As good as the new automatics are, I would go with a T56. I have a new CTS-V w/ the 6 spd auto, its fine for a that type of car but to me, it will never "feel" like a manual transmission car. The only other transmissions better are the F1 in a Ferrari Scuderia or the new double clutch systems in BMW, Ferrari ect. Even the E-gear in my Turbo Lamborghini is slow in comparision to the dual clutch trannies.
