Could be tune, different tire sizes (still tune related), sucking the pan dry, or 3-4 clutch packs on their way out, but they should die pretty quick if they're slipping that bad.

Have you changed anything at all? Stall, Shift Kit? If everything is stock, I would say Clutch Packs as well.

Well if you done any mods I would certainly look at tuning, However I would also look at fluid condition and smell, How many miles on the trans?
