OD off turned on by itself?
Is there any condition the pcm can see that will shift the truck into OD off on its own? I was driving my truck, empty on flat ground, when the trans downshifted on its own. Creeped me out so I went to neutral and did a guage check and noticed the OD OFF light on. Trans temp 150, engine 160, boost 7, pyro 850, volts 14, oil pressure 40, nothing out of the ordinary. I just turned the OD OFF *off* and put it back in D and went on my way. It didn't do it again after that. I smacked, flicked, and generally messed around with the switch to see if it was flaky. Seems to be OK. Any ideas?
