(1)自动变速箱维修故障现象
(1) Automatic transmission maintenance fault phenomenon
一辆轿车行驶中没有任何征兆的情况下突然停驶，但自动变速箱维修人员来后，踩了两次加速踏板，轿车又能行驶了，而且随后行驶正常，
A car suddenly stopped driving without any sign, but after the automatic transmission maintenance personnel came and stepped on the accelerator pedal twice, the car could run again, and then it ran normally,
但放了一夜后轿车又无法行驶。
But after a night's release, the car couldn't drive.

(2) Fault analysis of automatic transmission maintenance
自动变速箱维修必须按规定里程定期换油：离合器或制动器发生烧蚀后必须彻底清洗整个变速器系统。如变速箱油严重氧化或过脏，控制阀
The oil must be changed regularly according to the specified mileage for automatic transmission maintenance: after the clutch or brake is ablated, the whole transmission system must be thoroughly cleaned. If the transmission oil is severely oxidized or dirty, the control valve
内的滑阀就容易发生卡滞。而主调压阀卡滞在泄油—侧，没有主油压，变速箱就没有挡，汽车在行驶中没有任何征兆的情况下，就会突然停
The spool valve in the is easy to get stuck. The main pressure regulating valve is stuck on the oil drain side. Without the main oil pressure, the gearbox will not be in gear. When the car is running without any signs, it will suddenly stop
驶。急加速后，在油液冲击下，导致主调压阀卡滞的杂质被冲走，主调压阀工作暂时恢复正常，汽车可正常行驶。由于并没有清洗变速器，
Drive. After rapid acceleration, under the impact of oil, the impurities that cause the main pressure regulating valve to be stuck are washed away, the main pressure regulating valve temporarily returns to normal, and the car can run normally. Because the transmission was not cleaned,
严重氧化的油和杂质依然存在，放了一夜后，主调压阀有可能再次卡滞在泄油一侧，轿车又无法行驶。
Severely oxidized oil and impurities still exist. After being discharged overnight, the main pressure regulating valve may be stuck on the oil drain side again, and the car can't drive.

自动变速箱维修人员彻底清洗整个变速器系统，重新换油后，故障即可捧除。
The automatic transmission maintenance personnel shall thoroughly clean the whole transmission system, and the fault can be removed after changing the oil again.
