Abstract
A multi-speed transmission for transmitting power from a power source includes a torque converter as well as dual clutches which may be arranged as dual input clutches or dual output clutches. To combine the smoothness and ratio boosting effects of a torque converter with the low spin loses associated with synchronizers used in dual clutch designs. The torque converter and dual clutches as well as synchronizers and a plurality of intermeshing gears are utilized to transfer torque from an input member to an output member at a plurality of speed ratios.
