'15-'18 Owners Get your A8 Flushed!
I wanted to share a quick update for anyone on the fence about the A8 Triple Flush.
I have a 2016 C7 with 43k miles and no record of the service being performed by the previous owner. I decided to have my local dealer handle it last week, and I can tell you with 100% honesty: the difference is absolutely night and day with the new fluid and filter. The shift quality and overall smoothness are significantly improved.
If you haven’t had the TSB triple flush completed yet, I highly recommend getting it done regardless of your mileage. At this point, the factory fluid in these early cars is nearly 8 to 10 years old. It’s well worth the peace of mind and the drivability gains. Even if you have a 2014 with the A6, I am sure you can benefit from a fluid flush.

AND, if you purchased the car used, you don't have any idea what someone put in your car. I have the 2014 A6 and changed all the fluids. Just check the latest GM updates for all the fluids, things have changed since your manual was printed.

'15-'18 Owners get your A8 flushed
I am new to the C7 forum but not not new to the Corvetteforum. I am here from the C6 Z06 forum. I bought a 2017 Grand Sport 2LT with 5000 miles on it. I was experiencing tachometer variations while driving in the 40-80mph range. I had the triple flush done at a local dealership and it totally changed the way the car drives. It is a night and day difference. I have put about 2000 miles on the car since having the triple flush done and everything seems to be working the way it was designed.

Haven’t had the transmission fluid flushed on my 2014. Guess I need to consider it even with just 10K miles on it.

Vetteman - With a 2014, A6, you do not need to worry about the A8's shudder and the triple flush, but, given the age of your Vette, suggest you have the trans flushed (in fact, all fluids should be flushed due to age instead of just mileage unless you already did it). Good luck.

Providing not too many miles (IIRC Chev recommends every 50K), a flush probably a good move.
On a related topic, we own a CTS w/ what I believe either A8 or very similar to C7.
We'd awful shuddering, took it to our long standing wrench.
Good guy w/ >30 yrs experience w/ all vehicles.
Asked for a flush.
He cautioned against FF due to our high miles, >100K
Advised full flush MAY lossen debris trapped in every nook and cranny.
Crap could clog tiny passages causing real headaches down the road.
Instead he drained every drop of fluid he could, refilled w/ 'new' fluid as recommended by GM for A8.
Has been nearly flawless ever since.
High miles the deciding factor behind his strategy, FWIW.
YMMV

It's possible that the car was assembled after the changeover date but the tranny was built a few days before that and has has the old ugly fluid.

IIRC, it was the "hand me down" stuff that was the issue. Had they used the right stuff to begin with, maybe there would be less problems? That said, if I knew then what I knew then what I know now, well, I'd be rich beyond the dreams of avarice. Like most things, you know now what you should have done and when you started, there were tons of issues that got ironed out over time.

They might have been by 2014 but were they when the first came out? According to THIS, there were some issues.
However as stated mine worked well from the get-go.
Lucky?
A8 following the 'partial' fluid change on our CTS, has performed well.
No shudddering, a decent xmission w/ buttery smooth shifts.
Still took GM fo' evah to come up w/ improved fluid solution vs replacing entire unit those first few years.
Torqued-off a good many owners, rightfully so IMO.
An expensive lesson for the general, somewhat akin to C8's DCT problems.

No doubt A6 had issues following introduction.
