How to clean the oil in the gearbox How to clean the oil in the gearbox?

1, automatic gearbox is a kind of equipment that can automatically shift gears according to engine speed, which is relative to manual gearbox. The car with automatic transmission can automatically change the speed and torque according to the road conditions, and the driver can concentrate on the road traffic without being flustered by shifting gears. Under normal circumstances, the lubricating oil of the automatic transmission is changed every two years, and the automatic transmission is cleaned and maintained every 40,000 kilometers.

2. 49% of the lubricating oil in the automatic transmission cannot be discharged from the automatic transmission by atmospheric pressure, and the residual oil will gather with the sludge and impurities in the valve body, torque converter and cooling pipeline. If it is not cleaned, it will cause the internal oil circuit of the system to be blocked. More than 99% of automatic transmission failures are caused by overheating and impurities in automatic transmission lubricating oil.

3. Traditional maintenance methods often can't completely replace the transmission fluid: remove the oil bottom screw of the automatic transmission and drain the oil for oil change, but only 30% of the oil can be replaced at most, and nearly 70% of the dirty oil remains in the system. Many cars that use automatic gearboxes will be disintegrated and overhauled in about 200,000 kilometers.
