Americans don’t quite share the love affair with dual clutch transmissions like the rest of the world does. The function and feeling associated with them have never been truly accepted by the general buying public.
However, Tremec has announced its new TR-9007 DCT, and it could mean a new option for General Motors. Even though Ford and General Motors have recently finished development of their own ten-speed automatic, a dual-clutch transmission offers benefits of its own.
It’s fast, accurate, and has been developed exclusively with performance and fuel efficiency in mind. Tremec states the seven-speed DCT can handle up to 664 lb-ft of torque and supports a maximum of 10,000 RPM. Meanwhile, the gear ratio spread sits at 5.6, geared towards (pun intended) performance.
Even though this is the official announcement, this isn’t the first we’ve heard of this gearbox. In fact, this seven-speed DCT was reportedly in development alongside the often-rumored, mid-engine Corvette.
The initial report mimics these official specifications, too, surrounding its application in a mid-engine Corvette. Better yet, Tremec tapped its now wholly owned Hoerbiger Drivetrain Mechatronics to oversee development of this transmission. If you’re not familiar, HDM has been responsible for the units found in AMG, Ferrari and McLaren vehicles.
