自動變速器換油注意事項

Automatic transmission oil change precautions

經(jīng)常檢查自動變速器油溫，正常情況下，自動變速器油溫應在70~80°C之間，也就是說，在正常行駛中途停車休息的時候，用手摸自動變速器外殼，感到有點燙手，但手能在變速器外殼上放不到一秒左右的時間。這樣的溫度基本就是正常的，這也是參考溫度，如果車輛長時間低速行駛，油溫會升高。

Check the oil temperature of the automatic transmission frequently. Under normal circumstances, the oil temperature of the automatic transmission should be between 70~80 ° C, that is to say, when stopping and resting during normal driving, touching the automatic transmission housing with your hand feels a little hot, but your hand can not be placed on the transmission housing for about one second. This temperature is basically normal, which is also the reference temperature. If the vehicle runs at low speed for a long time, the oil temperature will rise.

如果油溫升高，就要檢查自動變速器油液面的高度，往往是液面高度降低后才會導致油溫升高。自動變速器油液面高度檢查時分為兩種情況，一種是冷態(tài)檢查，就是車輛在停駛狀態(tài)下，油液的高度應該在油尺的上刻度線位置。另一種是熱態(tài)檢查，就是在車輛行駛后，自動變速器溫度達到正常值的時候，抽出油尺，油液高度應在油尺下刻度線。如果太低就要添加。

If the oil temperature rises, it is necessary to check the automatic transmission oil level. Usually, the oil temperature rises only after the level decreases. The automatic transmission oil level is checked in two ways. One is the cold check, which means that the oil level should be at the upper scale of the dipstick when the vehicle is stopped. The other is the hot state inspection, that is, when the automatic transmission temperature reaches the normal value after the vehicle is driven, pull out the dipstick, and the oil level should be at the scale line under the dipstick. Add if it is too low.

濟南自動變速箱維修廠家建議大家在檢查油液面高度時，同時要觀察自動變速器油液的品質(zhì)，正常的自動變速器油液應該是清澈帶紅色。如果是深褐色、黑色、或者有焦臭味（滴一滴在手指上用鼻子嗅一下），說明自動變速器曾經(jīng)過熱或長時間沒有換油。

Jinan automatic transmission maintenance manufacturer suggests that when checking the oil level, you should also observe the quality of the automatic transmission oil. The normal automatic transmission oil should be clear and red. If it is dark brown, black, or has a burning smell (sniff it with your nose every drop on your finger), it indicates that the automatic transmission has been overheated or has not changed the oil for a long time.

如果其中有黑色顆粒狀物質(zhì)，標明自動變速器內(nèi)部的離合器片、制動片等燒蝕，應拆開自動變速器進行檢查，并徹底清洗其零部件。如果其中有銀白色的金屬顆粒，或者碎鐵屑標明自動變速器內(nèi)部的閥體、軸承或行星齒輪磨損嚴重，也必須拆解自動變速器。如果油尺上帶有難以擦凈的膠狀物，說明自動變速器油（ATF）因過熱氧化，應更換自動變速器油和清洗濾網(wǎng)。

If there is black granular substance in it, it indicates that the clutch disc, brake disc, etc. inside the automatic transmission are ablated. The automatic transmission shall be disassembled for inspection, and its parts and components shall be thoroughly cleaned. If there are silver white metal particles or scrap iron indicating that the valve body, bearing or planetary gear inside the automatic transmission is seriously worn, the automatic transmission must also be disassembled. If the dipstick has a colloid that is difficult to clean, it indicates that the automatic transmission oil (ATF) is oxidized due to overheating. Replace the ATF and clean the filter screen.

自動變速器換油使用誤區(qū)

Incorrect use of automatic transmission oil change

誤區(qū)一：變質(zhì)才換

Myth 1: change after deterioration

自動變速器油的更換周期是以行駛公里數(shù)或使用時間為準，如果車輛使用手冊未標明，則按照6萬-8萬公里的里程來更換。

The replacement cycle of automatic transmission oil is based on the mileage or service time. If it is not indicated in the vehicle manual, it shall be replaced according to the mileage of 60000-80000 km.

誤區(qū)二：兩種換油方式

Myth 2: two oil change methods

“手換”操作方便，耗時少，缺點是換油不徹底，只能放掉四分之一至三分之一舊油液，大約是4升。“機換”整個過程約需1小時，需油12升左右。這種換油方式的優(yōu)點是換油比較徹底，能夠放掉85%以上的舊油液。

The "manual change" is easy to operate and takes less time. The disadvantage is that the oil change is not complete. Only a quarter to a third of the old oil can be drained, about 4 liters. The whole process of "machine replacement" takes about 1 hour and requires about 12 liters of oil. The advantage of this oil change method is that the oil change is relatively complete, and more than 85% of the old oil can be discharged.

值得注意的是，兩種換油方法都要在發(fā)動機啟動的情況下進行。更換自動變速器油液，在操作的時候必須是在熱車的狀態(tài)下，更換前應行駛20分鐘以上，不能冷車換油。換油時要啟動發(fā)動機，把各擋位從P擋到N、D、L1、L2等擋位來回撥動，然后才開始換油液。

It is worth noting that both oil change methods should be carried out when the engine is started. When changing the automatic transmission fluid, the operation must be in the hot vehicle state. The vehicle shall be driven for more than 20 minutes before replacement, and the cold vehicle is not allowed to change the oil. When changing the oil, start the engine, shift the gears from P to N, D, L1 and L2, and then start to change the oil.

誤區(qū)三：無需換油

Myth 3: no need to change oil

濟南自動變速箱維修廠家發(fā)現(xiàn)很多車主，并沒有養(yǎng)成更換自動變速器油的意識。而更換了劣質(zhì)油和不按型號換油，也會導致自動變速器“短命”。自動變速箱油經(jīng)常以被忽視的形象存在，等發(fā)現(xiàn)的時候才知道原來成本很高，所以注意自動變速箱的維護和保養(yǎng)尤為重要。

Jinan automatic transmission maintenance manufacturers found that many car owners did not develop the awareness of changing automatic transmission oil. The replacement of inferior oil or not according to the model will also lead to "short life" of the automatic transmission. Automatic transmission oil often exists in the image of being ignored. When it is discovered, it is known that the original cost is very high. Therefore, it is particularly important to pay attention to the maintenance of automatic transmission.
