Hello...I am new to these forums and I have had the same problem with the O/D Off light flashing. I drove it about 3 or 4 miles with the light flashing. I pulled into an empty parking lot and read the owners manual. It said turning the engine off and turning it back on resets the O/D to on. I did that and the flashing stopped and stayed off all the way home. (About 10 miles) I had no issues with the transmission or RPM's. Everything seemed normal.
You can check the gear column for exposed cable .
Or take it to the dealer to fix it . I did everything that I could think off but the problem still . So the truck now at ford service center .
Finally I got my truck and running good , flashing gone, smooth shifting, .
The problem was the harnesses from the transmission and the abs sensor harness.
Thank you guys for helping .

I know that and I considered and I let the mechanic see your posts .
Thank you Mark .
Not surprising.
Go anywhere for help and give them info off the web and you instantly loose credibilty. I fix network issues, i still start at the beginning even if you tell me your isp checks out ok..

I told him because he asked me what happened and what do I fix or replaced or checked , Before I went to them . And he checked every thing all wires , connectors , pcm , and so many other things .
The X is fixed and am happy so if it's not fully fixed, I got a 6 months warranty on the job .
Mr.Mark the truck do it again today. They changed the harnesses and the connectors plus the sensors again , so am lost now .
I have a wrecked 2000 4x4 5.4l expedition that have a new 2k mile transmission before my brother in law flipped it . Can I swap that transmission In the excursion . I think both trans are 4r100 .
If your truck is a 4x4 and the Expedition trans is a 4R100 it will bolt up. The 4R100 from a 5.4L has less plates in some of the clutches so it may not last a long time.
