Hi ! I have a ford contour GL 4 cyl. It has a similar problem of O/D flashing and hard shifting whenver the O/Dlight flashing. The O/D light has a mind of itself. On 60% of drives it flashes.
I got the AT fluid replaced, but there has been no change in O/D light Since the day it first flashed (@1111000 miles) until now (141000 miles) the O/D light has'nt chnged its behaviour. I even showed it to mechanics, the best they could say was "smething wrong with the traany", one guy thought it was a problem with a solonoid in the transmission.
