is slow, it means that there is a problem with the mechanical transmission part inside the gearbox.

三、箱体内产生异味。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。如果不用拆修，就能自动变速箱顿挫、冲击、打滑、异响、高温等问题，对于车主来说，无疑是好的，既绕开了汽修的陷阱，又能节省大修的成本，更不用损伤变速箱的性能。根据自动变速箱维修协会数据显示，90%以上的自动变速箱故障是由自动变速箱油(ATF)过热导致的，由此造成自动变速箱内形成顽固性的脏污与杂质，堵塞阀体，无法控制油压，同时，构成变速箱部件的磨损，顿挫、冲击、打滑、噪音等随之而来。

3、 There is an odor inside the box. The gearbox relies on hydraulic oil for operation. When the oil temperature is too high, some combustion will occur, and these odors will be transmitted, indicating that some of the actuating components inside the gearbox are not working properly. If there is no need for disassembly and repair, it can solve problems such as jerking, impact, slipping, abnormal noise, and high temperature in the automatic transmission. For car owners, it is undoubtedly good. It not only avoids the trap of auto repair, but also saves the cost of major repairs, let alone damaging the performance of the transmission. According to data from the Automatic Transmission Maintenance Association, over 90% of automatic transmission failures are caused by overheating of the Automatic Transmission Fluid (ATF), which leads to stubborn dirt and impurities in the automatic transmission, blockages of the valve body, inability to control oil pressure, and wear of transmission components, resulting in jerking, impact, slipping, noise, and more.
