Warning Light on 2002 Monaco Diplomat

I checked the manual and it states to stop and check all fluids. the coolant is ok , the oil level is ok, the oil pressure is at 60 at idle the coolant is 190 degrees. the transmission shifts alright I need to locate the dip stick for the transmission. I think it is a malfunctioning sensor. I drove it home 600 miles sometimes after a stop it would come on sometimes it did not light up nothing seems out of the ordinary? except the light is on the air pressure stays around 120 pounds and does not leak down when the engine is off HELP

    Have you checked the differential pressure indicator on the air filter ?
    My Roadtex computer threw a transmission over temp code on our trip back from Texas. Next fuel stop I checked the fluid level and it was way low. added 4 Its fluid, reset the fault codes in the computer, has been OK since.

    Does the manual state the name of the light? Is is a malfunction indicator light or check engine light? If it's not named in the guide can you describe the light or take a picture and post it?
