Abstract
A manual shift transmission having multiple input and output portions is provided with a control having input and output shift rails. A laterally movable control shaft extends axially through cutouts in respective shift rails and carries cams adapted to cooperate with cam follower surfaces on corresponding cutouts to effect rectilinear movement of the shift rails upon rotation of the control shaft. The cams are arranged on the shaft so that the shaft may be positioned to place respective cams in register with the input and output shift rails while all other cams are out of register with the rail cutouts. The shift movement of respective output and input shift rails is overlapped during the rotation of the control shaft to decrease the throw of the shift lever.
