A gearshift lock for the shift mechanism of a manually operated multiple speed ratio transmission includes a selector shaft rotatable by a gearshift lever under the control of the vehicle operator, a selector finger movable within slots formed in a base plate, the slots being defined by the various positions of the gearshift lever that correspond to speed ratios of the transmission. A spring-loaded rotatable locking cam mounted on the gate plate cooperates with a finger carried on the selector shafts to prevent backward shifting movement from a forward gear position into the reverse gear position and to guide the selector finger into the adjacent gearshift slot. A base plate pivots on a pin fixed to the gate plate against the force of a legged spring to produce a sensible indication to the vehicle operator when greater force is required to move the gearshift lever. |
