Features at a Glance:
• Continuous torque over a wide ratio range allowing high performance driving and efficient highway driving
• Over-torque shifting with torque boost for performance launch
• Offered with mechanical or electronic limited slip differentials
• Torque capacity to 800 Nm (590 lb-ft)
• 7,500 RPM maximum input speed
• ISO 26262 and ASIL-D safety standards compliant



Am I missing something here. 2nd line from the bottom states max rpm is 7500, meanwhile the LT6 redlines at 8600.

Well, this flyer was before the LT6 (date is 2019 actually at the bottom of the page). He did ask about the "standard" DCT. I believe that the transmission in the Z06 has been beefed up a bit to accommodate the higher RPM.

Adding to post 5, here are the Z06 upgrades. In addition to beefed up components, it mentions the "track ready oil level - 2L extra not needed." To be clear about that, it does not contain 2 extra liters of fluid. As Josh Holder explained, the case and pan were modified to better hold the oil near the pick up point. And, that particular change, introduced in the 2023 Z06, was also introduced in the late 2023 SR.

Thanks for clearing that up. I didnt notice that tiny 2019 on the bottom of the page. Eyes arent as good as they used to be.
