Default Check Eng Codes P00FF, P0700, U0401

The CEL on my 2024 Z06 with 4,000 miles has been comimng on now and then and goes back off before I can check the codes while the light is still on. Today it came on and I had a chace to check it. Codes were P00FF (history), P0700 (current), U0401(History). Anyone have the same codes issue? If so, just wondering what the outcome was? I do have an appointment at the dealership for next week but now the light went back off. They told me not to bring it for the appointment if the light isn't on. So, I'm trying to get an idea, figuring someone else had the same codes.

I had P0700 show up at the track. Cleared it and it hasn't come back. The U0401 is a communication fault between systems. They could be related. I'm guessing a communication issue between modules that's causing the TCM fault. I don't think it's a serious issue mechanically. Hope they can isolate where the issue resides. Let us know what the outcome is.
