Are you talking about the Overdrive Light?

The OD light on the stalk is kind of like what your "Check Engine Light" is for the motor.

Only it flashes when there are codes present showing problems for the transmission.

Something's wrong in there, get it scanned with a good scanner or take it to a trans shop.

I had a 2000 model that had developed a short in the wiring. The light would randomly go off and on. If your light is flashing continuously its a warning signal.

Mine flashed towing my fiver up a long hill on a hot day in Idaho almost a year ago to the day. The 4R100 AT does not like heat, the stock tranny gauge only reads hot when it is way, way too late, and the stock tranny cooler is inadequate. My 2 cents: Check your fluid and replace if even only halfway bad, and for future reliability install a good tranny oil cooler and a Magnefine filter in line ahead of it. The clutches in the tranny disintegrate under high heat stress and will clog the cooler without the Magnefine. There are fancier setups for cooling and filtration but the greater cost brings diminishing returns, IMHO. That's what I did and I've been fine since. Parts and info at dieselmann's Store: Transmission

It also could be wires chafing in the steering column. You can tell if it is overheating or a wiring issue by the conditions under which the flashing occurs.

Good luck!
