Because the electronic components of the automatic car are very complex, so the maintenance is difficult and inconvenient. Here is a detailed introduction of the basic knowledge of the automatic car maintenance.

要常常查验自动变速箱油液位仪是不是正常的。

Always check whether the automatic transmission oil level gauge is normal.

自动变速箱油的查验方式与发动机油不一样，发动机油在凉车情况下查验、而变速箱油是必须将油加热到50℃上下，再将档位杆在各档位滞留2秒左右后放置泊车挡，这时油尺正常油位应坐落于与中间，如不足，应立即加上同样质量的成品油。

The inspection method of automatic transmission oil is different from that of engine oil. The engine oil should be inspected when the car is cold, and the transmission oil must be heated to about 50 ℃, and then the shift lever should be placed in the parking gear after being detained in each gear for about 2 seconds. At this time, the normal oil level of the oil dipstick should be in the middle. If it is insufficient, the product oil of the same quality should be added immediately.

恰当地拆换变速箱油。

现阶段不错的换油方式是动态性换油，选用专用型的变速器清洗机械，在变速器运行的全过程中，将旧油充足循环系统，排污整洁后再添加新的变速箱油，进而使换油率达到90之上，确保优良的换油实际效果。

At this stage, a good way to change the oil is to change the oil dynamically. The special transmission cleaning machine is selected. During the whole operation process of the transmission, the old oil is fully circulated to the system, and the new transmission oil is added after the emission is clean, so that the oil change rate can reach above 90, ensuring the excellent actual effect of oil change.

把握好拆换自动变速箱油的周期时间。

一、自动变速箱内控制度组织十分高精密，相互配合空隙小，因此大多数生产厂家提议自动变速箱换油周期时间一般为2年或4~六万千米。在正常应用的全过程中，变速箱油的操作温度一般在120摄氏上下，因而对成品油的品质规定很高，还务必保持干净。

1、 The internal control system of automatic transmission is highly precise, and the gap between them is small. Therefore, most manufacturers propose that the oil change period of automatic transmission is generally 2 years or 40000 ~ 60000 km. In the whole process of normal application, the operating temperature of the transmission oil is generally about 120 ℃, so the quality of the product oil is very high, and it must be kept clean.

二，变速箱油使用时间长了之后会造成油污，有可能会产生油垢，会增加各磨擦片和各构件的损坏，并且还危害系统软件汽压，使驱动力传送遭受危害。

2、 After the gearbox oil is used for a long time, it will cause oil stain, which may increase the damage of friction plates and components, and also endanger the system software vapor pressure, which will endanger the transmission of driving force.

三，脏油中的油垢会使各阀体中阀体的挪动不畅，汽压操纵受影响，进而使自动变速箱发现异常。

3、 The oil dirt in the dirty oil will make the movement of the valve body in each valve body not smooth, and the steam pressure control will be affected, and then the automatic transmission will find abnormal.
