ABSTRACT:
A multi-speed rear wheel drive transmission having synchronizers and a plurality of gears rotatable on the input shaft provides for the elimination of neutral roll-over noise and optimization of common reduced size synchronizers. Gear face widths are also reduced along with shaft diameters to further optimize the transmission design. Towing restrictions are no longer required in vehicles utilizing this design. The input shaft is coaxial with the output shaft and may be connected by synchronizer to the output shaft. A countershaft is in continuous meshing contact with the output shaft. Also disclosed is a device for correcting in-gear rattle, as well as a lubricating pump assembly utilizing an axial bore in the input shaft. Finally, a transmission with a power take-off assembly is disclosed.
