Update. 1050 miles now and trans seems to have learned quite well. I am pleased to report that the previous problems are very few now. The PIP5437B seems to have resolved the problems. The truck, with the 6.2 and the 8sp is a beast.....very happy.

Not me. 2017 here. 6.2/8 Sp. Same issues. LOVE the truck and the 6.2, transmission is possessed at low speeds, turning, coming to a stop etc. Clunks, Harsh Downshifting, Surging. No problems when your on the gas though, impressive, smooth as silk. Just had TCM update from the PIP5437B bulletin applied at 600 miles. Not sure it did much. Ill give it short to while to "re-learn".
