6L80 Camaro Trans issues?

[Badassbird]

Can someone please take a look at this tune and at the log and tell me if they have seen this issue. Thye mods on this particular car are 233/239 cam, LS7 lifters,Procharger D1 on 9lbs,Longtube Headers,SW Quiet Cat-Back and FTI Converter. The car makes 615rwhp and 509 ft.lbs. I have done upwards of 60 of these cars and have not seen this issue. At or near WOT it will surge or possibly hunt for gear. Maybe even clutch locking and unlocking. Please check it out. I have made many changes and none have made a difference.
