I think HOPSNO is looking for a faster shifting transmission? I think before you do a transmission swap try a new street Valve body by VRP. This modified valve body specifically for the the 722.6 transmission really increases the speed at which the transmission will shift at both normal driving and WOT. I have replaced mine and I am still evaluating it as I have reset my adaptive transmission learn mode. I will do a write up here after I have put a few hundred miles on it. But first impressions is that it shifts as fast or faster than my 722.9 non AMG transmissions, with no TCU tune. If you want to know more about the valve body look on YouTube and search for legitstreetcars, Alex Palmerie. Alex has a good evaluation of two valve bodies for his E55. I feel as if I am getting similar results. I’ll write my evaluation up shortly and share it here.
