Abstract

A gear-change mechanism for a conventional two-range speed-selection transmission comprises a gear-shift lever which is coupled to a shaft in a housing, this shaft carrying a pair of strikers which engage elements connected to the shifting rod. According to the invention, the striker forms a packet with a plurality of check plates disposed between and in front of and behind the striker plates and held on the shaft for axial displacement therewith. The check plates are guided in the housing so that they cannot rotate with the shaft.
