Did you adjust the gears in the tune for it ? You can just also adjust them using the vcm scanner

adjusted in both ecm and bcm although bcm did throw an error code after update.

Need to see the tune and log to help you. Otherwise it is a bunch of guesses.

I remember having a similar issue with my car, and I disabled Tipin management. Solved the problem, but not sure if that is the correct way to fix issue.
