for Nissan Valve Body Parts CVT JF015E RE0F11A Transmission Solenoid Valve Kit

    The role of the solenoid valve in the gearbox is to adjust the opening of the solenoid valve during the shift process to improve the smoothness of the shift. Different solenoid valves control different clutches or brakes, and play a role in different gear, each gear is controlled by one or several solenoid valves

In hydraulic system, solenoid valve is divided into pilot control and direct drive control. Pilot solenoid valve control pressure and flow rate is relatively low, can not directly drive the actuator, can only provide pilot control pressure.

  Introduction to the role of automatic transmission solenoid valve:

1. The solenoid valve is controlled by the transmission electronic control module TCU, basically the pressure in neutral and in gear is a constant value.

2. Adjust the opening of the solenoid valve during the shift process to improve the smoothness of the shift.

3. Different solenoid valves control different clutches or brakes and play a role in different gears.

4. Each gear is controlled by one or several solenoid valves.

     Switch type: Through a certain current or voltage, the internal coil of the battery valve is energized, and then the internal needle valve or ball valve is driven to shift, thereby blocking the section or opening the oil circuit. More used to control shift

    Pulse type: current duty cycle control, through frequency control. Used to adjust oil pressure.
