Any updates on the new fluid? How many miles since? I'm trying to follow this thread to see if this is really a fix or just something to get the cars past the warranty period. I have an LS3 A6 now, but want the v3 only if the new fluid lasts at least a significant time before needing exchanged.I had my tranny flush accomplished per the latest TSB, V run great no more vibration/shutter. Wanted to confirm tranny fluid level was correct, that when I leaned after looking for 10 mins for a tranny dip stick that we don't have one!! Now that's first for all my GM vehicles ever owned! So you have to go to dealership for any tranny fluid change in the future, no more do it yourself fluid/filter preventive maintenance. Makes you go HUM!!!!!
