I was driving my PW today it started doing funny stuff. The transmission would not go above 5 the gear. At first I thought it had somehow been shifted into low range. The axle unlock button was blinking and would not stop flashing. I cycled the transfer case lever several times and all seemed to be fine. Finally I unhooked the negative on the battery for a few minutes and then everything worked fine for 500 mile drive home. The manual gear selector had no effect on fixing this until the battery was unhooked.
