2019 sierra slt 5.3l 8spd , so last week going to work my truck went into limp mode and just stopped moving after a couple miles, had to get it towed home and got these codes ( u0101, u0100, p2535) I assumed it was the tcm so I went and bought one online and had it programmed to my vin, I just installed it today with a new battery and the truck doesn’t even start anymore just the dashboard and radio turns also I got the same codes, has anybody had this problem ?
