A Manual C8 Corvette Is Finally Here, But The Swap Costs More Than The Car Itself
Peitz Performance Tunes showed off a fully functional manual-transmission C8 Corvette at SEMA 2026 this week, and the Texas shop did something Chevrolet has flatly refused to do since the mid-engine car launched in 2020: give it a clutch pedal. The build uses a Tremec TR-9060 six-speed transaxle rated for 1,000 lb-ft of torque and 8,600 rpm, paired with a custom MoTeC control system that lets the car keep its factory features while adding rev-matched downshifts and no-lift upshifts.
The bigger story is the price. Peitz lists the complete conversion package at $74,528.99, which is more than the $72,495 starting price of a 2026 Corvette coupe. You still have to supply your own Corvette . Spend $74,528.99 on the swap and the price of a new C8, and the total still undercuts the cheapest manual Porsche 911 on sale.
Why Retrofitting A Manual Into The C8 Was So Hard
Chevrolet built the C8 Corvette around its eight-speed dual-clutch automatic from day one, and that decision touches far more than the transmission tunnel. The car’s engine management, chassis controls, shift strategy, and clutch logic were all designed with the DCT in mind, and GM has made the C8’s computers notoriously difficult to modify. Swapping in a true manual meant Peitz had to solve every one of those systems from scratch rather than simply bolting in a new gearbox.
The kit pairs the Tremec TR-9060 transaxle with a custom cable-driven shifter adapted from a Porsche aftermarket part, a clutch pedal sourced from a Cadillac CT4-V Blackwing, and a new flywheel and clutch setup. A pair of MoTeC controllers, an M182 engine ECU and an M150 transmission controller, handle the electronics so the Corvette doesn’t throw dashboard errors and still supports features like automatic rev-matching, ignition-cut upshifts, and anti-lag tuning.
The Math That Makes This Swap Make Sense Anyway
Buy a new C8 Stingray at sticker and immediately hand it over for the conversion, and the combined total still comes in well under the cheapest manual Porsche 911 available. The 911 T starts at $150,350 with destination and makes 388 horsepower. Matching the Corvette’s roughly 500 hp output means stepping up to a Carrera S, which starts at $169,450. Even with a brand-new donor car in the mix, the manual C8 route is the cheaper path to three pedals and comparable power.
That comparison is likely the point. Peitz isn’t pretending this is an impulse buy, but against the only other way to get a stick-shift car with this kind of output, it holds up.
What’s Confirmed, And What’s Still Coming
The SEMA car is real and running, but it isn’t a finished production package yet. Peitz says the MoTeC electronics package will reach final form in the first quarter of 2027, with the complete transmission kit targeted for July 2027. Tremec, which first showed the TR-9060 transaxle at SEMA in 2025, expects to have transaxles in production by next summer.
Chevrolet’s position on a factory manual hasn’t moved. C8 executive chief engineer Tony Roma shut down manual rumors earlier this year, and the automaker has pointed to low demand and the mid-engine chassis’s structural constraints as reasons it walked away from the row-your-own gearbox after the C7’s run ended in 2019. Peitz and Tremec just spent a year proving the engineering problem was solvable. Whether that changes anything in Bowling Green is a separate question entirely.
