I'm gonna assume you checked the fluid level.
Myself, I don't know... but the last time my O/D light was blinking, I was shortly putting a new trans in it...
The guy who did the rebuild said there were trans trouble codes set, ones that my buddy's computer could not read, even though it reads my other trouble codes. My point is, if the light blinking, it's the transmission's way of telling you something is wrong. A good trans tech should be able to check them for you, and steer you in the right direction. But, most likely, you're gonna need a trans soon. Welcome to the weak link in the PSD world!!!
