Abstract
A gear shift mechanism for a manual transmission includes a shaft axially movable for selecting shift planes and rotatable for engaging the gears defining the shift planes. The shaft is held in a reference shift plane by two helical springs. A finger, fixed to the shaft, carries a cam defining detent surfaces engaged by a spring-loaded catch stud. Shift fork rods support shift forks which have arms formed with grooves extending toward a locking plate that is moved axially along the shaft by the shift finger. The locking plate blocks engagement grooves of the unselected shift forks.
