I have an f150 5.4 with 104K miles that has I believe to be a 4R75E transmission. works great until 40 mph and a load like a hill or pulling a trailer then it is like the truck is stuttering but the engine check out fine. I have had several mechanics look at the truck and can find nothing wrong. any ideas?

With a 100K on the clock, you might have an engine misfire. Could be time for plugs and coils.
