When doing normal driving engine jumps about 500RPM after initial shift to 2, 3, and 4 without changing power to the road. If I get into the throttle it settles back into the gear at a normal RPM, but jumps right back when I let off. Replaced the transmission with a Ford reman from the dealership after finding a lot of metal in the pan during a fluid change. I expected this to clear up with the new transmission, but all that changed is the shifting got smoother. I'm guessing that makes this an electrical issue, but I'm not sure the best path to take next.
