ABSTRACT:
A multiple-speed ratio transmission mechanism for an automotive vehicle includes a torque input shaft, an output shaft, an intermediate shaft, these three shafts rotatably supported on a common axis, and a countershaft mounted parallel to the other shafts. Multiple pinion-gear pairs are supported on the three coaxial shafts and countershaft. 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 the output connected to the output shaft. Synchronizers drivably connect a member of the pinion-gear pairs to one of the shafts. A shift mechanism transmits motion of a shift lever to shift forks that move synchronizer sleeves into engagement with the selected gear.
