About 1000 miles back, it quit on the highway for just a couple of seconds. I was going up a hill and thought it might have just decided to downshift. Then it went back into OD and I have had absolutely no problems since.

This time is different. I was cruising along earlier today, and it suddenly dropped into 3rd. Now it won't even try to engage--it's completely out. The indicator light wasn't working before this happened, so I can't offer that to provide a clue.

I've read some past threads on auto OD problems and my first guess is that the problem might be the OD relay. But I don't have any experience here. Does anyone have some good advice on troubleshooting this?

I *think* there was a single click or pop (not loud) from behind the dash just at the moment the OD quit.

Thanks for any help you can provide.

Sure sounds like the od relay to me. Remove the glove box and tucked around the left hand side of the opening you will find the relay. Chances are if you activate the circuit by pushing the switch you will NOT hear the relay click. Remove the relay and then its cover and resolder the circuit board (or if you have $40 burning a hole in your pocket you could buy a new one). That would be the place to start as 90% of the time the symptoms you say it displays are relay related. Good luck.
