anyone tune out the 2-3 clunk?

[cool05z71]

I have the infamous 2-3 upshift at light throttle driveline clunk in my 05 Z71

With HP Tuners, I have tried various combos of shift duration time, shift speeds, shift pressures, TM on & off.

It is a bit better now, but wondering if anyone has had more success?
Thanks

I have the clunk also, but have not tried to tune it out.

I am not sure.. but may be a transmission reprogramming kit? or shift kit?
