The OD off light started flashing on my 1997 f350 psd while I was plowing in the last storm in Ma. In limp mode in set up an oppointment at a local tranny shop ( one with I trusted) I was told my touge convertor had blowen taken out cluthes etc. 63000, miles is about my estimate on how long your auto. tranny will last based on my experience and a friend who has three of the same trucks in his landscaping business.
