Abstract
Apparatus for shifting a transmission including a shift collar axially movable on splines on one rotary member for engagement with the splines of an adjacent rotary member to provide corotation of the rotary members, the shift collar and the adjacent rotary member having engagement means responsive to thrust applied axially to the shift collar for initially synchronizing rotation of the shift collar and the adjacent rotary member and then for guiding the splines of the shift collar onto the splines of the adjacent rotary member, the engagement means being constructed and arranged so that the parts to be synchronized can be guided together from positions of wide angular misalignment to positions of proper axial alignment for completing the shifting operation.
