Sorry all. New here and have now double posted this. Attached is the photo of the indicator light.
1999 Bluebird, 8.3 Cummins, 3060 transmission
Engine temperature is good. Oil pressure is good. General coolant is fine although apparently mostly water. Bus has air brakes and retarder.
Someone said maybe hydraulic fluid was running hot? On a long drive home and definitely donít want to do my damage.
Had an inspection done in Colorado. Nothing related to this came up and was given the green light to make the long drive, but they could have missed something...
Any thoughts are very appreciated! Mods please feel free to delete the other post.
