I had the same transmission shuddering issue in my '18 Vette, the transmission fluid was exchanged for the reformulated fluid back in '20 under the warranty, now 4 yrs later, with only 25k mi on the car, the shuddering has returned, so looks like the flush is not a permanent fix. This is an ongoing issue with several other GM models as well. There is currently a class action lawsuit against GM for this. GM knew their transmissions were faulty, but went ahead and put them in their vehicles anyway. They obviously don't care about their customers, and it's hard to trust the dealerships too. I bet the customers are going to end up with the short end of the stick on this issue. By the way, that fluid flush should only take a few hrs to do.
The rattle is most likely the belt tensioner. I noticed the rattle mostly happens at cruising speeds when the engine switches to 4 cylinder mode. The belt tensioners are also known to be defective. I replaced mine and that fixed the issue.
My 16 Cadillac cts has that transmission flutter issue as well. I’ve always been told not to flush the trans fluid. But it seems like it fixed the issue for you.
It did! In the video I showed that article I believe how in 2019 they came out with a new transmission fluid I would mine runs an shifts a lot better now
Yo bro I love the videos I be posting myself I just wanted to ask what you use to refit your videos and thumbnails keep up the good work bro congrats on 2k

I really appreciate this bc I thought it was something else, how much it cost to replace that?
It’s a recall on all LT1 transmissions. GM put the wrong transmission fluid, my local dealership did it for free😳 And it only took them 3 hours.
I knew I got robbed like it’s not my fault they put the wrong stuff! I’m jus happy it’s fixed it runs so much better now

All corvette and zo6 from 2015 to 2016 have the jerking problem. I believe GM need to do recall for this year. My 2016 zo6 have the same problem.
They made you pay for the flush? I thought that was covered under a Service Bulletin through Chevy
Yes! I might look into that because it was $825!
Bro I just bought a 2017 zo6 with 60k miles, and I notice the shudder at low rpm, dealership charging 1200 for the flush
