I have an 11 lml and it's pulling codes (randomly) p0880, p1762, p0563. The truck will drive fine, and then it feels like it's in and out of gear, shifting very harshly. If I'm driving at parking lot speeds sometimes the wheels will lock up, and if it will move sometimes it feels like individual tires are having brakes applied, or as if I'm in 4wd turning full lock. I'll get shift inhibited and nothing I do fixes it. While the truck idles the idle jumps around from about 650 to 900. It feels like it's adding rpm to put the truck in gear. Whether I leave the truck on or have it off, the problem goes away in about 30 minutes and then the truck drives fine. It's doing it right now but when I hook up my Autocal it won't pull any codes at all. When I try to change tunes on the Autocal I get the $0502 error. Prob ably not related, but never had any issues with it until the drive train started acting funny, so who knows. Truck is deleted, running efi live from synthetic. Any ideas?
