After reading some posts on here and the Corvette Forum I decided to install the Range AFM disabler.

The device plugs into the OBDII port and prevents the A8 from going in and out of 4 cyc mode. I thought I was imagining that the transmission shifts better with the Range unit. I purchased it directly from Range to be sure I got the latest software version. My 1-2 shift is definitely better with the unit and the transmission is smoother and more responsive. I had the shutter and flush performed and just want to try and protect the Torque Converter as much as possible.
We should not have to deal with this crap but it is what it is.
