'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.

It will read cold most of the time. It takes sped load and torque to get it up to show much temperature. Climbing a mountain it will show especially if towing a vehicle. In hot weather it will, of course show earlier. Took ours to Freightliner then Allison shortly after buying it because we thought the trans temp gauge was not working properly. All was fine. That was 2005 model. newer ones I cannot say. Take yours to the factory or to the chassis mfg service service center and have it checked.

Several years ago I had the same issue. The wire connector had come unplugged from the sensor on the transmission. I think it was on the rear of the Allison 3000, but was easy to reattach.
