自動變速箱與發動機、底盤懸掛總稱為汽車三大件，其中變速箱結構復雜，因此維修成本很高，一旦變速箱出現故障需要維修，費用可能比修發動機還要貴，因此做好日常的保養尤為重要，而變速箱保養的關鍵，是變速箱油。而不同的變速箱需要適配專用的變速箱油，下面濟南自動變速箱維修人員為您分析：

The automatic transmission, engine and chassis suspension are collectively referred to as the three major parts of automobile. The transmission structure is complex, so the maintenance cost is very high. Once the transmission fails, the maintenance cost may be more expensive than that of the engine. Therefore, it is particularly important to do a good job in daily maintenance. The key to the maintenance of the transmission is the transmission oil. Different gearboxes need to be equipped with special transmission oil. The following is the analysis of Jinan automatic transmission maintenance personnel:

手動變速箱（MT）

Manual transmission (MT)

俗稱“手動檔”，用手撥動變速桿來改變變速器內的齒輪嚙合位置和傳動比，從而實現變速，需要配合踩離合器。選用合成型高黏度指數優良基礎油和高級多功能添加劑調配而成。可以在崎嶇山路頻繁換擋等苛刻工況下正常工作，對機器零部件起到很好的保護作用。

Commonly known as "manual gear", shift the gear lever by hand to change the gear meshing position and transmission ratio in the transmission, so as to achieve speed change. It is necessary to step on the clutch. It is blended with synthetic base oil with high viscosity index and advanced multifunctional additives. It can work normally under harsh conditions such as frequent gear shifting on rugged mountain roads, and play a good role in protecting machine parts.

自動變速箱（AT）

Automatic transmission (AT)

根據油門踏板程度以及車速的變化，同時發動機負荷和汽車的運行工況，自動換入不同擋位工作。自動變速箱油黏度相對較低，好選擇抗氧化性和流動性較好的油液，從而提高傳動效率。

According to the degree of the accelerator pedal and the change of the vehicle speed, the engine load and the operating conditions of the vehicle will automatically shift into different gears to work. The viscosity of the automatic transmission oil is relatively low, so it is better to select the oil with good oxidation resistance and fluidity to improve the transmission efficiency.

無級變速箱（CVT）

CVT

沒有明確擋位之分，省去了復雜的齒輪組合變速傳動，只用了兩組帶輪進行變速傳動。因此，為了防止無級變速箱特殊的傳動鏈條打滑，選擇的變速箱油需要具有一定的阻尼摩擦力。優異的燃油經濟性，有效延長換油周期，降低運行成本；優異的摩擦特性與優異的流變性能，讓您擁有很佳的駕乘舒適感。

There is no clear gear division, and the complex gear combination variable transmission is omitted, and only two sets of pulley are used for variable transmission. Therefore, in order to prevent the special transmission chain of the CVT from slipping, the selected transmission oil needs to have certain damping friction. Excellent fuel economy, effectively extending the oil change period and reducing the operating cost; Excellent friction characteristics and excellent rheological properties make you have a good driving comfort.

雙離合變速箱（DCT）

Dual clutch transmission (DCT)

顧名思義，有兩組離合器。離合器位于發動機與變速器之間，是既能傳遞動力又能切斷動力的傳動機構。雙離合變速箱結合了手動變速箱和自動變速箱的優點，沒有變矩器，而是通過兩套離合器的相互交替工作，來實現無間隙換擋。變速箱油，專為濕式雙離合變速器開發，使用優良合成型基礎油及進口添加劑調和而成，全面滿足雙離合變速器的潤滑需求，全面保護愛車。

As the name implies, there are two sets of clutches. The clutch is located between the engine and the transmission. It is a transmission mechanism that can transmit power and cut off power. The dual-clutch transmission combines the advantages of the manual transmission and the automatic transmission. There is no torque converter. Instead, the two sets of clutches work alternately to achieve gearshift without backlash. Transmission oil, specially developed for wet dual-clutch transmission, is blended with excellent synthetic base oil and imported additives to fully meet the lubrication requirements of dual-clutch transmission and fully protect your car.

在用車時，要特別注意油液高度，既不能過多，也不能過少。油面過低，容易導致自動變速箱燒毀，而油面過高，則可能導致自動變速箱內部溫度過高，出現異響等故障。更多相關內容就來我們網站http://m.ihudie.cn咨詢了解吧！

When using the vehicle, pay special attention to the oil level, neither too much nor too little. If the oil level is too low, it is easy to cause the automatic transmission to burn out, while if the oil level is too high, it may cause the internal temperature of the automatic transmission to be too high, abnormal noise and other faults.
