Get an OBDII scan tool hooked to it and see if there are any codes stored.
Fords will show tranny shift and TCC and o/d error codes this way.
Most people want to condemn the tranny when the light flashes. And most tranny shops and many dealers will tell you you need a rebuild to the tune of about 1800 bare minimun. Up to 3500.00 dollars.
I think it depends on how nice the vehicle is and how nice you are dressed. Get my drift?
The two most common causes and easy replacement parts are the VSS vehicle speed sensor and the MLP manual lever position sensor. Also called the gear selector position sensor and sometime the neutral safety switch. Ford calls it MLP.
Both are easy to replace. If you find any codes relating to VSS or speed input signal. Or MLP or gear selector. Replace the corresponding one.
I don't like to throw parts at car problems.
But this might solve your problem.
ALSO. Under the hood in the black fuse and relay center on the driver side near firewall. There is a IIRC
Powertrain control (module ) relay. They are something like 7 bucks from ford. And I have seen a 99 Explorer that did all sorts of shifting problems and propped 5 codes at once and would only go about 20 mph. All caused by this relay getting hot and breaking down.(Opening when it should have maintained energized connection) I'd try thay too for the 7.00.
