Expedition Transmission question HELP

I was driving my wife's Expedition 2000 5.4 engine today and noticed something, not sure if it is anything or not....at around 60-65 (well that is what I was driving it at). I notice that every once in a while the tack would show an increase of 200 or so rpms and then back to normal in a couple of seconds (it in was in overdrive) seems like I could feel a shift just not sure. I do know it was not shifting out of OD as in down shifting....What the heck is it? Anything to worry about? no other tranny issues. Thanks

That's the torque converter locking and unlocking. It's normal.
