6F24 Power Flow
Hydraulic power flow is controlled by the TCM and the solenoids attached to the valve body. The TCM toggles control voltage or ground on and off in a duty cycle to regulate the line pressure flowing through the valve body. The lower the duty cycle percentage is the higher the line pressure. The pressure can be measured with (special tool #10424, Adapter, Transmission Pressure) and (special tool #C-3293-SP, Gauge, Pressure 0-300 P.S.I.).
