I'm not sure about the fluid question, but I think new fluid with it's "highly modified friction" additives is the way to go.

I read that the motor mounts have to be loosened to get to some hidden pan bolts. I didn't have time or I would have done it myself. So, I opted for the flush method.

I called ford and they said if it had not been changed do not to change the fluid now. They little pieces of clutch material in the fluid was acting like the friction surfaces and new fluid would cause it to slip more.

My question, with 80K and no problems, will I cause any problem changing it.

Can't speak for Ford but what you speak of did happen in my Mom's 86 Buick Century. She had tranny problems and a shop changed the fluid and after getting home, the fluid change made it worse. The dealer at that time said it was possible.. I had never heard of it before. She had to have the tranny rebuilt. I am not sure how many miles it had at that point in time.
