overdrive light blinking

I have a 98 expedition. My overdrive "off" light blinks in a series. My overdrive does not seem to be working. Sensor? or more serious?

Thanks,
Mike

I have a 97 4wd Expedition and the overdrive light started blinking a couple of days ago. When the light is blinking, it feels like overdrive is kicking on and off. Any updates on what the fault codes mean?

I have this same issue with my 99 expi, the OD light light flashes after the car shifted some gears. What do i need to get this fixed? Will this get worse?

The first thing you need to do is get into a shop or auto parts store and get the codes read from the trans. This will give you a starting point. If your lucky it is something simple like the speed sensor otherwise you may be looking at a trans rebuild or replacement. You definitely want to look into this before your stranded far from home. Having said that i will say that on my 99 Windstar the OD light has been blinking for over a year and i can see a difference in rpm's when it does. One day i may go buy a speed sensor to see if that solves the issue.

I have notice if you turn off the ignition and restart the vehicle it gose off and may stay off for sometime or may come on in a couple miles. while on if you try to disingage od the vehicle jerks. what is wrong?
