A8 Shutter problems built after March 2017

Lonny · 07-18-2018, 12:47 PM

Since AL announced that GM changed the tranny fluid for all A8's built after March 2017, I was curious if anyone has experienced the shutter issue with their A8 if your build date is after March 2017. My build date is June 2017 and I have had no issues. If you don't know when your build date is you can request a build sheet from the dealership you purchased your car from.
Thanks

mine was built May of 17. I've had the triple flush performed twice, with the new fluid. I'm currently on a new torque converter because the issue wasn't resolved.

I have seen a post of a 2018 having this issue May have been in ask al?

2016 - 2018 MYs still have the A8 issues, tons of them still.

It seems hit or miss- I ran into a guy dropping off his 2017 C7 for maintenance at the dealership this morning and we started talking about the shudder issue in detail. He said his car is experiencing no such issues.

Going in for my new TC from the dealership.This issue was and at that time they offered the triple flush and same ole story worked for a while then back to the same shuddering in overdrive gears 7,8.
The service manager said they had fluid additive issues?

Mine is back in for the shudder. Originated at 1400 miles, triple flush was performed.

Dropped off last week at 10k miles, tech confirmed shudder is back.

I should know within the next few days what their plan is, I wish it were an entirely new transmission just to have peace of mind that contaminated fluid will not create more serious problems at a later time, but this is GM, I don't see that happening at all.

I have a thread on this too and my car has only 6K miles on it and Service confirmed to me yesterday that I need a new torque converter. There are 4 ahead of me with the same issue, so it's going to be a week and half to get my car back.

Mines a 2018MY and mine has a noticeable vibration when going from V4 to V8 mode. It feels like the transmission is slipping A LOT. It will slip for a good 1-1.5 secs, which is hell of a long time if your trying to pass somebody, feels like I got to wait for my damn turbo to spool up or something, feels bad man.

Added range device to eliminate AFM all together. It helped a lot, shudder is 95% gone. I can still feel it ever so slightly when cruising at a constant speed and slightly pushing the throttle in to accelerate. Happens for maybe .3 seconds. Much easier to live with and doesn't seem to be getting worse.

@14k miles.

my 17 has 11k on it now and have seen 0 trans issues this far.

I took my 2017 SS2 A8 in at 8000 miles for shudder and they did a trans flush. 4500 miles later and its beginning to come back. Im going to wait until it gets more noticeable before I take it back in. Hope they replace the TC this time.
