Abstract
A hydrokinetic, multiple ratio torque converter transmission having planetary gear ratio elements that establish a hydrokinetic torque path in low ratio and reverse gear and a bypass torque path in intermediate gear and third gear including a torque converter and an overrunning coupling wherein the intermediate gear and third gear is characterized by a mechanical torque flow or a viscous shear torque flow path, the third gear being a partial hydrokinetic regenerative torque flow path.
