Autocrossing C-6 autotranny w/2.56 axle ratio??

[era39]

I have successfully autocrossed with automatic transmission Vettes since 1974 and I'm thinking of upgrading from my '98 C-5 to the C-6. How well does the 6-speed automatic with the paddle-shift and a 2.56 rear axle ratio do against the 6-speed manual with a 3.42???? I would have the Z51 option on the C-6.

Ed,

I've never auto-crossed my (or the Wife's, depends who your talking to) C6, nor do I ever plan to. But I do have the paddle shift and I have played around with it. I think it would take some getting used to. Driving a stick, when you bang the gear its there. Driving my C6, I've noticed when you are trying to drive hard and you hit the button, it takes about a second before it shifts. For me, this delay would take some getting used to. The paddle shift is NOT instantaneous.

Corvette Magazine had an article a while back comparing times between a manual and a paddle shift car - on a solo/autocross course, the paddle car was faster - on a road course, the stick was faster.

I've tried mine on both and can't complain. Just like anything, practice makes perfect. Leading the shifts is required as the paddle shifts are not instantaneous.

I hear the shift time can be shortened by tuning. Not sure though. I have an MM6 tranny.

I have found that I don't shift that much in autocross. I used to run most of the course in 2nd in my '97 A4. I also run most of the course in 2nd in my Z06. So I see the driving accuracy, braking and turning skills as more important than shifting. Just my $0.02
