Transmission "Do Not Shift" Light and Code 22 (Speed Sensor)

[Mike McMahan]

David, I chased a do not shift light for months. mine would go out
when the coach was started and come on when the bus was shut off.
Finally found loose wire on back of ignition switch. Low voltage
and bad grounds do weird stuff to theses beasts. If you are unable
to solve I'll get you the phone number for Industrial Transmission
in Waco. They have the best Allison techs I have found and are
usually willing to help you on the phone. Mike McMahan 1989 PT40
