I have a 2003 Lincoln ls 3.0
Po755 po743 po760 po132 po750 po966 p2196. 2003 Lincoln Ls v6 3.0 engine it doesn't shift until it hits 4000 RPMs. I went to a dealership and they said that it was my engine so I had the engine replace. After the engine was installed my Lincoln Ls still wasn't shifting right so I put a odb machine on it. All the transmission codes came up there was at least 10 to 12 odb codes that was for the transmission .. These codes didn't come up before my engine was replaced. It doesn't shift correctly still . I believe it goes to first gear to fourth gear . It has no power after first gear . I would like to be pointed in the right direction what the possible problems could be . Or what I should check.? I'm very frustrated I took the car back to ford to have it diagnosed again and still lost for answers because the only thing they told me is it could be the wire harness ?? I had them stop because after 2 hours with no answers and 180 bill they still couldn't give me a diagnosis .. Can anyone lead me into right direction on where to start ???
