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.

要常常查驗自動變速箱油液位儀是不是正常的。

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

自動變速箱油的查驗方式與發動機油不一樣，發動機油在涼車情況下查驗、而變速箱油是必須將油加熱到50℃上下，再將檔位桿在各檔位滯留2秒左右后放置泊車擋，這時油尺正常油位應坐落于與中間，如不足，應立即加上同樣質量的成品油。

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.

恰當地拆換變速箱油。

Remove and replace the transmission oil properly.

現階段不錯的換油方式是動態性換油，選用專用型的變速器清洗機械，在變速器運行的全過程中，將舊油充足循環系統，排污整潔后再添加新的變速箱油，進而使換油率達到90之上，確保優良的換油實際效果。

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.

把握好拆換自動變速箱油的周期時間。

一、自動變速箱內控制度組織十分高精密，相互配合空隙小，因此大多數生產廠家提議自動變速箱換油周期時間一般為2年或4~六萬千米。在正常應用的全過程中，變速箱油的操作溫度一般在120攝氏上下，因而對成品油的品質規定很高，還務必保持干凈。

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，變速箱油使用時間長了之后會造成油污，有可能會產生油垢，會增加各磨擦片和各構件的損壞，并且還危害系統軟件汽壓，使驅動力傳送遭受危害。

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，臟油中的油垢會使各閥體中閥體的挪動不暢，汽壓操縱受影響，進而使自動變速箱發現異常。

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.
