Question: My Overdrive has stopped working, i.e. - when I hit the button on the shifter, the O/D OFF light never comes on, and again when I depress the button, meaning I can't even tell if overdrive is even working now. I DID get the overdrive light to flash when checking tranny codes, and thankfully it continuously blinked clear. If my button has gone bad, what will I need to do once I take the shifter out?
General info if anyone needs it: 1988 Turbo, 3.91 LSD Automatic
