    Default AOD-E down shift problems

    The trans in the bird has a problem when I get on it and it tries to down shift. The RPMs go to about 5000 then it down shifts and barks the tires. It only does it on down shift. If you just take off its fine. There is no kick down linkage that I found to adj beings its a computer controlled trans.

    I just don't want to break the rear end on the car because its exspencive and a PITA to change out.

    I thought the castings look quite different, and the 4r70w has modified internals. Oh, the AODe seemed to also only have a SB windsor bolt pattern.

    Correct, but the computer controls; for the most part; are the same. When was the last time you did a fluid change? Sounds like somethings stuck in the valve body. I take it that it shifts that high under light loads?

    Yes, going down the road around 65mph and 1/2 throttle to pass some one it will jump way up in RPM. Then kick in and bust the rear tires loose.

    I just got the car in Oct. I don't even know if the fluid has ever been changed. Its still bright red.
