First I would recommend retrieving codes for both engine and trans. write it down. try erasing codes. See what doesnt erase or comes back right away. There should be no reason to have to see a dealer over a transmission replacement. The rom (2in square block on the valve body) should have been transferred over to the donar tranny and probably is your problem. P1825 I think. If you no longer have it , you can get this to work but it sometimes is very stubborn . Try again erasing codes disconnect large square plug on trans erase again, plug back in erase again check codes.
