4R100 Tranny clunks into reverse

I ahve a 99 PSD 4x4 with an Auto Trans. When I go into reverse she revs up above 2K rpm then really clunks hard into reverse. Forward gears are fine Torque converter feels fine, Only reverse is acting up moves slow at first, revs up to 2K rpms then hard clunk into reverse, grabs and goes at that point. any ideas?

How does the fluid look? I think the reverse clutch may be gone.

If the fluid is brown or black or has a burnt smell a clutch has been destroyed.
