The gearbox valve body is a hydraulic control module. When the gearbox is working, the rotary vane pump on the oil circuit board moves up and down to change the gear oil inflow and pressure. In this way, the gearbox can be automatically shifted. If the oil circuit board of the transmission is damaged, the oil circuit board becomes stuck or leaks, which will cause shifting shock. It is worth mentioning that the rotary vane pump on the oil circuit board is automatically switched on and off by the motor control module. of. It is impossible to drive the car again after the transmission valve body and mechatronics are broken. If the transmission valve body is broken, it will become stuck. If leakage occurs, it will cause the transmission to have shifting shock during the shifting process, which will easily reduce the efficiency of the shifting. At the same time, it will also It will cause the driving force of the vehicle to be reduced. The transmission valve body is on top of…
