TREMEC Just Released a Manual 6-Speed Transmission with the Same Mounting Points of the C8’s DCT

Despite all the features available on the C8 Corvette, there are some enthusiasts out there who just refuse to come to terms over the lack of a manual transmission. And who can blame them when there is nothing more fun than rowing through the gears of a manual Corvette?
Corvette engineers did look into equipping the mid-engine C8 Corvette with a manual gearbox, but as we’ve heard time and again, it simply came down to economics. By the time the C8 Corvette was in the process of development, GM was already sourcing an advanced dual-clutch automatic transmission from TREMEC and the costs and packaging requirements to do a separate manual transmission would simply make it too costly for the estimated 15% of buyers it would garner.
The Dual Clutch Transmission for the C8 Corvette was developed with TREMEC and the units are built in Wixom, Michigan. That DCT was also a challenge according to Tadge because no one was making an off-the-shelf transaxle DCT with just the right dimensions. “We don’t just find a DCT, an 8-speed DCT that plugs into this architecture with the right dimensions,” he noted.
Now that we are seven years into the C8 era, TREMEC is making news once again as they have just revealed a new transaxle 6-Speed Manual Transmission that offers the same packaging requirements, and more importantly, it uses the same mounting points of the C8. According to the official press release, “Gear shifts are controlled via cable that connects to the shift mechanism on the left side of the transaxle.”
