自動變速箱打滑是自動變速箱的常見故障之一。而自動變速箱漏油是造成自動變速箱打滑的最前期原因。液壓控制系統的各連接部位上都有油封和密封墊，這些部件是常發生漏油的地方。液壓系統漏油會引起油路壓力下降，而油位下降則會引起自動變速箱打滑。自動變速箱打滑故障，總的來說，都可以通過自動變速箱油位與品質來分辨。如自動變速箱油位過低，但無雜質，則查找漏油處進行修復故障基本可排除；如自動變速箱油位過高，無雜質，調整自動變速箱油位，故障基本可排除；如自動變速箱油呈棕黑色或有燒焦味，則應拆解變速箱，排查是否內部零件（摩擦片、制動帶等）存在磨損。

Automatic transmission slippage is one of the common faults in automatic transmissions. And automatic transmission oil leakage is the earliest cause of automatic transmission slippage. The various connection parts of the hydraulic control system are equipped with oil seals and gaskets, which are common sources of oil leakage. Hydraulic system oil leakage can cause a decrease in oil circuit pressure, while a decrease in oil level can cause automatic transmission slippage. Automatic transmission slip faults can be identified by the oil level and quality of the automatic transmission. If the oil level of the automatic transmission is too low but there are no impurities, the fault can be basically eliminated by searching for the oil leakage and repairing it; If the automatic transmission oil level is too high and there are no impurities, adjusting the automatic transmission oil level can basically eliminate the fault; If the automatic transmission oil is brownish black or has a burnt smell, the transmission should be disassembled and checked for internal parts (friction plates, brake bands, etc.) that are worn.

1、液壓油油面太低；液壓油油面太高，運轉中被行星排劇烈攪動后產生大量氣泡；

1. The hydraulic oil level is too low; The hydraulic oil level is too high, causing a large number of bubbles to be generated during operation due to violent agitation by the planetary gear;

2、離合器或制動器摩擦片、制動帶磨損過甚或燒焦；油泵磨損過甚或主油路泄漏，造成油路油壓過低；

2. Excessive wear or burning of clutch or brake friction plates and brake bands; Excessive wear of the oil pump or even leakage of the main oil circuit, resulting in low oil pressure in the oil circuit;

3、單向超越離合器打滑；離合器或制動器活塞密封圈損壞，導致漏油；減振器活塞密封圈損壞，導致漏油。

3. One way overrunning clutch slipping; Damaged clutch or brake piston sealing ring, resulting in oil leakage; The sealing ring of the shock absorber piston is damaged, resulting in oil leakage.
