I'm working on my 2006 lbz 2wd 26,000 miles on it and it went into limp mode and won't shift out of first, won't unlock the doors in park, day time running lights stay on constant and says drivers door ajar all the time. like I said above it threw a po700, po708, and a po722. Tranny has never been limped before this and no tuner or any mods done. Fluid is also full and smells normal. Any help is appreciated!

Sounds computer/electronic related. I would start out by disconnecting both batteries for at least a few minutes. I fix many computer equipted devices and some time they get in a logic state that cannot be recovered unless all power is drained. This is the eaiest and lest costly step you can perform. From here it gets harder like possibly wire chaffe, computer took a dive and so on. You can also disconnect all of the major plugs going to the computer and check for corrosion and reinstall.
