A transmission assembly for a vehicle including a transmission casing, at least two generally parallel transmission shafts rotatably supported within the casing, gears coacting between the transmission shafts for defining plural drive paths having different speed ratios, axially shiftable clutches coacting with the gears for permitting selection of different drive ratios between the transmission shafts, and a shifting and selecting mechanism for the clutches. The last-mentioned mechanism comprises a shift and select unit having a shift and select shaft which is rotatably and axially slidably supported relative to the casing. The shaft projects into the interior of the casing in generally perpendicular relationship with respect to the rotational axes of the transmission shafts. The shift and select shaft has a shaft end portion which projects outwardly through the wall of the transmission casing for a selected axial extent. A shift lever is nonrotatably coupled adjacent the outer end of the shaft end portion and projects radially thereof exteriorly of the casing for effecting angular displacement of the shaft. A select lever is rotatably supported but axially coupled to the shaft end portion adjacent the outer end thereof for effecting axial displacement of the shaft. |
