Mine has 71,000 2018 and I’m having the same issue. You are right, GMC knows it too. It’s a big problem affecting a bunch of trucks.They should have to replace these transmissions… they are junk.
I’m interested to see if people that had the transmission replaced have had any more issues? Is it worth it to bite the bullet and put a new ( GM) transmission in my truck? Does it fix the problem?

It’s the same Transmission torque converter problem they have had for years. I have a 2018 low mileage with the same problem. New or rebuilt transmission is the only solution. GMC has let us down
