All of a sudden, I'm not able to turn the overdrive off on my 94 V8tbird. I got my trans fluid changed before this happened and I think that it worked for a while after it was changed. It would help a lot to hear any ideas. Thanks.

I've got the same, Alternating front and rear. I have had no problems with it except when I tried to use the bright filliament in the inner bulbs, that caused the turn signal indicators to glow even when they weren't on.
