Code "U0076 - Network" and pending code "U137D - Network". Anybody have any clues? I cleared them once already and they came back. Quick google search returns nothing, which I've never encountered with a fault code in the past.

DTC U0076 is Control Module Communication Powertrain Sensor CAN Bus Off.U137D is Gear Shift Control Module Received Invalid Data from Engine Control Module and is set by K212 Gear Shift Control Module & K20 Engine Control Module.
No bulletins that I see. Looks like it could be a communication data line fault or an internal module fault.

Again, I had a problem (forgot details) and dealer had to R&R the shift. Good thing under warranty, apx $1000 Part (maybe P&L) from what I remember.
I did a search on U0076 - Network and got a number of hits. I did not include the quote marks. Did not use Google, just the "search the web" field in Windows 10.
update: The dealer still has the car. The tech found a plug that wasn't in 100%. If this doesn't solve it, they have no idea what it is yet. They talked about the possibility of a wiring harness. They also talked about flying someone in from GM.

Hope it works out to just be the plug, the wiring harness is kind of a last efforts approach to an electrical gremlin but many times they end up finding a frayed wire or something not grounded properly etc. while in the process.
Check Engine Light!
