Christopher:
A couple of things to check that I learned while going through my OD
project. After you refilled the trans. and drove the car around for a bit,
did you then re-check the trans. level to make sure it's all the way up?
When you drain the trans. and re-fill it and run it, the OD unit takes up
some of that oil. I understand that if the level is not all the way up, OD
will not even hint at working. Also, I've been told, and don't know if
it's true, that you should use straight 30 weight, not multi-grade in the
trans. I don't think this would cause your non-operation, though.

Could a wire come loose from the wiring that goes from the column switch
to the relay, etc.? Just an idea as my right turn signal ceased operation
a couple of weeks ago. Inspection under the dash revealed that the press
in connector for that wire from the harness to the switch had just worked
itself a bit loose. Plugging it in all the way solved the problem. Just a
long shot, but something to check as the connectors function the same way
and if your column switch isn't switching, no OD. Have you been under the
dash lately? Maybe this could have come loose.

Good luck.
