This patent describes a gear-change apparatus for a vehicular transmission having forward gear trains each established through an associated synchronizing mechanism, and a reverse gear train established by axial movement on a shaft of a reverse idler gear, an improvement comprising: a cam mechanism having a first cam fixed in place on a reverse shift fork for shifting the reverse idler gear from an inoperative position to an engaged reverse gear train position thereof and, a second cam fixed in place on a forward shift fork for establishing one forward gear train, the first and second cams being arranged such that when the reverse shift fork is moved in a direction which causes the first cam to engage the second cam the forward shift fork is shifted by a predetermined small stroke sufficient for the synchronizing mechanism of that one forward gear corresponding to the forward shift fork to effect only the synchronizing action thereof in response to the movement of the reverse shift fork from the inoperative position of the reverse idler gear to a position immediately before the engaged reverse gear train position of the reverse idler gear.
