Transmission Fluid
I have a 2019 GS 3LT with 4900 miles. I have recently noticed some mid speed (60-70 mph) shuddering experience occuring. I have new Michelin tires on the vehicle which I recently inspected to be OK. Has anybody experienced this problem. I was wondering if it is a by-product of bad tranny fluid.
Thanks,

Try your luck and find a dealer with one or two Corvette certified techs. Talk to them about the triple flush. After that, make an appointment with the appointment clerk aka Service Advisor.

You need to check the build date of the TRANSMISSION. (not the car build date).
There is a label on the trans that has the date.
If the trans was built after 2-01-19 then it has the new Mobil 1 Blue ATF.
If built before 2-01-19 you need to change the ATF fluid to the new Mobil 1 Blue label.

Its called 'BLUE' due to the fact that Mobil 1's bottle has a blue label on it.
The fluid is not blue in color.
I had all 3 types of fluid in my 17.
Original, don't know the color of the bottle.
Mobil 1 Black label bottle.
And now Mobil 1 Blue label bottle.

You say u just installed new tires that you inspected ....... don't discount the fact that tires, wheels or anything that rotates can mimic the shudder, I too had new tires put on my car, jumped on the highway to run it up to speed and instantly had what felt like shudder, even though I have V4 tuned out. it took to more tries at Road Force balancing before Discount got it right, the manager stated that there is a tolerance that they use but on the 2nd time they just kept at it till they got a " Bullseye" balance
If I did not just have the tires put on, I would have sworn that I had the shudder
