Automatic transmission car is easy to use and convenient, especially suitable for driving in urban traffic, which brings great convenience to car owners. However, the automatic transmission system is a very precise assembly, especially the manual automatic transmission, whose structure is more complex. Therefore, once the automatic transmission fails, the maintenance is very troublesome and expensive. Therefore, the automatic transmission needs more careful care and maintenance. Among them, the important thing should be the maintenance and replacement of transmission oil. As an automatic transmission oil, the impact during gear shifting is great. Although our car owners can't feel it, the wear is much higher than that of ordinary manual cars. Therefore, it is very important to choose a suitable lubricating oil and replace the lubricating oil regularly.

1、保養(yǎng)變速箱換油是關(guān)鍵。如果近來發(fā)現(xiàn)您的自動(dòng)擋車換擋時(shí)震動(dòng)比較大，換擋速度比較遲緩，那說明該給變速箱換機(jī)油了。自動(dòng)排擋車不比手動(dòng)排擋車，手動(dòng)變速箱構(gòu)造比較簡(jiǎn)單，即使該換機(jī)油了多撐一些日子也無(wú)妨，但自動(dòng)排擋車的換油可省不得，2萬(wàn)公里該換就得換，否則時(shí)間一長(zhǎng)，車子就容易出問題，這是因?yàn)樽詣?dòng)擋車在使用過程中不斷自動(dòng)換齒輪，齒輪難免出現(xiàn)磨損。自動(dòng)排擋潤(rùn)滑油劑會(huì)在變速箱的各部件外層“包”上一層保護(hù)膜，排擋移動(dòng)時(shí)就會(huì)更順暢。一般不管是手動(dòng)變速箱還是自動(dòng)變速箱建議12個(gè)月或2萬(wàn)公里更換一次自動(dòng)變速箱油。

1. Maintaining the transmission and changing the oil is the key. If it is found recently that your automatic block has a large vibration when shifting and the shift speed is slow, it indicates that it is time to change the oil of the transmission. The automatic transmission is not as simple as the manual transmission. Even if the oil should be changed for a few more days, it doesn't hurt. However, the oil change of the automatic transmission can't be saved. You have to change it when you need to change it for 20000 kilometers. Otherwise, the car is prone to problems over time. This is because the gear of the automatic transmission is inevitably worn due to the continuous automatic gear change during the use of the automatic transmission. The automatic gear lubricant will "wrap" a layer of protective film on the outer layer of all parts of the gearbox, which will make the gear move more smoothly. Generally, whether it is manual transmission or automatic transmission, it is recommended to replace the automatic transmission oil once every 12 months or 20000 kilometers.

2、定期檢查變速箱油。自動(dòng)變速箱內(nèi)注入的是一種叫ATF的潤(rùn)滑油，它的作用除了潤(rùn)滑降溫，更主要的是要傳遞發(fā)動(dòng)機(jī)和變速箱之間的動(dòng)力。ATF機(jī)油的工作溫度一般在120攝氏度左右，因此對(duì)機(jī)油的質(zhì)量要求很高，還需要保持清潔。

2. Check the transmission oil regularly. A lubricating oil called ATF is injected into the automatic transmission. Its function is not only to lubricate and cool down, but also to transfer the power between the engine and the transmission. The working temperature of ATF engine oil is generally about 120 ℃, so the quality of engine oil is very high and it needs to be kept clean.

3、要經(jīng)常檢查自動(dòng)變速箱油液位是否正常。自動(dòng)變速箱油的檢查方法與發(fā)動(dòng)機(jī)油不一樣，發(fā)動(dòng)機(jī)機(jī)油在冷卻狀態(tài)下檢查、而變速箱油是需要將油預(yù)熱到50℃左右，再將擋位桿在各擋位停留2秒鐘后置于停車擋，此時(shí)油尺正常油面應(yīng)位于高與低線之間，如不夠，應(yīng)及時(shí)添加相同品質(zhì)的潤(rùn)滑油品。

3. Always check whether the automatic transmission oil level is normal. The inspection method of automatic transmission oil is different from that of engine oil. The engine oil is inspected when it is cold, and the transmission oil needs to be preheated to about 50 ℃, and then the gear lever is placed in the parking gear after staying in each gear for 2 seconds. At this time, the normal oil level of the dipstick should be between the high and low lines. If it is not enough, the lubricating oil of the same quality should be added in time.

4、正確更換變速箱油。一般在更換自動(dòng)變速箱油時(shí)大都是卸下自動(dòng)變速箱油底的螺絲來漏掉舊機(jī)油再加入新機(jī)油，但這樣大約只能換上30%的新油，而還有70%的舊油仍殘留在變速箱內(nèi)。如果以拆卸油底殼的方式進(jìn)行換潤(rùn)滑油，則可達(dá)到70%的換油率，這樣其實(shí)就已經(jīng)能確保變速箱的健康了。但目前較好的換潤(rùn)滑油方法是動(dòng)態(tài)換油，采用專用的變速箱清洗設(shè)備，在變速箱運(yùn)轉(zhuǎn)的過程中，將舊油充分循環(huán)、排放干凈后再加入新的變速箱油，從而使換油率高達(dá)90%以上。

4. Replace the transmission oil correctly. Generally, when changing the automatic transmission oil, most of them remove the screws at the oil bottom of the automatic transmission to leak the old oil and then add new oil, but in this way, only about 30% of the new oil can be replaced, and 70% of the old oil is still left in the transmission. If the lubricating oil is changed by removing the oil pan, the oil change rate of 70% can be achieved, which can actually ensure the health of the transmission. However, at present, the better method of changing lubricating oil is dynamic oil change. Special gearbox cleaning equipment is adopted. In the process of gearbox operation, the old oil is fully circulated and drained, and then new gearbox oil is added, so that the oil change rate is up to more than 90%.
