Tremec will supply manual transmissions for the new CT4-V Blackwing and CT5-V Blackwing.
Cadillac has been slowly trickling out new details about the anticipated new CT4-V Blackwing and CT5-V Blackwing, marking the triumphant return of Cadillac's fabled V-Performance cars. Last month, manual lovers rejoiced when Cadillac confirmed both models will be equipped with a six-speed manual transmission as standard or an optional ten-speed automatic gearbox.
This will also be the first time Cadillac has offered a manual transmission since the ATS-V was discontinued. According to GM Authority, the Blackwing manual transmissions will be supplied by Tremec. The Michigan-based company is certainly no stranger to supplying gearboxes for high-performance cars, having supplied six-speed manual transmissions for the CTS-V, ATS-V, and various Camaro and Corvette models.
It isn't yet known which Tremec transmission will be used, but the publication claims the unit being developed for the CT5-V Blackwing will be more robust to accommodate the car's higher torque output.
Under the hood, the CT4-V Blackwing is expected to pack the same 3.6-liter twin-turbo V6 as the ATS-V generating 464 horsepower and 445 lb-ft of torque. The CT5-V Blackwing, on the other hand, is expected to utilize a supercharged 6.2-liter LT4 V8 rated at 640 horsepower and 630 lb-ft of torque, which is the same engine used in the Chevrolet Camaro ZL-1. It's not clear if both Blackwing models will get the same Tremec transmission, but the publication speculates there will be two different Blackwing manual transmissions.
One likely candidate is the TR-6060 as it can handle up to 650 lb-ft of torque. Alternatively, Tremec could be developing an all-new transmission for the two Blackwing models. Either way, purists will be pleased Cadillac is offering the option to row your own gears at a time when manual options are becoming less common.
Cadillac has already confirmed the six-speed transmission will make extensive use of 3D-printing technology, including the shifter medallion. This will be the first time Cadillac has ever implemented 3D printed for a production car. We'll find out more details about Cadillac's collaboration with Tremec when the CT4-V Blackwing and CT5-V Blackwing debut next summer.
