Today on my final leg of my trip home from Key West to PA my transmission temp light came on. I was on I-81 in PA (very hilly) climbing a hill going about 70 mph and the light came one for literally 3 seconds and then went off. The second I noticed it, I slowed things down to about 58 and then had no further problems or warning lights. Engine temp stayed fine the entire time. My rig is a 2003 Winnebago Journey DL with a 330 HP Cat 3126 paired with the Allison 3000 on the Freightliner XC Chassis. Has anyone ever experienced this with their coach? I had all filters and everything changed only about a month ago. Does anyone know at what temp that light would come on? Do you think I burned out the tranny fluid or even worse done damage to the tranny? Like I said all seemed fine and light did not come back on once I slowed up. I appreciate your help.

Just curious..have you tried to read the OBD diagnostics codes from the console ?

Im not sure what port you use...here is an example from amazon

Take it in to a heavy truck shop..and they can read the diagnostic codes.

I douubt you caused any damage. Light was on such a short period of time. Do you also have a manual temp gauge? My temp light came on once and the manual gauge indicated it was hot. I backed off like you and it cooled down quickly. Mine got hot because I forgot to take it out of the economy mode while on hilly raods.
