A shift lever assembly designed to isolate vibrations including an outer can having a bore and an outer wall, an inner can disposed within the bore, a vibration absorbing material positioned within the bore and around the inner can; and a sleeve extending from the outer wall of the outer can. The method of making the shift lever assembly includes positioning an outer can having a bore and an attached sleeve in a mold, positioning an inner can in the mold, within the bore of the outer can, injecting a vibration absorbing material into the mold, thereby filling the space within the bore of the outer can around the inner can, and allowing the vibration absorbing material to cure, thereby securing the inner can within the outer can.
