液壓機自動控制系統的連接部位常有骨架密封和密封墊，這些部位常處于漏油區域。液壓傳動系統的漏油會降低油路的工作壓力，油量的減少會導致自動變速箱打滑。對重慶自動變速箱維修易產生漏油的部位應逐一檢查。
The connection parts of the automatic control system of hydraulic press often have skeleton seals and gaskets, which are often in the oil leakage area. The oil leakage of the hydraulic transmission system will reduce the working pressure of the oil circuit, and the reduction of the oil volume will cause the automatic transmission to slip. The parts prone to oil leakage during maintenance of Chongqing automatic transmission shall be inspected one by one.
綜上所述，自動變速箱打滑的原因有七個。
To sum up, there are seven reasons for automatic transmission slip.
1、自動變速箱油位過低
1. The automatic transmission oil level is too low
2、自動變速箱油位過高，工作時被行星排強烈攪拌后產生大量氣泡
2. The oil level of automatic transmission is too high, and a large number of bubbles are generated after being strongly stirred by planetary exhaust during operation
3、離合器或制動系統摩擦片和制動系統皮帶損壞或燒壞
3. The clutch or brake system friction plate and brake system belt are damaged or burned
4、汽油泵損壞甚至主油路泄漏，導致油路蒸汽壓力低
4. The gasoline pump is damaged and even the main oil circuit leaks, resulting in low steam pressure in the oil circuit
5、單向超越離合器打滑
5. One way overrunning clutch slipping
6、離合器或制動系統活塞桿密封圈損壞，漏油
6. The piston rod sealing ring of clutch or braking system is damaged and leaks oil
7、減震器活塞桿密封圈損壞，漏油
7. The sealing ring of shock absorber piston rod is damaged and leaks oil
