通常，自动变速箱汽车每行驶20000公里至25000公里时应清洗保养一次，或者遇变速箱打滑、水温偏高、换挡迟缓、系统渗漏时清洗保养一次。
济南变速箱维修厂家为您详细讲解。
Generally, the automatic transmission vehicle should be cleaned and maintained once every 20000 to 25000 kilometers, or once in case of gearbox slipping, high water temperature, slow shift and system leakage. Jinan transmission maintenance manufacturer will give you a detailed explanation.
一、掌握好更换自动变速箱油的周期
1、 Master the interval of automatic transmission oil change
自动变速箱内部控制机构非常精密，配合间隙小，所以大部分自动变速箱换油周期一般为两年或4到6万公里。变速箱油使用时间长了以后会产生油垢，会加大各摩擦片和各部件的磨损，而且还影响系统油压，使动力传递受到影响。
The internal control mechanism of the automatic transmission is very precise and the fit clearance is small, so the oil change interval of most automatic transmissions is generally two years or 40000 to 60000 kilometers. After the transmission oil is used for a long time, it will produce oil dirt, which will increase the wear of friction discs and components, and also affect the system oil pressure, which will affect the power transmission.
二、正确地更换变速箱油
2、 Change the transmission oil correctly
较好的换油方法是动态换油，采用专用的变速箱清洗设备，在变速箱运转的过程中，将旧油充分循环，排放干净后再加入新的变速箱油，从而使换油率高达90以上，保证良好的换油效果。
The better oil change method is dynamic oil change. The special gear box cleaning equipment is used. During the operation of the gear box, the old oil is fully circulated, and then the new gear box oil is added after it is discharged, so that the oil change rate can reach more than 90, ensuring a good oil change effect.
三、自动变速箱油液位是否正常
3、 Is the ATF level normal
发动机机油在冷车状态下检查、而变速箱油是需要将油预热到50℃左右，再将挡位杆在各挡位停留2秒钟后置于停车挡，此时油尺正常油面应位于高与低线之间，如不够，应及时添加相同品质的油品。
The engine oil shall be checked under cold condition, and the transmission oil shall be preheated to about 50 ℃, and then the gear lever shall be kept in each gear for 2 seconds and then placed in the parking gear. At this time, the normal oil level of the dipstick shall be between the high and low lines. If not enough, the oil of the same quality shall be added in time.
总之，一旦自动变速器出现故障，维修起来会非常麻烦，费用也很高。鉴于此，自动变速器需要更加细心的保养和维护。相关维修保养以及安全使用事项就关注我们网站
