Shift Solenoid: Description and Operation
3-2 Control Solenoid
3-2 Control Solenoid Circuit
Purpose:
The 3-2 control solenoid is a pulse width modulated solenoid used to improve the 3-2 downshift. The solenoid regulates the release of the 3-4
clutch and 2-4 band apply.
Operation:
The solenoid uses duty cycle to regulate pressures that smoothly release the clutch and apply the band. Duty cycle is normally about 0% in first
gear, and 90% in all other drive gears. Duty cycle drops during 3-2 downshift.
Throttle position, Vehicle speed and the commanded gear are used to determine duty cycle.
Location:
The 3-2 control solenoid is attached to the valve body inside the transmission.
