Any good ideas how to progress? It worked perfect and then intermittent and now won't shift up at all. OD button on shifter works, at least the arrow lights up.

could be that the wire inside the shifter itself is frayed and not making contact or the solenoid is shot... but first check ur OD relay to see if its firing up...thats in the dash under the radio....I eliminated mines by jumpering it...it just gives problems....
