My girlfriend noticed the overdrive off light came on about a year ago. And I noticed it a month ago or so. And again today.
I checked the fluid level and it was at the bottom hash line so I put in a half a quart. I checked the level again and it was about 3/16 of an inch above the full line.
I started to notice an oil spot directly under the tranny coolant lines probably within the last 6 months. It could have been longer than that I just didn't notice.
I started parking the truck in a different spot and noticed the oil spot followed.
I crawled under and had a look at the tranny coolant lines and noticed they were wet with tranny fluid. The tranny lines run to the radiator and if I remember right they go to a little matrix box about 12"x12"x1". The lines that run from the little matrix box are rubber line. The hose clamps at the top seemed tight the 2 at the bottom seemed loose so I tightened those ones. I also notice one of the hoseses seemed to short and had been rubbing on the radiator houseing.
I notice the tranny was shifting hard a few times at slower speeds.
No check engine light. Just the O/D off flashing.
Hopefully this is something simple like a sensor.
Thanks

Not the first time I had to replace AT coolant line, but in road salt areas, more like 8 years instead of 16. Not quite sure about this Ford, typical in other vehicles, its the brake switch with dirty contacts, have to make good contact with the service brake pedal up to stay in OD.

Well its been a week and I didn't really get anywhere. I had to relearn how to check tranny fluid levels. After haveing that manual 5 speed for over 5 years I litterally think I forgot how to check automatic tranny fluid.
After a few days I realized the temp gauge may have said normal operating temp but that didn't mean the tranny was warm. I only live 2 miles from work.
So I started checking it after the truck had been run for 1/2 hour. I finally started to get a consistant reading.
It was reading about 3/4" over the top hash line. So now I have to drain tranny fluid. I think I understand why transmissions are sealed now a days.
I thought about just letting it leak back out. But I think I may have some what fixed that leak buy tightening those hose clamps up a 2nd time.
I guess I'll keep any eye on it. I drove it for about 30 miles yesterday and it drove flawlessly.

"you need to have the codes read then i can help this should be in the transmission forum but i'll check back in"
Doesn't there have to be a check engine light in order to have the codes read.

Not necessarily. You could have a pending code in your PCM. When the PCM detects a fault, sometimes it will store it as a pending fault and not light up the MIL unless the fault remains for a period of time. You can read pending faults if you have the right scanner.
