DO try it on Level 1, John, and let us know what happens. I've never experienced this in my truck, not with the original canned tunes or now with custom ones. I wonder if the TC is sort of trying to make up its mind to lock or not? Your excellent description does seem to point to the transmission though.
Are you in drive when this happens, or do you have the O/D locked out, so it's prevented from going into 4th? The only time I lock my O/D out is going up steep hills where it "hunts" or going down when I want engine braking.
