Ecoboost transmission temp

[riven1950]

I just purchased a new 2013 F150 Ecoboost. I have read the manual and do not find a reference to a " normal " or " excessive " numerical number for tranny temp. It only refers to the gauge moving to the danger area if overheating occurs.

After running 70mph on the interstate for an hour or so on my first trip the numerical temp was 194 +/-. The gauge shows mid range or normal.

Just curious what other ecoboost owners are seeing as a normal tranny operating temp. I ask because mine runs 15-18 degrees warmer than my old F150.

Yes, I do realize different engines operate at different "normal" temps. It just seems if the manufacturer gives you a temp gauge they would also tell you what is / is not normal ( a range ). Surely individual engines of the same make /model would have similar operating temps. wouldn't they?

Thanks folks, at least now I know mine is within the new normal range. Thought it was as the gauge is planted right on normal after full warm up.

The newer transmissions are all regulated to run hotter to improve efficiency. Actually, same with the engines too. 209F is the new normal T-stat full-open temp, where 10 years ago 190F was the norm, and 20 years ago it was 180F.

I've only run unloaded so far (break in). I am typically at 175 on back country roads putting along. Have gotten to 190 in city driving.

I've never seen over 205F with an 8800lb 5th wheel but that's in the midwest with no long grades. I also have the max tow/HD payload package so if you have the standard towing package without the extra cooling, it may run warmer. Unloaded, it's in the 195F range, like you have seen. I wouldn't worry until 230F but I think you'll have a hard time getting there.
