The overdrive light in my car has started flashing whenever the car is turned on. The light will turn off and stay off as long as I'm holding the button down, but the button won't stay engaged.

This sounds like you have a turbine shaft speed sensor that is going out but to be sure lets run the codes to see what comes up.
