ABSTRACT:
A multiple-speed ratio transmission mechanism for an automotive vehicle includes a torque input shaft, an output shaft and intermediate shaft rotatably supported. Multiple pinion gear pairs are supported on the shafts. Two adjacent pinion-gear pairs are associated with two speed ratios. A planetary gear unit, including a sun gear, ring gear, and a set of planet pinions rotatably supported on a carrier, has its input connected to the intermediate shaft and its output connected to the output shaft. Each forward pinion-gear pairs is releasably coupled to one of the intermediate shaft and the output shaft.
