skandocious posted something recently about the dome light fuse being blown can cause the transmission to go into limp mode, and the OD light to flash..

Other than that, I would think mebbe clock spring?

Did you try to run codes?

there are two connectors at the trans
clean and check both for full contact
also check all grounds
do you have any drivability issues
read the codes from computer
sensors on the engine can cause issues with the trans
also check out www.fordfuelinjection.com

Isn't the overdrive light flashing a "trouble code"?? Thought I read that somewhere.
Might need a tranny shop to decipher it.

flashing od can be a code or it can indicate
a bad connection as mine does
I have cut the wire to my trans pressure regulator
and that causes my od lite to flash
no codes in comp. though
