Hey guys, I'm having a real tough time with my 2013 chevrolet silverado 4.8L V8 the engine is an L20 Vortec. I'm getting all these nasty fault codes and they are intermittent and usually start acting up when I'm driving in the city. When the engine is warm and I stop in traffic, or hit a crawl speed. The truck normally kicks into "limp mode" and all these fault codes start up ex. P2544 ( regularly) P150C, P069E, and recently P0700. now there is a list of communication codes, but normally its U0073, U0100, and U0109. I've gone to a few auto shops and they kinda said god luck, The dealer had no idea what i was talking about, started with cleaning all my grounds, as well as my fuses, everything seems to be in order. My brother (who is a mechanic) seems to think my TCM is at fault and not working, but I'm hesitant to call that the problem because Im pretty sure its in my transmission which seems like a fairly big job. Everything else runs fine and there is no problems at all when the truck isn't acting up. Any thoughts or suggestions? I'm pretty desperate to fix this as I plan on taking it to Alaska in july
