ABSTRACT:
A shift linkage is used in combination with a shift lever displaceable in two substantially perpendicular directions and with a transmission having an operating shaft extending along an axis and displaceable axially and angularly to change gears. The linkage comprises a first selecting lever extending radially from the shaft, fixed for joint angular movement with the shaft, and having an outer and forming a plurality of like attachment points and a second selecting lever pivoted on the transmission and having one end engaged with the shaft for joint axial movement while permitting relative angular movement and another end forming a plurality of like attachment points. A two-arm lever carried on the shift lever has offset in the one direction from the lever end an attachment region forming a plurality of like first attachment points and offset in the other direction from the lever another attachment region forming a plurality of like second attachment points, A pair of tension- and compression-transmitting cables each have a sleeve and a core slidable longtitudinally therein and having a pair of opposite ends. Connectors secure one end of one of the cores at one of the first points to the two-arm lever and the opposite end thereof to one of the attachment points of the first selecting lever and secure one end of the other core at one of the second points to the two arm lever and the opposite end thereof to one of the attachment points of the second selecting lever.
