Abstract
A nonsynchronous, automatic transmission with overdrive which includes a torque converter coupled to an input member, a planetary gear set comprising a forward sun gear, a reverse sun gear and an output member, clutches for selectively coupling the torque converter to the output member through each of a plurality of torque paths, an overdrive brake coupled to the reverse sun gear, a direct clutch for selecting a torque path connection between the input member and the output member, and a one-way clutch coupled to the direct clutch and the forward sun gear. In the preferred embodiment, the planetray gear set is a compound planetary gear set, although separate planetary sets may be combined as desired. The invention can be employed with a variety of torque path configurations. Preferably, the direct clutch and the one-way clutch are coupled in the same clutch housing and actuated by a single piston.
