What did you use to read the codes the first time? What engine do you have in your rig?

You need a scan tool that will read codes from the Transmission module. If that light is flashing there are codes set. Snap On, OTC, or the Ford IDS will do it.

The Innova scan tool will only read generic OBD codes of which none are transmission. You need to find someone with one of the high end or OE scan tools. A real mechanic will have one.

Flashin O/D light

I had this problem a few years ago. There were a bunch of suggestions somewhere in this forum....somewhere. There was a lot of big scarey talk like "limp mode of a dying transmission" and torque converter problems.

My stalling and flashing went away when I changed the alternator voltage regulator. I did it for an unrelated issue and the stalling and flashing were gone. Cheap and quick swap out.

Beats me why, but it worked.

Good luck.
