Now more and more car owners choose to use automatic transmission, because automatic transmission is lighter and easier. Coupled with the increasingly congested traffic, people prefer to use automatic transmission. But many car owners after buying a car, in the new car stage to care for the car. Once you get into the "boredom" period, you can start to drive, and you don't care. If you have problems, you need to fix them.

而往往汽車發(fā)生意外再維修時，因為沒有及時維修保養(yǎng)，以致自動變速器的小故障擴大、惡化而導(dǎo)致大事故。因此在日常用車的過程中車主門一定要及時地養(yǎng)護自動變速箱，以免自動變速箱出現(xiàn)故障為行車帶來不便。

And often when the car accident repair, because there is no timely maintenance, so that the automatic transmission of small fault expansion, deterioration and lead to major accidents. Therefore, in the process of daily use of the car, the main door must be timely maintenance of the automatic transmission, in order to avoid the automatic transmission failure to bring inconvenience to the driving.

自動變速箱工作過程（液力傳動-變扭器、離合器等），由于變扭器在傳遞發(fā)動機時有一部分時間是利用液力實現(xiàn)的，因此這樣會形成大量的熱能；同時離合器和制動器在工作時產(chǎn)生摩擦力矩時也會產(chǎn)生大的熱，因此會導(dǎo)致ATF在一定時間內(nèi)變質(zhì)。

During the working process of automatic transmission (hydraulic transmission - torque converter, clutch, etc.), the torque converter uses hydraulic power to transfer the engine part of the time, so a lot of heat energy will be generated; at the same time, when the clutch and brake generate friction torque, they will also generate large heat, so the ATF will deteriorate in a certain period of time.

自動變速箱工作環(huán)境（溫度、環(huán)境等），經(jīng)常性工作較苛刻環(huán)境下，由于變速箱的工作載荷較大導(dǎo)致變速箱的工作溫度升高，長時間會導(dǎo)致ATF提前變質(zhì)。

The working environment of automatic transmission (temperature, environment, etc.) is often harsh. Due to the large working load of the transmission, the working temperature of the transmission rises, and the ATF deteriorates in advance for a long time.

自動變速箱使用條件，駕駛員總追求動感駕駛模式，變速箱總是在發(fā)動機高速轉(zhuǎn)速完成換檔，長時間達(dá)不到高檔位的傳動比，所以變速箱溫度會持續(xù)升高從而導(dǎo)致ATF變質(zhì)。

The use condition of automatic transmission is that drivers always pursue the dynamic driving mode. The transmission always shifts at the high speed of the engine, which can not reach the high gear transmission ratio for a long time. Therefore, the temperature of the transmission will continue to rise, resulting in the deterioration of ATF.

自動變速數(shù)據(jù)參數(shù)的變化（壓力、摩擦系數(shù)等），在某些工況下由于自動變速箱的一些正常參數(shù)下降，導(dǎo)致壓力、摩擦系數(shù)的降低而影響變速箱的正常運轉(zhuǎn)。

The change of data parameters (pressure, friction coefficient, etc.) of automatic transmission affects the normal operation of transmission due to the decrease of some normal parameters of automatic transmission under some working conditions.
