Nissan JF020E valve body

If the valve body of the car's transmission is broken and stuck, it will make it impossible to shift gears and the car cannot be used normally. Damage to the transmission valve body is the most common phenomenon in automatic transmissions. The valve body is a hydraulic control unit. During the operation of the gearbox, the slide valve on the valve body will move left and right, thereby changing the flow direction and pressure of the hydraulic oil, and the car's gearbox can automatically shift gears.

When the valve body of the automobile transmission is broken, it needs to be replaced with a brand new valve body. It is recommended that car owners choose original parts, because original parts are usually more durable and reliable. Only the gearbox of an automatic car has a valve body, while the gearbox of a manual car does not have a valve body.

Remove the oil pan and you can see the filter and valve body. Some cars have damaged valve bodies due to unstable oil pressure regulation. The maintenance of the valve body does not require dismantling the entire gearbox assembly. The valve body can be taken out by removing the oil pan;
