ABSTRACT:
A multiple-shaft transmission having multiple gear ratios, at least one ro having a gearset with gear elements (58, 144, 204) that are journalled on their respective shafts (44, 112, 206) and that are continuously in mesh, each shaft carrying a clutch assembly (178, 188) that may be selectively engaged and disengaged to complete and to interrupt a torque flow path through the gearset whereby the gear elements are isolated from the input and output driven and do not contribute to the total inertia mass of the driven rotating components of the transmission when they do not form a part of the torque flow path, thus reducing gear rattle and reducing shift efforts required to effect gear ratio changes.
