What the first Gen DCT should have been
Here is the new M1M DCT the 2023 Z06 has

Corvette chief engineer Jason Holder confirmed the improved transmission for the 2023 Corvette Z06 during a presentation.
According to Holder, this version of the transmission will feature an upgraded clutch pack for increased torque capacity, along with a strengthened casing to handle larger lateral loads.

The bell housing was also redesigned to accommodate a larger oil sump,
allowing Chevy to ship the Z06 with track-ready oil levels.
On the C8 Corvette Stingray, drivers are advised to add an extra two liters of oil if they plan to take the vehicle on a track to ensure the engine received proper lubrication under high load.

The Corvette Z06’s eight-speed transmission will also feature larger diameter output shaft flanges to support the model’s high-strength half shafts,
along with a 5.56:1 final drive ratio, which is about seven percent shorter than the C8 Corvette Stingray’s factory gearing.

The Tremec TR9080 eight-speed dual-clutch transmission on the C8 Corvette Stingray is tagged with RPO code M1L,
however, this improved version for the Z06 has a different RPO code of M1M.
