this morning when I went to drive my truck I got a service stabilitrak notice, followed by a clunk, check engine light, and the dash not knowing what gear I was in. I scanned the code, which was U0101 lost communication with TCM.
I spent some time researching but can't seem to find anyone else with this issue. The truck is a 2014 Silverado 1500 RCSB 4WD 5.3/6L80e. To my knowledge the TCM is now inside the transmission, but not 100% sure. Only 38k miles so I'm unsure what/why/how this happened. Everything has been fine until this morning.
Hoping to get some info here before towing to the dealership.
