This problem is larger and even more concerning than is let on. I have a brand new 2024 Silverado 1500 GAS (not diesel) which has already had to have the transmission valve body.replaced with the same issue. Happened at less than 3500 miles... So the software update to detect it 10,000 miles in advance is clearly inadequate. Worse off yet is GM has yet to recall any GAS models for this issue yet.
