I've had mine back since getting Bulletin 18-NA-355 performed. My invoice mentions: "torque converter shudder with pico scope 39.4 hz 66 mph 1528 rpmin mode a and shudder not present in mode b". I've put just over 100 miles on it since then and it really does feel like a whole new car now. Shudder is gone and the shifts feel completely different than they did before. Hoping things stay this way for many more miles.

Good to hear, let's all hope this lasts, no more issues.

GM was supposed to announce a fix for the A8 8LE90 in the first quarter of 2019. Well the 1st quarter ends in 2 weeks and I haven't heard a peep. Has anyone heard anything or have they shutdown all attempts to fix in the wake of the pending class action?

Do they take your car out for a drive with a measuring device attached some part of your car or do they get this info from plugging into your ECU port and pulling codes? |

This is what happens when GM screws over their customers for
5 years straight by refusing to admit and fix their f'ed up crappyA8: https://jalopnik.com/the-ford-mustan...m_campaign=top yeah I know, I'm not nearly as well-versed as this happy owner: |

It measures the vibrations from the TC. The only way they will do this new flush, is to have vibrations show up on the picoscope, otherwise they will not do it.

Yeah, they put 26 miles on the car while they had it - assume some was with the pico scope and some was after each drain/fill until the flush was complete. I'm mostly interested in what "mode b" was that didn't exhibit the shudder.

So the dealer drives the car 5 miles and can't measure a vibration because
they don't drive the car in a manner that would allow it to happen. Then they proclaim the car is normal. Just Brilliant. BTW: I dealer I took the car to had never heard of shudder and I had to show them the bulletin on my laptop. After that they were skeptical that it was a real issue and said no one has ever brought a car to them to diagnose something like this. |

Mine had about 40 miles on it when done. They had to drive it and diagnose it first with the Pico scope. Then after the fluid exchange.

I'm sure they changed the fluid, it had the horrible first few shifts when I got it a lot of us have had, and vibration was gone after.

The hilarious part, is that GM hasn't changed their styling, like it matters. Many people say this, implying that's why it's third in the pony car race. To these people, I have one simple reply. LOOK AT THE CHALLENGER!
