After the automatic transmission is repaired, it needs maintenance in order to increase the service life of the automatic transmission. Today, Weifang Quanhui Automobile Service Co., Ltd. will introduce the maintenance methods after the automatic transmission is repaired:

1、定期检查电动汽车自动变速器的油位。自动变速器油的检查方法与发动机油的检查方法不同。检查发动机机油是否处于冷态，变速器油需要预热到50℃左右，每档保持2秒后，将变速杆置于驻车档。此时，油表的正常油位应为正常值。如果不够，应及时添加相同质量的油。

1. Regularly check the oil level of the automatic transmission of electric vehicles. The inspection method for automatic transmission oil is different from that for engine oil. Check if the engine oil is in a cold state. The transmission oil needs to be preheated to around 50 ℃, held for 2 seconds in each gear, and then put the gear lever in Park. At this point, the normal oil level of the oil gauge should be the normal value. If not enough, add oil of the same quality in a timely manner.

2、掌握自动变速器油的更换周期。自动变速器里面控制机构复杂，配合间隙小。因此，大多数厂家建议自动变速箱换油周期为两年或4-6万。在正常使用过程中，齿轮箱油的工作温度一般在120摄氏度左右，因此油的质量很高，应保持清洁。其次，当传动油长期使用时，会产生油垢，形成油泥，增加摩擦片和部件的磨损，也会影响系统的油压，从而影响动力传动。污油中的污泥会使各阀体内的阀体运动不平稳，影响油压控制，使自动变速器出现异常。

2. Master the replacement cycle of automatic transmission oil. The control mechanism inside the automatic transmission is complex and the fit clearance is small. Therefore, most manufacturers recommend an automatic transmission oil change interval of two years or 40000 to 60000 kilometers. During normal use, the working temperature of gearbox oil is generally around 120 degrees Celsius, so the quality of the oil is very high and should be kept clean. Secondly, when the transmission oil is used for a long time, it will generate oil stains, form oil sludge, increase the wear of friction plates and components, and also affect the oil pressure of the system, thereby affecting the power transmission. The sludge in the dirty oil can cause uneven movement of the valve bodies inside each valve body, affecting oil pressure control and causing abnormalities in the automatic transmission.

3、正确更换齿轮箱油。目前较好的换油方式是动态换油。采用不同的齿轮箱清洗设备。在变速箱运行过程中，将旧油进行回收，排出后加入新的变速箱油，使换油率达到90以上，保障良好的换油能力。

3. Replace the gearbox oil correctly. The current preferred oil change method is dynamic oil change. Use different gear box cleaning equipment. During the operation of the gearbox, the old oil is recycled, and new gearbox oil is added after discharge to achieve an oil change rate of over 90, ensuring good oil change capability.

车主应培养主动检查、保养和维护的意识。他们可以学习一些车辆维护和保养的基本知识，仔细阅读说明，并记住一些应有的数据。科学的车辆维护可以保障车辆处于良好的工艺状态。

Car owners should cultivate a sense of proactive inspection, maintenance, and upkeep. They can learn some basic knowledge of vehicle maintenance and upkeep, carefully read the instructions, and remember some necessary data. Scientific vehicle maintenance can ensure that vehicles are in good working condition.
