2011 GMC 1500 LTZ truck. E38 with TCM in Pan

As I said earlier My trans guy said since it was only at the beginning and not every time it shifted from 1 to 2 to 3 etc, and only after a start up it had to be programming. not the internals of the trans. he told me to take to GM and have it re flashed. has anyone had to do this since the truck is not a 2011 anymore.
Can I license another file and upload to the PCM from like from another VIN of the same year and model truck??? or a Camaro etc?
