I'm going to give this a bump in case some folks missed it. We've got some really knowledgeable guys and gals here who are more than willing to help - they just might have missed it.
Oh and I case I haven't done so already (BUSY week) WELCOME to Powerstroke.org!

Oh and to get a better idea of the problem - when you romp on it the RPM's go up and she doesn't shift until you back out a bit but under normal acceleration she shifts fine?
I know mine started doing that after I loaded the Predator tune on her - after about a week of running detuned. I was three updates off on my Predator and one of the updates addressed a "shifting problem". I updated it and re-tuned and she's running better than ever. Are you tuned by chance or stock?

Not trying to be a smart guy, but #1 check the level of the fluid, Always look for the simple things first! I know several stories on fluid levels.

You running stock, or are you tuned and did you buy her new or used? Just curious because I had the same problem last week and it was my tune.
I'm by no means the Tech here I'm just trying to figure out what ya got. The smart guys will be along here in a bit to help out.

it really acts up when the tuner is on. on stock setting it acts up alittle bit but shifts. i bought the truck new.

What kind of tuner are you running? Updating my Predator to the latest tune fixed my problem and it was exact symptom you described - although I didn't have the problem under stock that I can recall.
