A fluid pressure independent, mechanically controlled dampener for a hydrostatic transmission pump track ring is shown. In one embodiment, two opposing wedge-shaped blocks are biased against each other by a spring-loaded bolt. A pad, axially adjacent the track ring on one side and axially adjacent and held together with one block by a Z-bracket on the other side, is biased against the track ring by pressure exerted through the spring-loaded bolt and wedging action of the opposing wedges. In another embodiment, a spring-loaded piston disposed within a spring housing, exerts pressure against a first pad axially adjacent the track ring to hold the track ring against another pad axially adjacent and opposite the first pad.
