Do you have the ability to get the codes checked? From what I have researched it could be any number of issues, instead of throwing parts at it, it's best to just have them read. Cheap and easy test would be to crawl under and make sure all connections are made and no critters have chewed threw the wires. My neighbor had rabbits chew his tyranny wires three times. His mechanic ended up putting wire loom around them coated in axel grease. The rabbits haven't been back.

The overdrive off light flashing means it's throwing codes. I'd get em read and go from there. Could be anything from a sensor going bad to.............well let's not talk about the other end of the spectrum. Mine flashes like that pretty often because my intake air temp sensor isn't plugged in so the truck throws a fit about it haha
