I have a 1/2" drillbit I keep in the ashtray for turning off/on my O/D. The button has gotten to where my finger won't turn it off or on, but a solid piece of metal or hard plastic will. I am building a house where there's tons of billowing fine, baby power-type dust and it gets into everything, and it is that the button has got gummed up. It destroyed my CD and casssette player already. Anyway, I wonder if you might also have a gummed up button on your shifter.

All the O/D off button does is ground a circuit, that suggests to the PCM, that you don't really want O/D for a bit..... (until you push the button again, or, restart the truck.)
With the ignition on, and the button pressed, see if you are getting power (12 volts) at the PCM connector, pin 10, Orange wire with white trace.
