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

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?

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.

After filling up with fuel one night and, upon starting engine, a stop engine light came on immediately. Checked around coach and then proceeded to campground nearby. The next morning upon start-up the light had disappeared. I was a little hesitant to get on the road to my destination, and proceeded with some caution. Didn't have any further concerns. Never have had that again. Good luck with yours.

What transmission do you have. If you have the 3000 or better, you can check the transmission fluid with the shift selector pad. The manual says it is more accurate than the dipstick. The transmission has to be warmed up to do it. Just hold the up and down buttons at the same time. It will give a code indicating the level. The exact instructions will be in the allison manual that came with the rv. If you have the 2500 series or less, this feature is not available.

Please post what engine tranny combo you have. Also, let us know what you mean by a warning light. On mine the red light comes on accompanied by a loud 'ding'. As it flashes, it says why. i.e. check engine, fluids, water in fuel etc. If it's just a warning light with no indicator I can see where that would be irritating as well as disconcerting....Dennis

On my previous coach I had that same light that says warning come on a couple times. I had the codes read and it turned out to be my Caps Fuel pump was having problems. Yours may be different but I think that warning light warns of low levels of fluids or a code being stored.
