I read in a thread from 2011 where an individual was having this same problem. Said he was taking his vehicle the next week to a mechanic. He then followed up later that it was fixed and no more blinking but never said what was causing this issue with his vehicle. My OD light blinks at random intervals but drives and shifts just fine tranny fluid is good. My question is that has anyone had the same problem and can shed some light. I know it could be several things. 1998 GT vert. 86k all origional no aftermarket parts at all except for new intake manifold and wheels.
