One thing I have noticed is the transmission heats up when cruising at road speeds for 20ish miles. Not bad on the pavement but on the gravel roads with more resistance my trans temps reached 205 and the engine temp was about 180 in sub zero temps. I have had it on a couple 20ish mile gravel road trips and both times the cooling fans would be running but only the transmission temps warm up not the engine. Probably designed that way but kinda scares me when it gets 90f out if the fans are running at -10 to -20 degrees.
