Title DAMPER ASSEMBLY FOR SHIFT LEVER MECHANISM Abstract of the Invention A compound shift lever mechanism employs a noise and vibration damper assembly for isolating an upper shift lever from a lower shift lever of a transmission. In a preferred form, the levers are held in spaced, coaxial alignment for unitary movement in a plurality of planes by a damper which comprises two parts. The first part is a cylindrical elastomeric sleeve defining axially spaced female end portions comprising bores which frictionally overlie and snugly encase the two lever end portions which extend thereinto. The second part is a cylindrical metallic shell which circumferentially encapsulates the elastomeric sleeve which contains the respective ends of the upper and lower levers. The shell thus radially encapsulates both of the end portions, as well as the sleeve, which incorporates a midportion containing a radial internal barrier to prevent direct physical contact between the extremities of the levers. Finally, spaced female ends of the shell are crimped radially inwardly against the female end portions of the sleeve and, in turn, against both lever end portions, to frictionally retain the end portions in spaced, coaxial alignment.
