ABSTRACT:
A method and apparatus for shifting gears in a multi-speed manual transmission. Shifting is accomplished through translation of a linear axial movement of a rotary channel cam indexer to an angular rotation of a rotary channel cam. The rotary channel cam has a cam groove supporting cam followers to translate angular rotation of the rotary channel cam to axial movement of a plurality of transmission shift shafts. The positioning of the plurality of transmission shift shafts places the multi-speed manual transmission into a desired gear.
