The over drive light in my automatic Tribute is flashing. But the gears change quite smoothly, and it goes to all the gears with no problem. I was thinking it might just be old fluids or an electrical problem, the bottom in the chance stick doesn’t seem to be working because nothing happens when I press it.
I’m wondering if anyone else had the same problem and how can it be fixed. Cheers!

 

Take it to Mazda for a diagnostic code check.
