2007 Yukon Denali AWD, 402" LQ9 LSA Blower 9.1" lower/2.5" upper, NW 102mm TB, Built 6L80 except Billet input and Circle D 265mm Triple Disc... 850hp or so
So I don't want to do WOT lockup shift and break my input shaft but I'm see 600-1,200rpm of TCC slip under most WOT conditions... I thought these things dont like to slip? Should I lock it by MPH and unlock before shift? Whats the best method for this? Attached are my tune and two logs with some light WOT pulls. Also attached my MAIN config file, renamed as a XML, change back to .CFG and backup your old one. That will import ALL channel/gauge configs... Thanks!
