Does anyone have a good A8
 

Seeing that there are so many GM cars and trucks using the A8, are there any confirmation stories about how good they are?
Here, I will start. I have only great things to say about my 2017 Z51 A8, it's shifts are quick and solid. It cruises well and it seamlessly switches from V8 to V4 and back again when power is required. Using the paddle shifters is fun but the automatic selection has more accurate shifts with no human lag.
It is my impression that the 2017 models have been modified with different TC and are using different fluid. These Mods have remedied the majority of problems related to the TC.

I invite all members to write there good experiences with the A8

Thanks, looking forward to hearing all the good stories.

Mine seems fine but I have only driven 300- 400 mile on it so far.

I have a 2017 Grand Sport with 6k miles on it and my A8 has worked flawlessly for me. I drive 100% in manual mode and it has never shifted without me telling it to.

My ‘17 A8 has worked flawlessly over the 2,000 miles I have driven it.

Thousands of good A8s out there, so far mine included. .

Got my '17 Z06 in April and now have around 9,500 miles on it. Not even one tiny indication of a problem, so far.

My 2015 Z06 had the A8. My 2016 Z06 has the A8. I just ordered a 2018 Z06 with the A8. I have never had any problem with this transmission.

13K no problem. V4/V8 is almost imperceptible. But little by little I really came to prefer M mode, and now that's all I use. I tend to prefer a slightly higher RPM than Auto, and like to downshift for the corners.

Personally, I think some of the discourse comes down to what is considered a problem--example: I have had a lot of Manuals over the years, and with a cold transmission the 1-2 shift can be a bitch. But with a M that's OK, with the A it's a glitch? (My A8 shifts a little different when cold than warm, which I expect, but no delayed engagement)

Got over 5100 Miles since first of July.She does hit 2nd not real hard or soft either in Manual Mod.Simply regulate the throttle a little..Fixed
Mostly shift back and forth from M to A.Depending on the road if it's Playtime or not.Man,This car can PLAY

My 2017 GS A8 has performed flawlessly so far.
Across the GM brand there must be a couple hundred thousand vehicles
out there where A8s perform without issues while there's probably only been a couple
hundred +/- failures reported on this forum.

Did all 2017s receive the improved TC and fluid or were the improvements implemented at a certain build date during the year?
Anyone know?

What most people don't realize is there's thousands of A8's out there and only about 1% have had problems. It's just we all hope that there were zero percent but the way some complain on this forum you'd think every one was defective. They're not.

According to the Poll on this forum, most of the A8 problems were with the 2015's and 2016's.

Bought mine on Labor Day, and so far so good. Still under 1K miles though.

2016 Stingray with 3400 miles, so far so good !

2015 over 10,000 miles perfect. Original owner. Picked up 9/2014.

It seems all the A8's are destined to grenade sooner or later, buy the M7.

An incorrect and ridiculous assumption.

Churn and burn
 

I have to ask - why do you dump cars so fast? I wouldn't expect any trans problems with only a year or so of use..

2017 Z - First 2k miles car would intermittently jerk & bang, then an AFM/DOD delete (plugs) during engine mods/tune. 5k now & its like driving a different car - smooth as silk. I still don't know why GM decided AFM was a good idea on these cars & that shit system is whats shelling these A8s.

As the subject matter identifies. We are looking for positive feelings with the A8, I will disregard yours as a personal unscientific conclusion based on your desire to divert from the subject. There are an equal amount of clutch, throw out bearing and stiff shifting problems which we all should not bring up. Sooner or later you will experience this grenade as well.
