Hello all. I got an 03 a4 1.8t that's having some shifting issues. When cold it shifts ok but once it warms up it wants to take off in 4th gear. If I shift it over to manual mode it seems ok. From what I've read and been told was a fluid change could help but im not so sure. I would like to get some advice as to what options I have with it and if anyone else has had the same issues. Thanks in advance.
