The 2-3 shift "clunk"

The 2-3 shift "clunk"
I thought I would post this in the tuning section. I have a freshly built performance A4 transmission in my Camaro. This transmission has the infamous 2-3 shift clunk at light throttle only. This is inherent from the performance parts installed. I know why its doing it, the 2-4 band is releasing sooner than the 3-4 clutches apply which causes the trans to freewheel for a split second then bang into 3rd gear. The downshift from 3-2 is the same.
What I am wondering is if there is something I can do to the transmission tune to minimize this condition. Line pressure, shift time, etc. I have HP tuners.
If anyone has any experience with this I would greatly appreciate the help!
thanks
