VF-559N Air Solenoid Valve

  The function of the Transmission solenoid valve 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, functioning in different gears, each controlled by one or several solenoid valves.

  The function of the Solenoid Valve of automatic transmission: The solenoid valve is controlled by the transmission electronic control module TCU. Basically, the pressure in neutral and in gear is a constant value, but the opening of the solenoid valve is adjusted during the shifting process to improve the shifting speed. file smoothness. Different solenoids control different clutches or brakes, working in different gears. Each gear is controlled by one or several solenoid valves.

  Solenoid valve, mainly refers to two pressure regulating solenoid valves, one to adjust the main oil pressure, the other to adjust the hydraulic torque converter lock oil pressure, these two oil pressures also control the oil circuit plate in the shift valve body work, there is a bad work, will cause shift impact, long time will wear out the clutch plate and brake belt in the wave box, causing more serious failure.
