A8 factory reprogram

I was at the dealer getting the rough track calibration and the power steering ventilation kit installed on my 15 Z06/Z07 and the technician told me that if I say that my car shifts "harshly" there is a service bulletin on that car where they will reflash the transmission computer and then "teach" the computer how to shift more smoothly... It made a big difference... No hesitation and no uncertainty in the lower gears at lower speeds....AND it was covered by the warranty... Bulletin came out in Aug 2015 and my car was built in March 2015 From the paperwork it seems they charged GM about $1500 for the process....

If you can find the TSB # that would help me too. Some dealers are ignorant and say ignorant things and you never get it fixed.

I'm sorry but I cannot find these TSBs. Can you help me find the text?

I'd also be interested. Last time I was at the Dealer, they told me my transmission was fine and that they would not perform it for me. Thanks in advance.

Me too. I think the TSB Information would help my case a lot. I would like to be able to read it.

My 16Z was built 6-22-15. I brought it to the dealer last week for it's second oil change. The transmission was reprogrammed along with pdk autostart and seats (temp). There wasn't a tsb # on the invoice so no help here.
