2015 Chevrolet Corvette Stingray to Receive 8L90 8-speed Automatic Transmission?
2015 Chevrolet Corvette to get 8 speed automatic transmission
LeftLaneNews December 9, 2013 Although the Chevrolet Corvette Stingray launched with a carryover six-speed automatic, the sports car will soon benefit from a new eight-speed transmission, a Society of Automotive Engineers technical paper has confirmed. A preview of the paper, briefly posted to the SAE's website and subsequently removed, revealed that the eight-speed automatic will arrive on the Corvette's options list for the 2015 model year. Dubbed the 8L90, the rear-wheel-drive gearbox will offer an overall ratio spread of 7.0 and a shorter first gear for quicker acceleration. As the current Corvette six-speed automatic is capable of 28 mpg on the highway, the octa-cog unit could boost freeway mileage to 30 mpg or higher - not too shabby for a 455-horsepower performance machine. The SAE paper also notes that the eight-speed will be able to handle torque output of up to 738 lb-ft. That means it could potentially be offered in the next iteration of the Corvette Z06, which to this point has only been available with manual transmissions. Of course, we'll have to wait until next month's Detroit Auto Show to see what Chevrolet decides to do.

I'd like to see the gear shift lever as the 'manual' shifter instead of paddle shifters...
does that put me in the minority? |

I was pretty sure that the 8 speed auto would arrive next year but it's potential to be placed into the Z06 is a big surprise. It will be interesting to see if the auto can make 30mpg in the base model and be placed into the Z06/ZR1 in the future.

Right, I posted the SAE paper on the C5 side. It's unambiguous, the C7 will get the 8 speed. Furthermore, I also posted all the patents GM has on dual clutch tech, and by the looks of that, the Z06 will certainly get one sooner or later.

You'll also find all the patents GM has taken out for dual clutch tech if you scroll down in that thread. ^
