Trans Help

[firedude512]

ok, i own a 2001 f-350 diesel 4x4, well last week when i left work the od light started flashing, before i could turn around and get back to my shop, i got stopped on a hill and the truck WOULD NOT move, it was just rev up and move the slam to an idle. you can shut if off start it right back and the probelms goes away for about a mile then comes back. it has an output speed sensor code in it, replaced both sensors and still does it, then i took a looky at the data and with the truck in park you can rev it up and it shows ur moving 119 mph and not even moving, what could cause this, plus when you run a koer test you come back with vss out of test range, HELP!!!!!!!!!

did you replace the sensor in the diff or the one on the tranny? that code is for the one on the tranny, but VSS comes off of the rear diff one...
