Oil & trans temps in 6.7 PSD
What are others seeing in oil & transmission temps when towing ? Went out for 1st long trip w/ out '15 PSD and oil temp was running between 210-225 and trans 200 to 210. This was at hiway speed (70 on NYS T-way). When I did the oil change a 1,000 miles ago, switched to Shell Rotella T-6 Synthetic.
Side note. As stated above, this was our 1st long trip that had a good hill on T-way. Cruise set at 70 and she never dropped nor did the rpm's go above 1750! Thought my old 6.0 was pretty good though she downshifted on same hill. With this new motor, Ive officially joined the "Can't get the smile off my face" crowd!!!
PS: Not towing, both temps run 200-205. Have a bug screen in front of grill. Water temp doesn't budge.
