Abstract
A gear transmission has a synchronizing arrangement associated with a helical gear that has end play. The synchronizing arrangement includes a shift sleeve having internal splines engageable with external teeth of a clutch gear that is an integral part of the helical gear. A torque lock feature is provided by cooperating back tapered torque lock surfaces of the splines and the external teeth of the clutch gear. The internal splines of the shift sleeve and the external teeth of the clutch gear are shaped to accommodate the end play of the helical gear and reduce variation in engagement of the torque lock surfaces.
