I'm past the point of being pissed, it's just whatever at this point, and honestly its why the stack of mods for my car have been sitting on a shelf, because I knew this would come back after reading what everyone else has said, and I want any and all problems handled prior to bolting on a single thing.

Torque Converter.

Anyone know what range of VINs they are talking about?

If you mean GM Customer Service, They Have No Teeth At All! They provided me with no assistance what so ever. It only added another level of complexity in dealing with them as well as the dealership. If i could trade the car in and not loose my A** i would do it in a heart beat. I love the car, just not all the problems that come with it: Rear Diff Groan, Transmission Shudder, and all the little things that keep failing (Computer screen failing, pasanger side door not opening, drivers side door light failing, etc.). Each problem is multiple trips to the dealership. If GM would step up and take care of there coustomer i would not mind, but it seems they are turning their backs on us with this transmission and read diff thing.

Mine was built on February 17 2017. And I was one of them.

Don't let them do that. You should wait and have them replace the fluid also.

Mine got the flush at 10K and all was well untill the shudder came back at 15K. Torque converter was replaced along with the filter and fluid and the car is perfect. The service manager told me that the latest from GM is to go straight to the converter and forego the flush even if the flush has not been done.

Ill have fluid too.. but form my understanding the issue is the redesign of the plate and the additive. Thanks

Well, that’s interesting. Had a flush (only) 2 weeks ago....

The original fluid for the A8 was Dexron HP. This was not a sythetic fluid. It was determined that the friction modifiers in this fluid were incorrect for the application which is why initially the triple flush did not work, even with a new converter. Same fluid, same problem.
Now the required fluid is Mobil1 LV. It masks the issue temporarily but if you had the shudder, the damage had already been done (burnished TC clutch plates).
In the meantime the TC has also been redesigned to alleviate future issues.
I only recently left a Chevy dealer where I worked as a parts-to-service liason and can assure you that the TC has a new part number as well as revised TCM programming. I can also assure you that Mobil1 LV is NOT scarce, we kept cases of it in stock, find another dealer.

Very concise information, particularly about the revised converter and program. Thank you

Thank you for that info. I am headed to a different dealer this coming Monday. Perhaps this will help. Would love to get this behind me and enjoy the car.

VelvetHammer is correct. Yes it was the fluid not the TCs (for the most part), and yes getting the new fluid is critical. But once damage is done to the TC (extended shuttering) you need to replace both.

Folks you need to go read the ASK AL post on this for all the details. Print it out and bring it with you to the dealer if you get a runaround ... and have them look up the TSBs.

while I'm not in the position to disagree with AL, I do. He mentions that after March, *every* car came with the new fluid, filled from the factory.

My car was built in may, months after the cutoff. Not only did I get the shudder, but 2 triple flushes with the new fluid didn't cure it, requiring a new torque converter.
