As far as the jolting shift is concerned, I do not object to a shotgun type sensation following the downshift of the transmission. What I think speaks for an inferior transmission design is when the transmission then up-shifts and it sounds like you hit a big hunk of metal with a sledgehammer. Not in a thousand years would I justify that design. I would expect nothing less than a refined transmission design with smooth up shifts. As I said, the SL55AMG I had did it perfect. The Corvette Engineers should aspire to that perfection, nothing less (don't try to explain an inferior design away as being exhilarating or cool!).
