My question is in regards to the transmission over heat light on my 2010 dodge ram. My trans temp got up to 275 and the light came on while towing, we turned tow haul mode on. ( it was accidentally left off) and everything was good and appears to be no adverse effects to the tranny. My mechanic told me as long as I pulled over when the light came on to let it cool its fine because thats the way dodge designed the warning system. Yet some people say once the lights on its done permanent damage already. Which is it? After driving all the way back home towing the same load tranny was fine. (Between 190-210 deg) depending on hilly or flat terrain. As well as driving with no load shifting just as good as it ever did. I checked the tranny fluid on the dip stick it doesn't smell burnt in any way and looks brand new. No sign of brownng or nothing. Whats everyones opinions? Like I said once the temp light came on I pulled over within 30 seconds and let it cool.
