ABSTRACT:
An arrangement for dampening a transmission synchronizer. A plurality of T-shaped shoes are disclosed for assembly on the jaw toothed shoulder of the synchronizer main gear. The shoulder has a plurality of chordal flats with a radial bore formed therein. Each T-shaped shoe is molded of resilient material and includes a cross head portion and a stem for reception in its associated radial bore. The synchronizer stop ring has selected individual ones of its internal teeth omitted creating slots defined by the omitted tooth together with the adjacent root spaces. The cross head is sized to snugly contact the opposed flanks of the adjacent stop ring teeth. By urging the stop ring internal teeth into a neutral centered position with the gear teeth the invention obviates stop ring rattle by eliminating play between the stop ring and the main gear.
