Bus has been towed to closest Allison repair facility in Kingsport, Tn. (Clark Power Services). Thanks for advice and after removing axles used cardboard for axle covers. This helped with the lossy of oil!
The Chassis wiring has been checked and is good. No codes in ATEC system!
We are suspecting the keypad or ECU. Currently Clark Power Supply is trying to locate a used keypad for testing from their other shops. Any ideas where to find a keypad ( pn-23048155 28/93)? I may need a rebuilt or used unit.
Looks like the bus will be in TN for a while.
