My car is 2014 automatic elite model, I believe that most car owners who choose to buy automatic gear are because automatic gear does not need to change frequently, only need to control the throttle brake convenience, now more and more automatic transmission cars, so whether the automatic transmission oil needs to be changed is also a matter of concern, although our manual says that the gearbox is maintenance-free. But I feel that the gearbox is always in a state of transmission, friction, and high temperature, which is bound to produce oily mud and other bastards like iron shavings. So after asking a few auto mechanic friends, I decided to change the gearbox oil for my car.
Automatic transmission oil is referred to as ATF (Automatic Transmission Fluid), which is specially used for automatic transmission. The main function of gearbox oil is lubrication, reducing friction, controlling temperature and so on.
In the current gearbox oil, try to choose the original factory ATF. Do not misuse automatic transmission oil. The car maintenance manual uses the same model as the ATF. The friction coefficient of ATF is different due to different models. Some automobile manufacturers design targeted oil products according to the technical specifications of the automobile transmission, which can maintain the good mechanical properties of the transmission and prolong its life.
There are two main ways to change gearbox oil, namely gravity oil change, oil sump removal, and circulation machine exchange. The first two ways of changing oil are not very thorough, so I choose the last one. I won’t say any more about the reason.
In order to prevent the suspicion of advertising, some of the pictures were mosaic.
In the distance is my car, quietly waiting for me to open, 5 years of hard work, there has never been any problem
Changan CS75 sales are very good, can be seen everywhere, I believe the quality is really good
The configuration of the car is rich, complete with Aixin 6-speed hand-integrated gearbox, electronic handbrake, automatic parking and so on.
The car is equipped with on-board navigation, out-going artifact and accurate positioning.
The front and rear are equipped with six radars to effectively prevent rubbing.
The car is equipped with a reversing image, which can be easily operated by beginners.
The car has a wide field of vision and knows everything like the back of his hand.
Arrived at the repair shop, ready to change the gearbox oil, affectionately spread the seat cushion for the car.

Release some of the oil first, so that the oil can be changed more quickly.
The machine has been connected
The switch uses a 12V power supply, so the battery is needed.
Need to start the car and check the joint for oil leakage
Clean first
The car battery is very powerful. It has been on fire for 5 years.

Need to hang into each gear for cleaning.
Cleaning is completed and the same amount of exchange is carried out.
The car needs to start all the time.

Remove the oil pipeline
In order to prevent oil leakage, two pipe hoops were specially smashed, and a test drive was carried out outside, and the service was good.
After changing the gearbox oil, the car feels smoother than before, and the throttle response is more sensitive. Thank you
