Default HydroStick failure

After five years of good service the front clutch quit working in the HydroStick of my '59 GMC (no 2nd or 4th gear). I got it out and apart and the front ring land of the oil delivery sleeve is collapsed, preventing sealing to the front hub. The steel thrust washer had "chewed" the face of the delivery sleeve, but I don't know why. Fixing it is a simple matter of replacing the sleeve and washer, but my concern is understanding why it happened. Also, the anti-rotation tang of the washer is chewed away. Anybody ever have such a failure of a DualRange Hydramatic?
