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

[David Hanvy]

Mike, Thanks for the input. I'll check the ignition switch wiring on
both the front and rear remote. I would appreciate the contact info re
Industrial Transmission in anycase. The local Allison rep is the
Houston Stewart & Stevenson shop. I have spent more than a reasonable
amount of $$ with this outfit on other type repairs in the past.
