Truck runs good cold, shifts good, no problem. After it gets warm when going up hills, passing even when giving little more throttle it seems to slow like it sticks between third and overdrive. when I let off gas it will shift into overdrive and resume okay.
Even then when I take off at red lights it hesitates between gears.

Thanks, that was my next move. I have read up on where the wiring harness could be the problem.
