現在越來越多的車主選擇使自動擋汽車，因為自動擋比較輕便、省事.加上越來越擁堵的交通情況，人們更加喜歡使用自動擋了。但很多車主買了車之后，在新車階段對愛車呵護有加。一旦進入“厭倦期”就開始能開就不管，有問題去修。
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.
而往往汽車發生意外再維修時，因為沒有及時維修保養，以致自動變速器的小故障擴大、惡化而導致大事故。因此在日常用車的過程中車主門一定要及時地養護自動變速箱，以免自動變速箱出現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動機時有一部分時間是利用液力實現的，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生摩擦力矩時也會產生大的熱，因此會導致ATF在一定時間內變質。
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.
自動變速箱工作環境（溫度、環境等），經常性工作較苛刻環境下，由于變速箱的工作載荷較大導致變速箱的工作溫度升高，長時間會導致ATF提前變質。
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，變速箱總是在發動機高速轉速完成換檔，長時間達不到高檔位的傳動比，所以變速箱溫度會持續升高從而導致ATF變質。
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.
自動變速數據參數的變化（壓力、摩擦系數等），在某些工況下由于自動變速箱的一些正常參數下降，導致壓力、摩擦系數的降低而影響變速箱的正常運轉。
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.
