Thanks Tuga! Actually my keypad unit looks more like this one: Allison Gen IV Push Button Shifter / Pad
I went back to the bus this morning armed with the info from all the responses to this thread so far. Alas - no luck! I called W.W. Williams (a Detroit/Allison service facilty) in Atlanta and the guy there had me put the tranny into the code reading mode and read him what the screen showed. The good news is that there were no active codes. The bad news is that they can't get road service to me until late this afternoon. My guy at Apalachee RV thinks it may be a relay or solenoid (?) but can't help me further without me bringing the bus to him (and of course, it won't move). I'm not ready for a 60 mile tow, so I'll wait on the W.W. Williams road service and keep my fingers crossed!![]()
