ABSTRACT:
A manual transmission for an automotive vehicle driveline having four forward driving ratios with torque transmitting gear elements mounted on countershafts arranged in radial disposition and in parallel relationship with respect to a power input shaft, a power output shaft concentrically disposed in the power input shaft whereby the overall axial dimensions of the transmission mechanism are reduced and the gear loads are isolated to reduce deflection and to permit the use of relatively fine pitch gearing and wherein provision is made for mounting the differential gearing within the transmission assembly and for braking the transmission output shafts at a location adjacent the differential side gears.
