Just for fun, I scanned my brand new Tahoe and these codes came up. They seem to have something to do with the transmission, and they came right back after clearing. Anybudy have any ideas? No CEL and drives fine, but I did play with the + and - to manually shift it.

Thanks, I saw those and can't really make sense of them. I am actually suspecting that my code reader may be creating false error messages. The car runs and shifts fine, with no CEL. Not a whole lot on the web about these codes.
Run the damn thing in to the dealer and have them look at it UNDER WARRANTY.
I am going to keep that on the back burner for now since I suspect they may be false codes. I drove about 500 more miles over the past 3 days and it runs and shifts perfectly. I need to find a good code reader. I am going to post another thread on that topic.
