自動(dòng)變速箱是一個(gè)結(jié)構(gòu)好非常容易受傷的總成，要是使用不當(dāng)或保養(yǎng)不好，很容易損壞甚至出現(xiàn)難以修復(fù)的故障。因此，為了充分發(fā)揮自動(dòng)變速箱的各種優(yōu)勢(shì)，提高其使用效益，并減少自動(dòng)變速箱的故障率，須對(duì)自動(dòng)變速箱進(jìn)行正確的維護(hù)，如要經(jīng)常檢查濟(jì)南變速箱油才行。

The automatic transmission is an assembly with good structure, which is very easy to be injured. If it is used improperly or maintained poorly, it is easy to be damaged or even have faults that are difficult to repair. Therefore, in order to give full play to various advantages of automatic transmission, improve its use efficiency, and reduce the failure rate of automatic transmission, correct maintenance must be carried out for automatic transmission, such as regular inspection of Jinan transmission oil.

自動(dòng)變速箱對(duì)油液的要求嚴(yán)格，它要求油液不僅有潤(rùn)滑、清洗、冷卻作用，還應(yīng)具有傳遞扭矩和傳遞液壓以控制離合器、制動(dòng)器的工作性能，所以自動(dòng)變速箱油是一種特殊的高等級(jí)潤(rùn)滑油，通常稱(chēng)之為ATF。

The automatic transmission has strict requirements on the oil. It requires that the oil not only has the functions of lubrication, cleaning and cooling, but also has the functions of transmitting torque and hydraulic pressure to control the working performance of clutches and brakes. Therefore, the automatic transmission oil is a special high-grade lubricating oil, usually called ATF.

其型號(hào)有很多種，國(guó)內(nèi)常見(jiàn)的有Ford標(biāo)準(zhǔn)F型和GM標(biāo)準(zhǔn)DEXRONII型，使用時(shí)切記要認(rèn)清。ATF型號(hào)不同，其摩擦系數(shù)就不一樣。若該使用DEXRONII型而錯(cuò)用為F型，則會(huì)使自動(dòng)變速箱發(fā)生換擋沖擊和制動(dòng)器、離合器突然嚙合的現(xiàn)象。

There are many types, including Ford standard F type and GM standard DEXRONII type, which are common in China. Please remember to recognize them clearly when using them. Different ATF models have different friction coefficients. If the DEXRONII type is used instead of the F type, the shift impact and sudden engagement of the brake and clutch will occur to the automatic transmission.

F型錯(cuò)用為DEXRONII型則會(huì)引起自動(dòng)變速箱內(nèi)離合器、制動(dòng)器打滑，加速摩擦片早期磨損。

If the F type is wrongly used as DEXRONII type, it will cause the clutch and brake in the automatic transmission to slip and accelerate the early wear of the friction plate.

另外，自動(dòng)變速箱油量的檢查也很重要，自動(dòng)變速箱的生產(chǎn)廠家不同，工作液的檢查條件也就不同。檢查時(shí)一般都要求在變速箱熱態(tài)（油溫50℃80℃）時(shí)將汽車(chē)停放在水平路面上，發(fā)動(dòng)機(jī)怠速運(yùn)轉(zhuǎn)（本田車(chē)規(guī)定發(fā)動(dòng)機(jī)熄火），選擋桿放在P位（日產(chǎn)車(chē)允許放在N位），此時(shí)抽出油尺擦凈后重新插入再拔出檢查，油面應(yīng)達(dá)到油尺上規(guī)定的上限刻度附近為準(zhǔn)。

In addition, the inspection of the automatic transmission oil volume is also very important. The inspection conditions of the working fluid vary with the manufacturer of the automatic transmission. During the inspection, it is generally required to park the car on a level road when the gearbox is hot (oil temperature is 50 ℃ 80 ℃), the engine runs at idle speed (Honda specified that the engine is off), and the gear selector is placed at position P (Nissan allowed to place it at position N). At this time, draw out the dipstick to clean it, insert it again, and then pull it out for inspection. The oil level should reach the upper limit scale specified on the dipstick.

多數(shù)自動(dòng)變速箱要求定期換油，換油周期一般為24萬(wàn)公里。放油前，應(yīng)將變速箱預(yù)熱到工作溫度，以便降低油的粘度，確保油內(nèi)雜質(zhì)和沉淀物隨油一起排出。在預(yù)熱和加油過(guò)程中，汽車(chē)應(yīng)停放在水平地面，并拉緊手制動(dòng)。

Most automatic transmissions require regular oil change, with a general oil change interval of 240000 km. Before draining the oil, the gearbox shall be preheated to the operating temperature to reduce the oil viscosity and ensure that impurities and sediments in the oil are discharged with the oil. During preheating and refueling, the vehicle shall be parked on a level ground and the hand brake shall be tightened.

放完油后，視情況拆下機(jī)油盤(pán)，清洗機(jī)油盤(pán)和過(guò)濾器濾網(wǎng)，然后再將機(jī)油盤(pán)裝好。加油時(shí)，先從加油口注入工作液達(dá)到規(guī)定的標(biāo)準(zhǔn)，起動(dòng)發(fā)動(dòng)機(jī)，在發(fā)動(dòng)機(jī)怠速運(yùn)轉(zhuǎn)的情況下，移動(dòng)選擋桿經(jīng)所有的擋位后回到P位，這樣可使變速箱迅速地?zé)崞?，然后再加油?/div>
