I driving down the road and all of the sudden OD starts slipping. So I pull over and when I try to back up it just binds up light and won't move. First, second and third seem ok it seems that OD slips and reverse won't work. Any Ideas. This is my daily driver so i need to know ASAP!!! Am I looking at a new trans or maybe somthing like small? 99 f250 4wd 152k I just bought this two weeks ago man am I pissed.
