Most likely you have an Allison tranny and you are talking about the shift pad. There is a 12v power wire from the Engine Control Unit (ECU) to the key pad that powers it up. Quite possibly that wire has broken somewhere. The ECU is in the rear and the shift pad is in the front. Lots of places it can be broken. A service shop can check that out and even run a new wire.
