Have a 2016 GMC Sierra 1500 and my transmission failed at 152,000 miles but had fluid and filter changed numerous times, transmission updates and adjustments prior to its failure. Installed a GM remanufactured transmission through the dealership and transmission failed after 600 miles. Dealership had to replace the transmission valve body and I am currently at 175,000 miles. Have my doubts it will last the 3 year 100,000 mile warranty!
