Customer Question

Allison MH3000, 13 year old, 165k miles--no previous issues. Wouldn't shift out of drive, now engine wont start, no display on keypad except for red light in "econ mode" indicator. If by pass ECM and start engine, but "Don't Shift" warning light displays on coach dash. Checked all fuses and circuits and nothing seems to be wrong.
