I bought my C7 used with 18,500 miles. Had to drive it home about 135 miles and once I got on I70 coming from St Louis I knew right off that it needed the GM flush. I had a few months till the warranty was up so I took it in to my local dealer and they flushed it and no problems after that. Had my 17 Sierra flushed a few years back cause it was shuttering also, flush fixed it. My 16 Camaro that I sold had 250 passes down the track and 13500 miles and it never shuddered and is still in the car after all those passes and miles plus the fluid has never been changed. If it don't shudder don't flush it, just leave it alone.

Is your C7 demonstrating any of the other systems of the A8 shudder except the fluctuating RPMs? (1) - Surging and Lugging - Your car can't seem to maintain constant speed.
(2) - Shuddering - Feels like you are running over a rough road when you are on a smooth road. Comes and goes without warning.
(3) - Vehicle Lurches
(4) - Slow to go into gears including reverse.
(5) - Gears don't shift easy.
(6) - Strange Noises - Clicking or revving.
(7) - Gears Slipping - Loss of acceleration.
(8) - Overheating.
(9) – RPMs jumping up and down slightly at constant highway speed.

I'm getting ready to jump in the pool. I tried searching and get many different random results (of course) so if there is a thread that completely explains my questions, feel free to point me to it.
If not, may I ask on which cars this problem occurs and whether or not it happens (eventually ?) with ALL C7s with the A8 tranny ?
Otherwise, for the newbies (or which I am one), can you explain what this triple flush is, whether or not the dealer is required to do it under warranty and if not, what it would cost to someone to have done ?
Does it happen to ALL C7 A8s eventually ? 1 out of 3 ? 1 out of 10 ? How often ?
And thanks for listing those symptoms !!!
TIA

"Symptoms", yes ?

The triple flush now fixes the issue in most all cases and is covered under your 60/60 drivetrain warranty.

I expect there may be some who are oblivious to having A8 shudder, but doubt there's many. In regard to your doctors/lawyers/indian chiefs crack, are you implying they aren't capable of knowing when they have something wrong with their vehicle?

AND, just for the reason you are having. When I go to inspect a used Corvette and find something wrong with it, or it's not as described in the seller's listing (which happens more often than not) I just simply walk away.
Something tells me it's not that simple when purchasing from Carvana, Vroom etc. after they have already prepared the vehicle, processed the sale and delivered it to you. I might be wrong.

Maybe you can contact a dealer and see if it had the flush done already? I can’t speak for the A8 as I have the A6 but when I first got my car I wondered if something was wrong with the transmission. It was just the car going back and forth into V4 mode. A range afm device solved that problem.
