An infinitely variable forward speed mechanical transmission uses asymmetric helical/spur gear trains mounted to rotate within a rotor assembly to reduce the torque output within the rotor assembly through inefficiency of the asymmetric gear trains. The rotor assembly includes integrated input and output hubs having adjacent radially flush outer control surfaces, with the output hub in mesh with the asymmetric helical/spur gear trains in mesh with an output shaft. A transmission speed control device connected to a control gear connected to a control tang of a wrap spring positioned about the control surfaces of the input and output hubs provides infinitely variable control of the relative rotation of the two hubs to selectively control the torque output of the transmission. A planetary gear set in constant mesh with the transmission input through the input hub provides a full-time low-gear ratio, and an attached dual sprague clutch assembly determines the driving output train of the transmission between the planetary gear set and the output shaft.
