A8 shudder issues?

[wkndracr2]

I might relate an experience I had with first fluid change after initial track experience. I was unfortunate in picking a dealership two years ago that used an old, out of date fluid. The vehicle then developed the shudder. Now, after two more flushes/changes it may be getting better. Hopefully by now every dealership has the latest fluid and techs that understand our ZR1's require specific steps for successful fluid change.
