Grettings,
Lately I have been noticing some slipping in the 1-2 shift when the car is under load and above 4500rpm. Most noted at a WOT 1-2 shift.
Can someone take a look at the attached file to make sure its not my tune causing the slipping or if I'm over looking something?
There was a post about the 04+ Grand Prix GTP transmissions as they react differently to line pressure vs the 97-03 model years.

Also, what are the best parameters to look scan for then trying to diagnose this problem?
I'm running Dex VI and its at the proper level.
Thanks!!
Joe
