Tremec Unveils 6-Speed Manual Transmission For The C8 Corvette At SEMA
With a push towards electrification, driver aids that outperform human reaction times and talent, and lightning-quick dual-clutch transmissions, it’s nice to see a manufacturer still developing parts that may not offer the best possible track times, but triumph in the overall driving experience. Tremec, who are known for performance OEM and aftermarket transmissions, did just that and debuted its latest creation at SEMA 2025: A C8 manual transmission.
A Manual Comeback In The Age Of Automation
As we walked the floor of central hall in the Las Vegas convention center this year for the SEMA show, a stroll past the Tremec booth caught our eye with a billet-cased transaxle that resembled the Tremec TR-9080 DCT out of the C8 Corvettes. But this was no automated dual-clutch transmission; it’s a 6-speed manual transaxle Tremec developed that will be for sale in 2027.
A Familiar Shape With A Very Different Purpose
The case is machined from billet aluminum and closely resembles the case for the 8-speed DCT in the C8, including the bellhousing bolt pattern, rear mounting locations, output shaft mounting flanges, as well as its length, width, and height. Inside is where things are a little different from the DCT. First, the input shaft is similar to what you would find on a 6-speed magnum.
Built For Big Power And Serious Drivers
The gears inside the C8 manual transmission are mostly borrowed from the non-Z51 8-speed DCT, with 2nd through 6th gear, and the final drive and ring and pinion ratios being the same. There is no 7th and 8th gearset, naturally, and the first gear ratio has been changed to be a little taller. Changing the first gear ratio will help with higher-powered applications getting off the line.

Aftermarket Only (Maybe… For Now)
Speaking of horsepower, Tremec states the new 6-speed is capable of handling 1,000 horsepower and 800 pound-feet of torque with engine speed up to 8,600 rpm. When we asked if this would make it into a production Corvette, they were quick to tell us that this is for aftermarket use only (we’re really hoping they’re just not allowed to say). When it comes to clutch pedal and shifter solutions, you’re on your own. Even though the shift mechanism on the transmission is similar to what you would find on other manual transaxles and the clutch slave cylinder is based on an OEM piece, Tremec has no plans to offer the new C8 manual transmission as a complete kit.

Tremec, who are known for performance OEM and aftermarket transmissions, did just that and debuted its latest creation at SEMA 2025: A C8 manual transmission.
A Manual Comeback In The Age Of Automation
As we walked the floor of central hall in the Las Vegas convention center this year for the SEMA show, a stroll past the Tremec booth caught our eye with a billet-cased transaxle that resembled the Tremec TR-9080 DCT out of the C8 Corvettes. But this was no automated dual-clutch transmission; it’s a 6-speed manual transaxle Tremec developed that will be for sale in 2027.
A Familiar Shape With A Very Different Purpose
The case is machined from billet aluminum and closely resembles the case for the 8-speed DCT in the C8, including the bellhousing bolt pattern, rear mounting locations, output shaft mounting flanges, as well as its length, width, and height. Inside is where things are a little different from the DCT. First, the input shaft is similar to what you would find on a 6-speed magnum.
Built For Big Power And Serious Drivers
The gears inside the C8 manual transmission are mostly borrowed from the non-Z51 8-speed DCT, with 2nd through 6th gear, and the final drive and ring and pinion ratios being the same. There is no 7th and 8th gearset, naturally, and the first gear ratio has been changed to be a little taller. Changing the first gear ratio will help with higher-powered applications getting off the line.
Aftermarket Only (Maybe… For Now)
Speaking of horsepower, Tremec states the new 6-speed is capable of handling 1,000 horsepower and 800 pound-feet of torque with engine speed up to 8,600 rpm. When we asked if this would make it into a production Corvette, they were quick to tell us that this is for aftermarket use only (we’re really hoping they’re just not allowed to say). When it comes to clutch pedal and shifter solutions, you’re on your own. Even though the shift mechanism on the transmission is similar to what you would find on other manual transaxles and the clutch slave cylinder is based on an OEM piece, Tremec has no plans to offer the new C8 manual transmission as a complete kit.
