The light is sending you a fault code. Count the number of
flashes separated by a short break. Should be a 3 digit
code. In any case, the ECM has detected a problem with your
transmission. Early diagnosis may lead to a relatively
simple and inexpensive repair. Continued operation with the
lamp illuminated may result in extensive further damage to
Good luck, I dont mean to be a party crasher, but my buddy had one that the
OD light would come on and downshift it self and act like it was in labor.
No one could tell him why, this also seemed to happen to a newer one he
bought to replace the 96. He traded it back to the guys that sold it to
him in the first place. Hauled it within a mile so it wouldnt warm up and
drove it on the lot. Happy trails!
I'm working on the girlfriends 99 windstar. Overdrive light comes on
steady during cruise and car exhibits the same symptoms... engine starts
to sound sick. Wondering if this could just mean Tranny needs a band
adjusted or a pump replaced? Can't find a Chlton's or Haynes that dares
tell one anything about a tranny. Otherwise runs great but has always had
P0171 and P0174 DTCs... engine running lean and can't find a cure. Maybe
they're connected in some way?
