When the notable drivetrain manufacturer, TREMEC, unleashed its big product reveal at SEMA just days ago, we knew it would take the Corvette enthusiast community by storm. This wasn’t just your ordinary “we’ve got something new” product introduction, but a 6-speed MANUAL — yes, third-pedal manual — with the same mounting points as the eighth-generation Corvette’s automatic DCT. The speculation that this manual transmission may be slated for the C8 Grand Sport only added fuel to the fire.
While the C8 has exceeded its mid-engine expectations and proven to be a sales success (now surpassing C7 production), GM’s failure to offer a true manual transmission has been a sticking point for some enthusiasts. Additionally, the C8’s TR-9080 dual-clutch transmission, also made by TREMEC, has received some criticism, with owners complaining about erratic shifts, thrown codes, and inconsistent service messaging for the DCT’s hard-to-reach fluid filter.
