Rear End Slip?

[ChevyHDGert]

Starting from a dead stop, my truck seems to slip as if my wheels are slipping on water or like I am peeling out or something. The truck just stalls a bit and then it takes off. Anyone else have this? This is with the 4.10 rear end.

Ryan has a thread going in "light-duty" about an intermittent neutral problem.  He has a 4L60 and the Hd's have a 4L80 tranny so I don't know if it would apply...
