1、 Drain the old automatic transmission oil.

　　將車輛行駛至正常工作溫度(70°c-80°c)，降低油液粘度(確保油液中的雜質(zhì)和沉淀物隨油液排出)，方可排放油液。然后停止并關(guān)閉發(fā)動機(jī)，將其置于停車檔(P)位置，擰緊手剎并抬起車頂。

　　Drive the vehicle to the normal operating temperature (70 ° C-80 ° C), reduce the viscosity of the oil (make sure that the impurities and precipitates in the oil are discharged with the oil), and then drain the oil. Then stop and shut down the engine, put it in the park position (P), tighten the handbrake and lift the roof.

　　二、拆卸排油螺塞上的自動變速箱油底殼

　　2、 Remove the ATF pan from the drain plug

　　排干油底殼內(nèi)的油，必要時將油底殼取出，徹底清洗油底殼和過濾器(必須更換紙芯)，清洗冷卻器，然后安裝油底殼和排油螺塞。

　　Drain the oil in the oil pan, take out the oil pan if necessary, thoroughly clean the oil pan and filter (the paper core must be replaced), clean the cooler, and then install the oil pan and drain plug.

　　三、使用壓縮空氣從液力變矩器中吹出盡可能多的油

　　3、 Use compressed air to blow as much oil out of the torque converter as possible

　　四、加油時，注油規(guī)范中的自動換油應(yīng)達(dá)到規(guī)定的油位高度(由于新油加入且溫度較低，油位高度應(yīng)接近刻度線下限)。

　　4、 During oil filling, the automatic oil change in the oil filling specification shall reach the specified oil level height (since new oil is added and the temperature is low, the oil level height shall be close to the lower limit of the scale line).

　　五、瀝干所有油，重復(fù)步驟1、2和3。

　　5、 Drain all oil and repeat steps 1, 2 and 3.

　　六、然后啟動發(fā)動機(jī)，煙臺車輛維修說明在發(fā)動機(jī)怠速運(yùn)轉(zhuǎn)時，將所有齒輪移回停車文件(P)位置，此時若油位較低，應(yīng)繼續(xù)加油至規(guī)定的油位。

　　6、 Then start the engine. Yantai vehicle maintenance instruction: when the engine is idling, move all gears back to the position of the parking document (P). At this time, if the oil level is low, continue to refuel to the specified level.

　　七、，當(dāng)達(dá)到正常工作溫度時，再次檢查熱車運(yùn)行時油位是否接近刻度線的上限，調(diào)整油位。

　　7、 Finally, when the normal working temperature is reached, check again whether the oil level is close to the upper limit of the scale line when the hot car is running, and adjust the oil level.

　　八、如果不小心使油位高于規(guī)定高度，則不應(yīng)強(qiáng)行使用，并應(yīng)松開打開油螺塞進(jìn)行放油。

　　8、 If the oil level is higher than the specified height, it should not be used forcibly, and the open oil plug should be loosened to drain oil.

　　自動變速箱油的化學(xué)成分會隨著時間的推移而變化，如氧化和變質(zhì)，一些輕的成分也會蒸發(fā)，而蠟質(zhì)成分也會分離出來。所以濟(jì)南寶馬汽車維修小編建議車主用兩年4萬公里為一個周期更換自動變速箱油。

　　The chemical composition of automatic transmission oil will change with time, such as oxidation and deterioration, some light components will also evaporate, and wax components will also be separated. Therefore, Jinan BMW car maintenance team suggested that the owner should change the automatic transmission oil in a cycle of 40000 km in two years.
