Exactly. I think it is just the behavior of a powerful clutch. My 2001 cammed Z06 with a Textralia clutch and light weight flywheel behaved the same way. With the power these cars are making today, its tough to make everything completely smooth. I feel like its completely normal.

Above 4K from a stop? 
My 2014 (49K miles) sometimes shudders when taking off from a stop but only in 1st. If I take off from 2nd, no issues. And it seems to be an issue only after the car warms up.
As 2014s came with a 100K/5 year PT warranty, I just might have it looked at.....

c7 clutch problems
my 2016 z06 shifted funny in 2nd gear from day one, started making funny chatter noise at about 15000 miles, at 19000 miles I found the clutch reservoir totally empty, dealer said they could find no leak and only make the noise once, not enough to diagnose.
sent me home and told me i was lucky they weren't charging me for looking at my car, car is 4.5 years old. when i got home i bled the clutch, found air in line. That gm service tech told me that gm sends them out with very little fluid???? the chatter got better , but at this point i'm wondering if they hurt my car. I know the clutch is past warranty but i think they caused the problem.
PS I also own a 68 corvette with 75000 miles, still has original clutch, I've owned it for 32 years.
Pretty unhappy with gm right now

Much easier than removing some exhaust parts and cover plate to access the blead valve. Typical dealer charge has been reported to be $150.

My 2017 GS M7 34k miles chatters violently in first gear but only after i have been driving all day so maybe after 50 miles or so. Doesn't affect shifting just take off, especially if I am on a hill whole car shakes. Going to try this no throttle take off see if it helps but im wondering if this is the problem https://www.corvetteactioncenter.com...2020-1480.html

if you hadn't used the Ranger Clutch Fluid Repayment every year, try it. If have never had the clutch fluid charged may need the ~$200 dealer flush service method mentioned above.

turns out and it took me awhile, they came with clutch fluid out of the reservoir, they take it out at the factory according to two dealers. its part of dealer prep to put it in. so the line is really long and it took awhile for it to suck in air. it had no leak so the only conclusion was it was empty from the factory. the noise is very seldom now, makes you wonder about future. the sad part is gm didn't care.

Sounds strange! They don't take brake fluid from the Master Brake Cylinder out why clutch fluid? 5 of my 6 Vettes starting with a 1988 have had clutches (only my C8 DCT does not.) None were every empty. Does not sound right that it comes empty from the factory! I did have a case where the cap on one was not put on fully and some fluid did leak out. But never that much.
