A pile driving transition piece. The transition piece avoids the shock loading in the stabbing points of pile driving transition pieces that otherwise would be induced when the pile driving hammer strikes the transition piece. Avoiding the shock loading prevents the characteristic fatigue cracks from forming in the stabbing point and the consequent failure of the stabbing points from rapid growth of the fatigue cracks.
