They flushed mine, that didn't fix it. Then, they replaced the TC. In one of those steps, they also updated the tune on the transmission. It's been a year since they did the work. So, I don't remember if they flushed & tuned or flushed, then replaced the TC and tuned.

I traded it back in February. I've been watching these Shudder threads to see if I should kick myself for trading.

Don't kick yourself. You made the right decision. That 8A never performed correctly even when it didn't shudder. It is inherently flawed. Why would it even need all these flushes in the first place? Their previous automatics didn't, nor do other manufacturers' automatics. It's all just GM B.S.

In my scat, if my car is in 8th on the highway cruising, it will immediately drop to 7th or even 6th if I roll on the gas almost at all. Then its in a much better rpm range. The camaros seems to stay in their top gear longer than they should. Im wondering if a TCM tune would help cure this. You know get it to drop gears earlier if you roll on the gas vs letting you stay in 8th and lug the engine while trying to lightly accelerate.

100% agree with your observations. If you drive in manual mode with the paddles or stick you can keep the car from lugging and avoid any shuddering.

Just got mine back today. New revised torque converter, along with new fluid and flush procedure. Honestly it feels better than the day I bought it. No shudder at all, but even more interesting is that the trans behaves a little differently. Hard to describe, but it just feels better and more correct like a normal trans should IMO. Hopefully this completely fixes it. Anyone know what is different about this revised torque converter? Service advisor couldn't really tell me

I hope they fix the A8's. I just had little faith that another fluid change was going to do the trick.

Got mine back from the dealership a few days ago, they flushed it and it seems good to go. Crossing fingers, haha

Drive any rear drive vehicle with the German ZF 8 speed automatic and you will understand how poor the GM 8A was from the beginning, even before the problems began. It is simply a crappy transmission. I seriously doubt that even if they start replacing torque converters again, which they did before and didn't solve the problem by their own admission, or whatever, that the 8A will NEVER perform as a quality transmission. And GM has yet to prove me wrong. Dumped my 2016, SS2, $42,000 Camaro in April and never looked back or regretted it.

I loved my 2017 SS, and I thought the transmission was great. It would sometimes jerk when coming to a stop, and it had a lazy engagement of 4th to 5th, but totally acceptable behavior and the car was an absolute blast. The shudder occurred in a place I rarely drive in and I only began to notice while driving my wife using cruise control and making her comfortable (11-1500rpm slight load @50mph).

But Chevy approved the buy back (which my dealer had suggested) and gave me a full refund, even after the fluid flush which was done in February that seemed to fix it - transmission was working great!

Over 2 years, 6 sets of tires, and 42,000 miles on the car! And they considered my use to stop at 4600 miles so I got a substantial refund.

With my resources restored, I shopped all over again for a car - drove Mustang GT, Charger, Challenger, considered a more family oriented vehicle. But apparently I’m still stuck on the Camaro - nothing else compares, nothing gives me the same feeling, not Porsche, nor BMW, nor Mercedes, nothing I’ve driven, and there have been many more that I’ve tested and compared.

Although apprehensive about comfort, I ended up with a 2019 1LE. I have gone 2500 miles in less than 3 weeks and I have absolutely no regrets. This car amazes me every day. I love the stick, the suspension, the seats. Thank you GM!!!

Awesome outcome!! Congrats!

I have a file with GM for my car and they have said they aim to satisfy me. My 82 Z28 was a dog and I had all kind of issues and contacted GM and they sent reps here to Indy and they got my car taken care of.

I’ve had the triple flush, retune and damn my car is running strong as hell! I’ve got about 2K on it now and I’m happy thus far. Keeping fingers crossed....

Taking mine in on Monday for the power steering TSB and the A8 shudder.

Had the Power Steering TSB done as well. Was there at 8a and out by 9:45.

Cool. I am dropping it off so they can work on it. I hope they can do both in one day but I am not counting on it.
