Tremec 6 speed manual with C8 mounting points

Car and Driver July 2019

"Executive chief engineer Tadge Juechter told Car and Driver that part of the reason is the desire to not breach the mid-engine C8's central tunnel: "That tunnel is the backbone of the car, and if you break the backbone, you lose a lot of structural efficiency. With a shifter, you have to have a big hole in the tunnel for the linkage to go through."

I'm not so sure you'd have to touch the tunnel. There is shift by wire or cables which could run along the outside of the tunnel. In fact the new dash seems more conducive for a shifter. Hydraulic clutch lines could be run that way also.
 
In a scenario: DCT dies in a C8 that is out of warranty and the bill is 10s of thousands of dollars, there will now be an option to convert to a true manual for potentially less money
Ya, I bet someone will bring out a kit to adapt it all sooner or later.

Maybe they will, maybe GM won't, and as much as I love rowing gears, I doubt it will be faster but possibly more fun.
I would have to think hard about this option after using this DCT in track conditions. Don't see how the manual will top it performance wise.

Whoever designs the programming that would be required, as so much of the handling nannies and performance aspects are tied to the DCT currently. It would not be a easy fix for aftermarket companies.

But with Tremec doing the research and development on this transmissions, maybe Tremec are dangling the proverbial carrot in front of GM for the C9 as a option. It is specifically designed with C8 in mind, as they claim in can handle 800ft/lbs or torque and up to 1000hp. No ELSD.
It also revs out to 8600rpm so it was also designed with Z06/Z07 in mind.

Absolutely no doubt. It's sheer enjoyment factor. I enjoyed the control I had with the pure manual tranny. Picking any gear I wanted at any engine speed regardless of consequence. I felt more connected to the car. It wouldn't be faster, just more fun.

I think in the press release they did say shift by wire......
 
How many would trade their DCT for a manual? The only manual I would get just because I haven't had is a sequential.
I made a deal with the devil ... er ... I mean my wife let me buy a C8 only because it was a DCT. So, no. I'd love a Stick car, but it's not in the cards.

From the Tremac article "The TREMEC manual 6-speed transaxle maintains the TR-9080 DCT unit’s packaging envelope and mounting points to help builders design things around the transaxle for optimal suspension fitment and travel maximum handling capability. Gear shifts are controlled via cable that connects to the shift mechanism on the left side of the transaxle"
