Lost communication with TCM
codes: U0101 and U0073
Truck is stuck in 5th gear, service advance trac message, and my edge cts 3 is unable to pull the PIDs from the vehicle. Checked the 10 amp fuse on the drivers side of the engine bay and it’s fine, also no notable wiring issues that I’ve seen. Tried unplugging both batteries and letting truck sit, also tried unplugging TCM. Just cranked up the truck the other day and started happening. Any suggestions would be greatly appreciated
