could not find the actual document without paying for it but the campaign is for "customer satisfaction" and ends next month so
my advice is to boogey over to the dealer and see if they will do anything or not, probably a gamble depending on your relationship with the dealer.
the TC is the known weak spot.

I found this, but it says silverado/sierra:

I did not know anything about this, but coincidentally recently took my 2019 5.3 in for service and complained about occasional rough downshifting when coming to a stop. When I picked it up, the service advisor said, “We flashed the TCM—no charge.”

I haven’t experienced any rough downshifting since, but maybe haven’t driven that much yet. The shifting has changed since the update. It feels more “deliberate,” sort of more like the 6 speed Allison in my 3500 Duramax.
