General Motors has shifted production of the eight-speed dual-clutch transmission for the Chevrolet Corvette C8. Starting in 2026, all DCT units will be assembled by Tremec at a facility in Michigan, whereas some output was previously handled at a GM plant in Ontario.

Since the 2022 model year, transmissions were partially manufactured under license in Canada. That program has now ended, with production fully returning to U.S. lines. After assembly, the gearboxes are shipped to the Bowling Green, Kentucky plant where the Corvette itself is built.

This change does not affect technical specifications. All versions—from the 495-hp Stingray to the hybrid E-Ray, as well as the Z06, ZR1, and 1,250-hp ZR1X—use the same Tremec DCT architecture. More powerful variants receive reinforced shafts, an upgraded lubrication system, and strengthened gears to handle higher loads.

Meanwhile, the St. Catharines plant in Canada will focus on producing the next generation of gasoline V8 engines for GM's full-size models. Overall, this move is about logistics and production optimization, not a step back from Canadian manufacturing capacity.
