8L90 tune on 2015 Denali XL
I have been reading but not found any definite answer to this and hope somone can help. This is for my wife's 2015 Yukon XL Denali 6.2/8L90. We love this truck. Only issue is the 1-2 shift when the truck is cold. I raised the shift speed to 11mph and it seems to have helped a little but it is still uncomfortable. Can someone shed some light on what else I should do to help tune this transmission to make it smoother when cold? Any known tunes out there that someone might share?
Thanks in advance!

Without a log and current tune file it's going to be hard able to help, ad a log file and tune file for everyone to look at for a better response.
