Just got my 2021 Chevy 2500HD out of the dealership for this problem. Snapped the transmission output shaft off. Right where GM welded the speed sensor ring to output shaft. Service advisor has seen several of these come in, breaks right at the weld. Fortunately it was covered under extended warranty as the replacement transmission, labor, new cooler lines, and a couple minor other things was just shy of $9k repair bill.
