If your overdrive light is flashing, it is trying to tell you that there is a transmission failure. You will have to scan your powertrain control module to find out what is wrong.
Check the wiring goes to the button or replace new switch button
I have ?nd it says solenoid switch. But I really don't know because I remove the old engine and replaced it with a 05 p71 engine. In a 03. So the trans is for a 2003. I think I need a 5w.
