Do you mean you had two triple flushes with the magic blue label fluid? Or one with the previous gen black label and now you need a second?

So many fluid changes and no results. I think GM knows its not the fluid but a defective transmission. Their solution is to keep changing the fluid until everyone goes away. But good luck to you though maybe you will have success.

My Z06 is a 7M, but I have a 2015 GMC Sierra with a 6.2 and 8M and it had the same type shudder that many Corvette owners have reported.
At about 3k miles they did the transmission reprogram and it didn't make a difference, so a week or so later they did the triple flush and I'm now at 43k miles and have had no more problems with shudder.

After 2nd magic blue flush, shudder almost totally gone. It may take a couple hundred miles to take total effect. Transmission is like butter!
