As vehicle speed and governor pressure increase, the force of the governor oil acting on the converter clutch shift valve overcomes the pressure of Modulated Throttle Valve (M.T.V.) up oil and the force of the converter clutch Throttle Valve (T.V.) spring. This allows the converter clutch shift valve to open and 2nd oil to enter the converter clutch signal passage. Converter signal oil will exhaust at the T.C.C. solenoid until a signal is received from the vehicles external controls.
