Probably an improperly assembled clutch.  The OEM plate set includes one friction plate with a larger ID in order to accommodate a small Belleville spring and a thrust ring.  These serve to make the clutch engage more smoothly.  Items 12, 13, and 14 here: https://www.thumpert...1640_clutch.gif

 

The driven gear/basket assembly has a torsional damper built into the hub of the gear.  If there is any rotational free travel between the gear and the basket, that damper is bad, and could be contributing.

I had the same problem on my 99. My problem was the basket taking a beating and the groves were .03-.080 deep lol
