Default Need electrical help...started with 4x4 problems.

I have an 08 ram 1500 hemi. Its been near -20 for past few weeks, except a few days ago, it got warm and slushy. some big puddles on the backroads i live on. That night my 4x4 started acting up. would go in and out at first, but 4wd light remained on dashboard. It turned cold again outside next day, light is still on, but wont go into 4wd. power windows quit for a short while, and voltage was reading high. This morning, the truck started for 3 seconds, shut off and will not start again. red lightning bolt is now on dash. no service engine light though. checked fuel pump, and all obvious connections, and fuses. error code p0882 . I'm just a backyard mechanic, and the nearest dealer is 100 miles away. I hate to dump cash for towing, and troubleshooting if there is a chance of fixing it myself, or at least knowing what my options are. Any advice would be greatly appreciated!!

P0882 = TCM (transmission control module) voltage input low.

I've attached the diagnostic routine from the 2008 factory service manual.
