A8 shudder/ fluid flush
Brought my new to me, SS to the local dealer for the dreaded A8 transmission shudder. The car drives fine at highway speed, but shudders around 20-35 mph. I printed the service bulletin (which I know they love to see), and spoke with the service manager. She said it may be covered under my certified used car warranty, but wasn't sure. Which means it's not covered. Said it would be $695 for the fluid flush if I had to pay. Got a call at the end of the day saying they didn't do the flush because 3 of my wheels are bent. I know anything is possible, but how could I have 3 bent rims and the car drive perfectly at 80 mph? They want $160/ wheel to straighten, then they will diagnose the transmission. Sound reasonable? I took the car home untouched.

Not reasonable at all. Why did they even look at the wheels when you told them about the shudder, makes no sense. Find another dealer or independent mechanic. $600 plus for a fluid flush is BS!
I had the shudder in my 2015 C7. It was so bad they had to swap out the torque converter as well as replace fluid(s). Lucky for me it was covered under the original warranty. Can't imagine that finalized bill. Good luck. |

Sounds like they are trying to royally screw you over. I'd take it to another dealer.

If wheels were bent, especially 3 of the 4, you'd clearly feel vibration at various speeds, ie the car may feel fine at 80 mph but then vibrate at 45 or 50 mph. Guess what they're trying to tell (sell) you is that what you thought was shudder is shudder plus problematic wheels.
This isn't impossible, assuming that you aren't 100% sure what the symptoms of trans shudder are, but I would definitely have these claims verified by another shop or dealership, without sharing this info beforehand of course.

FWIW, my 2016 2SS shudder was only noticeable on the highway as it would switch between V4 and V8 mode.

Do you have the service write-up? How did they determine wheels were "bent?" Visual inspection, spin balance???
A small nick in a wheel does not mean it's bent. And what exactly is this straightening process they are proposing? |

The A8 shudder ain't no joke. Every GM I've had with an 8 speed has had it at one point or another

It also always occurs at the same speeds relative from one person to the next. In my case on my 2016 it happened at 50mph and 70mph.

Why don't you think the wheels could be bent? Just cause it's shiny doesn't mean the previous owner knew how to drive. I would be looking to the selling dealer for some help if you bought it certified depending on how long you have had it in your possession.

After a little over a week, I had a new torque converter and fluids (transmission and differential) changed. The car only had about 500 miles or so. At least it was all covered by warranty. Never had another problem and eventually traded it in. What sucks is GM knows its an issue and has been from the beginning and should have a recall or extended coverage on it. |

Doesn't surprise me that you would get a quote like that on Long Island. I was going to have it done in CT by my dealer as a preventive measure on my 2017 2LT and the quote was $450. I then said I thought I felt some shuddering around 30 to 40mph and he did it for free under warranty.

Should be easy to confirm or debunk if your wheels are bent. Take the car to a Tire Discounters or such and ask for them to re-balance the wheels and check if they are bent. Won't cost much and a re-balance of the tires/wheels is never a bad idea.
If not problems with the wheels, definitely find another dealership for the trans flush. Or if you are able, do the flush yourself. |
