Help - Overdrive Off Broken

I have a 1995 2.2L 4-cyl Camry Wagon, auto trans. with 257,500 miles. It runs like new, original engine & tranny. Without fanfare or noise the "overdrive off" quit working. The book says this can be a "circuit problem". All the connections seem to be in place, though. The transaxle shifts great, and I can drive the car this way, but in snow or ice or going down a steep hill it would be nice to take it out of overdrive to have better control or so the engine can slow the descent. The dealership mechanics replaced a "transmission switch" which did nothing except make them some money. It's exactly the same as when I took it in for repair. (They probably laid off or retired the mechanic that could fix it.) What might cause the overdrive off to stop working? What faulty part or connection should I look for to fix this? Thanks for any ideas that come this way.

Ummm, if the OD OFF switch didn't turn it off, then the dealer was reasonably correct to inspect the switch. Of course, we assume they would find that it failed before changing.

Have you verified that the lamp has not burnt-out?

I would leave it alone if it works, using the motor as a brake with that many miles is asking it to break. I never turn mine off anyway

Thanks for the clarification. If you're sure that the overdrive is not turning off with the switch and that the switch is working, it would be logical that the problem is the wiring from the switch to your control box - assuming that the control box controls the transmission and the overdrive lamp. It could be an internal problem with the control box in which case, it looks like you're not going to be switching that OD off. OTOH, my guess is you could get one from a salvage yard pretty cheap.

I used to switch the OD off when going down a certain downhill stretch but nowdays I don't drive down that road. If the OD did disengage without the indicator light coming on, I'd just leave it alone. Using the OD to slow down on ice and snow would seem to indicate that you might be going too fast on ice and snow. OTOH, I've never driven in ice or snow, wadda I know? :-)
