2005 5.4 bump
I'm having a problem with a bump between 45 and 50 miles an hour or 1500RPM. As it goes through acceleration and get to this point it will bump 2 or 3 times pretty hard. I can turn overdrive off and it doesn't do it. There is no code, check engine light nothing. At highway speed it runs fines.
Am I looking for an ignition problem or a transmission problem? Need a starting point please.
