Actually you are correct. I assumed they used the MB 5 speed auto like in there other SRT models and models with the V8 engine, 300C Hemi+ and the Magnum Hemi+ and the Crossfire. They all had MB 5 speeds trannies in them, well when Daimler owned them they did at least. Considering the driveline and underpinings were from an old E class and SLK for the Xfire.
