C-3168 A CONTROL VALVE MECHANISM FOR A POWER TRANSMISSION Abstract of the Disclosure; An electro-hydraulic control for a power transmission has a solenoid controlled shift valve and a hydraulic controlled shift valve. Preferably, the solenoid controlled valve controls the control clutch while the hydraulic controlled valve controls the clutch or brake which is effective to establish a drive ratio in the transmission. When a ratio change involving the disengagement of the clutch or brake occurs, the exhaust fluid therefrom operates on an electrical switch which is effective to provide momentary disengagement of the torque converter clutch.
