Axle Gauges

All these trucks should come standard with a full gauge package.
I don't have a boost gauge or suspension gauge..but I do have a transmission temp that never moves.

 

It’s probably broke ....

full load even in the winter the gauge should move.

 

It moves in summer,but not very much..useless !

 

Yeah but if the metal parts inside begin to come apart for whatever reason, and metal bits and shavings start to get circulated inside with the gear oil [or what's left of it], the heat will climb much higher, and pretty fast. And hopefully you could see this before you endure the catastrophic failure that is coming soon.
