    Transmission air pressure is below 72.5 PSI

    Once you start the truck and build up the pressure in the air tanks, it should go away. If it doesn't go away, I would listen for leaks down there and spray soapy water. If you can't find leaks and the tank is holding air, then check to make sure there is not a one way valve or something installed backwards or a blockage in the lines.
