NV5600 Temperature Question

[griggsd]

With an auto, fastcoolers & guages are probably vital when towing heavy, and MadBomber's spot on that only guages will give your constant awareness under all circumstances. I've not exceeded 205 degrees on the transmission or xfer case when towing in Colorado (taken immediately at the top of a long grade in summer) with my 5600. If I saw much higher (220+) I'd look into guages.
