So as i previously posted I just re installed my rebuilt top end engine. But it jerks into almost every gear I guess you can say it shifts hard. The transmission never done that when u pulled the engine out so 2days ago I finished installing the engine and took it for a test drive and I noticed the shiffting issues. I mad some calls and was told to make sure it had enough trans fluid and check for loose or pinched wire. So today I took it to advance Auto to try to get some codes which I did get a few eventhough my check engine light ain't on. But the codes I was given was a po122 and a po113 could any of those be causing the problem?
