TREMEC And Peitz Performance Bring The Six-Speed Manual C8 Corvette To Life

As enthusiasts, we’ve heard a lot of back-and-forth about a manual transmission for the eighth-generation Corvette. Officially, GM has moved past offering a manual option for the car for a variety of good reasons. For starters, the dual-clutch TR-9080 the company developed with TREMEC is a truly revolutionary piece that makes the car much faster. Secondly, demand for three-pedal Corvettes, and three-pedal cars in general, is going the way of the Camaro. That said, like the Camaro, the three-pedal Corvette isn’t as dead as we might think.

It Does Exist

At SEMA 2025, TREMEC debuted a six-speed manual transaxle for the C8 Corvette. The idea was to eventually develop an aftermarket option for enthusiasts who still want the thrill of three pedals. In early 2026, Corvette leadership reiterated its logical plan not to certify a manual gearbox for production.

That brings us to SEMA 2026. Among the fleet of killer rides TREMEC displayed at its booth, one was particularly interesting to Corvette and LT fans. That car was Peitz Performance’s Time Attack C8 – a legit pairing of the six-speed transaxle TREMEC debuted at SEMA 2025 and an eighth-generation Corvette.

Peitz Performance, Naturally

According to Alex Peitz, installing the transmission itself was actually one of the easier parts of the project. TREMEC designed the six-speed transaxle with essentially the same dimensions and mounting points as the factory TR-9080 eight-speed. As a result, the team already knew the gearbox would physically bolt into the Corvette.

The real challenges involved the components Chevrolet never intended the C8 to have: a clutch pedal and a manual shifter. To address the shifter, Peitz Performance started with an aftermarket Porsche assembly. However, making it work in the Corvette required extensive modifications, and by the time the team finished, Alex estimated that only about 20 percent of the original shifter remained.

Creating a clutch pedal that worked well was no less challenging. Rather than fabricating everything from scratch, the team started with a pedal assembly from GM’s own Cadillac CT4-V Blackwing. Like the shifter, the pedal required substantial modifications, leaving only an estimated 10 to 20 percent of the original component intact.

Your Manual C8 Corvette Awaits

Now that the team has worked through the initial challenges of getting the prototype operational, Peitz Performance plans to revisit both components and develop more production-friendly versions. More importantly, Alex confirmed that the company intends to offer the conversion as a complete package for Chevy owners who want to trade their dual-clutch transmission for the vastly different feel of a manual C8 Corvette. You read that right: Peitz Performance isn’t simply demonstrating a one-off prototype; the company intends to develop a repeatable solution for customers.

While there’s no denying that the C8’s dual-clutch transmission is an incredible piece of engineering, there’s still something to be said about rowing your own gears. A manual transmission isn’t necessarily about being the fastest anymore. It’s about driver engagement, having complete control over the experience, and enjoying the mechanical connection between man and machine. And for plenty of Corvette enthusiasts, that’s something no paddle shifter can replace. As an official fan of the manual lifestyle, I can’t wait to take a ride in a Peitz Performance 6-speed conversion!
