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.

A gear shift mechanism for engaging the various gears of a multiple speed ratio manually operated transmission comprising:
- a selector shaft rotatable for selecting gear shift planes and axially displaceable for engaging a selected gear in the selected gear shift plane;
- a selector finger fixed by a hub to the selector shaft, extending radially from the selector shaft, having detent recesses spaced along the axis of the selector shaft corresponding to a neutral position within a gear shift plane and the gear engagement positions within the gear shift plane;
- a check plate rotatably mounted on the selector shaft and fixed against axial displacement, located for contact with the selector finger as the selector shaft rotates, having a hub surrounding the hub of the selector finger;
- detent means for resiliently, releasably engaging the detent recesses
