08 Z51 A6 shifting issues

Just got back from Black Hills Corvette Classic (BHCC), my slow shifting A6 paddle shift is wearing me out! The transmission shifts slow and 'hunts' for gears all the time, it can't seem to determine whether to up shift or down shift while engine revs then engages late and hard. I met a Chevrolet dealer from NE at the BHCC , he tells me GM has an "under the radar" fix for this problem and I should be able to find a TSB for it on line (not sure how can it be "under the radar" is TSB is posted on line, have not found TSB yet). Does anyone have this issue and have you been able to fix it? Coupe has 15000 miles on it and still under warranty. Running some track events next month and need a tranny that works as advertised.

Thanks for the info on the link, I will continue to drill down for some answers, I may end up going with a tuner program but want to explore everything possible through GM so I don't void the warranty.

I see by your profile that your corvette is arctic white (so is mine, 4th white one for me). Real Corvettes are white!

I think the TSB you are asking about is in this thread, post #27. You can read the discussions up to it to see similarities to your situation:

And here's a thread where a member posted his observations after having it done:

Good luck.
