Trans temp gauge reads '0'
'06 Allergo Bus, Allison trans, no reading on trans temp. It's a cold trip heading to Az but not that cold. Just looking for a little assistance as where to look. Bob

Not knowing which Allison you have, I did a quick search. Looks like most are single wire. The location of the sensor varies. I would try to locate the sending unit. disconnect wire, check gauge. Next ground the wire and check gauge. Could be bad wire or defective sending unit.
