God have mercy on your soul, I am a mechanic too but I have to write on the computer, I think I know what you're trying to tell me but I am not sure I will guess, the problem that you're telling me is when you give it full throttle the transmission does not kick down to passing gear? If that is correct, there is a switch behind the pedal that you can test to make sure it's working you will have to remove the carpet to get to the switch, let me know if I can assist you anymore.
