Governor Pressure Solenoid

Governor pressure solenoid generates governor pressure required for transmission upshifts and downshifts. Governor pressure solenoid is located on the valve body. See Fig 1. Inlet side of governor pressure solenoid is exposed to normal transmission line pressure and outlet side provides a passage to the governor circuit in the valve body. Governor pressure solenoid regulates the transmission line pressure to the governor circuit. Electrical supply voltage is supplied to governor pressure solenoid by the PCM. The PCM controls the ground circuit to governor pressure solenoid to provide solenoid operation.
