Nissan valve body JF011E single - pressure

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 Transmission 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.

The gearbox valve body is one of the important components in the car's gearbox. Over time, the Transmission Valve Body And Mechatronics will inevitably fail. So how do you tell if the transmission valve body is broken?

2. Car owners not only have an obvious sense of frustration when shifting gears, but also have a strong sense of impact when upshifting. In addition, car owners will feel unsmooth when shifting into gear.

3. Another symptom of a car's gearbox valve body failure is that the oil temperature of the gearbox is high. In this case, the car owner will see the gearbox temperature displayed on the trip computer rising when using the car.

Generally speaking, the cause of gearbox valve body failure may be insufficient sealing, which in turn causes insufficient pressure in the valve body, so the car owner cannot shift gears smoothly. If the car owner does not have the habit of regularly changing the oil in the transmission valve body, the wear of the valve body may be increased, eventually causing it to malfunction and become unable to be used normally.
