CAMARO6 - View Single Post - Where is the 7 speed tranny on the ZL1/ZL1 1LE?

I was initially surprised the 7 speed was not offered in the SS, since the Camaro usually gets the same powertrain as the Corvette (after it debuts on the Corvette). I suspect the main reason is that the bigger/heavier/less aerodynamic camaro had more trouble pulling a 0.42:1 7th gear, specifically on the EPA certification cycles. I'm sure the engineers analyzed a benefit (CAFE / CO2) vs. cost and made a decision.

Another factor may have been that the TR6070 is about 1.65" longer than the TR6060 - it's possible it simply did not fit.

I'd be interested in Al and team's feedback on this one, but only after a couple other questions get answered that I consider higher priority.
