Egts,most so far unloaded going up a steep but short hill around 25 mph 1000 degrees,transmission got to 200 in that time. Hill was maybe 1/4 mile long. At highway speeds in the mountains I can get 900 and 160. I am moving back to the east coast soon,should I be worried about these temps?Will be towing a 6x12 enclosed trailer and what ever will fit in the bed and cab. Whats the max sustained egt the CTD can hold?I know to back off the transmission by 200,anything to help bring these temps down a bit?Noticed the transmission cooler a the rear of the engine block,why is it there?
