Interesting I have a 2001 2500hd and a 2014 2500hd both with the 6.o gas, under 150k miles and both trannys run very hot pulling a load up into arizona in the summer, running full syn, tranny fluid changed about at 50k . if im not careful they'll go over 260 , the 2014 is dealer maintained, im looking for after market coolers for both trucks.
