I sure hope GM did improve the software and hardware for the manual shifted 6 speed automatic. I drove an '07 with that yesterday and to say the least was totally unimpressed, given the pausing between hitting the paddles and the car responding. Not exactly what I would want on some of my favorite twisty mountain roads down in se KY!
Maybe the GM engineers should try the new MX-5 (Miata) and its 6 speed auto with manual shift: fast, precise and totally responsive to input at any revs. DFO
I don't think the automatic, paddleshift or otherwise, would make a big difference in th e0-60 time since it always takes place in first gear. Thus the shifting of the trans doesn't come into play. Unless there's a different 1st gear ratio on the paddleshift -vs- the other available trans.Wow, 0-60 in 4.3 with the 6spd paddleshift auto
Finally, some performance numbers for the auto.
