Tuners Just Built The Stick-Shift C8 Corvette Chevy Said Would Never Happen

Traditionalists mourned the death of the stick shift in America's current generation sports car, but one aftermarket team has successfully mated a Tremec six-speed to a C8 Corvette and is readying it for production.


When Chevrolet rolled out the C8 generation, it drew a hard line in the sand, insisting that the platform was built exclusively for a DCT, thereby leaving zero room for a traditional clutch pedal. Purists grumbled, but what could you do? Rowing your own gears has pretty much become a thing of the past. 

Enter Peitz Performance Tunes, a shop that has pulled off what has so far been considered wishful thinking. Collaborating closely with component heavyweights, it managed to squeeze a Tremec TR-9060 six-speed manual transaxle into the C8 layout. Of course, shoehorning a manual gearbox into a car whose entire nervous system was coded for an automatic is a headache all by itself; the real nightmare lies in tricking the car's computers to cooperate with the Tremec.

So what Peitz did was deploy MoTeC controllers, specifically an M182 ECU paired with an M150 transmission control module, which handles the dialogue between the engine and the new gearbox. This approach allows for niceties like automatic downshift rev-matching and no-lift upshifts. The team also integrated a modified clutch pedal assembly borrowed from the Cadillac CT4-V Blackwing to complete the package. 

Naturally, "curing" the C8's automatic-only ailment comes at a price. The complete turnkey conversion package is listed at $74,530. That's the same price as a brand-new Corvette Stingray coupe straight from the showroom floor, so is the Peitz stick-shift package (about $150,000 all in including the donor car) actually worth it? For the same money, one can get themselves into a 911 T with a 6-speed manual, but arguably the Porsche is less "special."

That being said, as much as the Peitz Corvette wowed the crowds at the recent SEMA show, the car is still a prototype. The tuner says a lot of work is still needed to finalize the tuning of MoTec controllers and Tremec transmission, as well as gussying up the interior before it can call the modded Corvette production-ready. Peitz expects to have the transmission kit ready by July next year, while Tremec is targeting next summer to begin production on the transmissions.
