Sounds like we're on for a show! The Amsoil ATF fluid really seems to smooth out shifting, on other cars we've done over the years. Including another performance built trans (700hp rated) in our customers B5 S4 2.7TT.
Sure, we can do the fluid flush and gasket service next week sometime. Be interesting to see how the current fluid looks once drained out and if there's any-- or how much-- new trans break-in debris in the pan.
