Transmission Jump at 45mph
Does anyone have any idea why the transmission on my '04 f150 pickup jumps, skips, at 45mph? It always does this and particularly on cruise control. If my foot is near the accelerator at 45, the transmission snatches. If it is on cruise control, it does it alone. I have touched it with such smoothness when accelerating that it should lull it to sleep, but it still jerks. ONLY at 45 mph!
The dealership technicians say nothing is wrong, they cannot get it to do it when they drive it, but it has done it with everyone in my family.
