(1)自动变速箱维修故障现象
(1) Troubleshooting of automatic transmission
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 signs, but after the automatic transmission maintenance personnel came, they stepped on the accelerator pedal twice, and the car was able to drive again, and then drove normally,
但放了一夜后轿车又无法行驶。
But after one night, the car couldn't run.

(2) Automatic Transmission Maintenance Fault Analysis
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 maintenance of automatic transmission must change the oil regularly according to the specified mileage: the whole transmission system must be thoroughly cleaned after the clutch or brake is ablated. If the transmission oil is seriously oxidized or dirty, the control valve should be closed
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 slide valve in the valve is easy to be stuck. The main pressure regulating valve is stuck on the oil drain side. Without the main oil pressure, the transmission will not be in gear, and the car will stop suddenly when it is running without any signs
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 operation, and the car can run normally. Since the transmission has not been 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。
The seriously oxidized oil and impurities still exist. After one night's discharge, the main pressure regulating valve may be stuck on the oil drain side again, and the car can't drive.

(3) Automatic transmission maintenance troubleshooting
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 thoroughly clean the whole transmission system, and the fault can be removed after the oil is changed again.
