Here's a quote from the Edmunds review of the 2002 SLK 32 AMG, which has basically the same transmission as the SRT6:
"The transmission deserves mention in that not one of us hard-core enthusiasts (who think a real sports car should have a manual gearbox) minded the automatic at all. In fact, we liked it, a lot. Upshifts were lag-free and firm, yet not jolting. And dipping into the throttle brought quick downshifts that meant an instant burst of power was always available. Additionally, the autobox is programmed to downshift when braking, much like a good driver with a manual, so as to afford engine braking before entering a turn and the right gear when powering out of it."
Those differences are typical for the AMG variants, which are indeed tuned differently than the standard models. Why not let the auto do the work itself and see how you like it? And remember - these transmissions are adaptive, so they will learn and adjust to your habits. Good luck.
