Peitz Performance Tune has developed a manual transmission conversion for the Chevrolet C8 Corvette. The upgrade is currently compatible exclusively with the base Stingray model. According to company founder Alex Peitz, the modification is expected to cost between $60,000 and $70,000, excluding the base vehicle price.
The conversion process involves installing a Tremec-supplied transmission, a clutch, a shifter, and additional hardware. The team utilizes a MoTeC control unit to bypass the factory software limitations of the C8. The interior is also modified with a custom center console that integrates the new shifter while retaining existing drive-mode selectors and buttons.
Peitz Performance Tune plans to manage all installations internally until the package is ready for broader distribution. Tremec is scheduled to begin production of the manual transmission in mid-2027. Chevrolet has previously stated it has no plans to offer a manual transmission for the C8, citing low demand for manual gearboxes in previous models.
