Select Switch On-Off Solenoid Valve

COMPONENT PARTS

A/T CONTROL SYSTEM : Select Switch On-Off Solenoid Valve

- The select switch ON-OFF solenoid valve is installed to control valve.
- The selector switch ON-OFF solenoid valve controls the switch valve that switches the oil pressure applied to the low & reverse brake and the reverse clutch.
- The selector switch ON-OFF solenoid valve utilizes an ON-OFF solenoid valve.
NOTE:
- The only operations of the valve spool installed inside the coil are pressing or not pressing the ball which seals the hydraulic supply section into the seat. This A/T uses N/L (normal low) type.
- When voltage is not applied to the coil, the force of the pilot pressure presses the ball against the seat, stopping the pilot pressure at that point.
- When voltage is applied to the coil, the valve is pulled in the direction of the coil, disengaging the hydraulic seal which the ball creates. This supplies pilot pressure to the operating locations.
