Maybe a wild goose chase or worth considering. At ~180k miles, my Ford Expedition started failing to down shift from 4WD-High to 2WD-High. After much reading, I learned that failing transmission *sensors* can cause the problem, and that disconnecting the battery momentarily can cause the computer to reset things and get back into 2WD. It sounds off the wall, but I had ~4 lockups that were all solved by disconnecting the battery.
Thanks. Good to know this tip. If ever all else fails it might be worth trying to disconnect the battery.
