Most alisons have seperate power supplies to the button pad and computor, then they talk "computer" between them rather than run real power. So check for a power supply to the button pad and power to the trans computer. If you have the ability to get the trans scaned you will probably get a comunication fault off the button pad. Any way, bad fuses, bad 12 volt breaker, bad ground are the places to start. All from the front power distribution box (fuse box) for the chassis controls. Good Luck |
