ABSTRACT:
A gearshift mechanism for a multiple speed manual transmission includes a selector shaft, which is rotatable for preselecting gearshift planes and axially displaceable for engaging the selected gear; a selector finger fixed to the selector shaft selectively engageable with grooves on gearshift forks guided on the selector shaft; a check plate surrounding the selector finger and selector shaft pivotably mounted but axially fixed to prevent movement of the unselected gearshift fork; and a spring-loaded detent for engaging recesses formed at the hub of the selector finger.
