Ha! I actually am having this exact issue, decided to see what info I could find.
It's like a surging, most noticable around 1700 rpm, it dips and then catches up.
My first thought was TCC solenoid, since the issue goes away when overdrive is turned off. It COULD be an ignition issue, but I've got a reman engine with new coils, so I'm leaning towards transmission. I put a Motorcraft MAF in last summer after getting codes for that. I'm not opposed to trying the friction modifier, honestly. I just don't want to drop the pan in this snowy weather.
Sorry for resurrecting an old thread, but I can at least say I didn't start it!
