2003 Exp - O/D Blinking

The blinking O/D light indicates a transmission problem. This is covered in the owners guide. THe guide says something like:

"Overdrive off: Illuminates when the overdrive function of the transmission has been turned off, refer to the Driving chapter. If the light flashes steadily or does not illuminate, have the transmission serviced soon, or damage may occur."

Exactly what vehicle do you have. A 2003 Exp could be an EXPlorer or an EXPedition. Potentially different transmisisons and a different set of failures. Is it 2WD or 4WD? Which engine?

I have a 2003 Expedition EB - 5.4L Triton 2wd

Join the Expediton Owners Mailing List and ask that group. See .

My suggestion is to have the codes read as soon as possible. It might be an easily corrected problem, but letting it go could lead to larger problems later on.

Took it to the dealer and found out I had a P1783 code - Trans Over Temp Condition. Service advisor stated it was a solenoid issue causing the over temp condition. All fixed now... Driving real nice as of picking it up early evening.

This is what my service order states:

"ROADTEST EECTEST CODE P1783 TRANS OVER TEMP REPLACE MAINCONT CONNECTOR FOR CODE P1783 ROADTEST AFTER REPAIRS"

I would suggest not driving until you can have the codes read...

...been there, done that, and bought a 3K t-shirt!

That bliniing light is telling you there is trouble with the transmission. Technically, the light is telling you the transmission THINKS it is having trouble. The trouble may be real, or not. I would proceed as if there is trouble until you determine without reservation that there is no trouble.
