ABSTRACT:
The present invention is a transmission having a two part shift shaft. The spur gear supporting portion of the shift shaft is received by bearings of the housing at its two ends and is made of a relatively strong material for supporting the load of the spur gears. One of the bearings is formed in an internal wall of the housing to support the proximal end of the shift shaft. The shift collar supporting portion of the shift shaft supports the shift collar and is axially aligned with the gear supporting portion. A projection of the shift collar supporting portion engages a recess in the gear supporting portion to axially align and properly position the shift collar for operation of the shifting mechanism. The shift collar supporting portion is made of a less expensive material than the gear supporting portion, thus reducing the overall cost of the transmission.
