I was wondering if 194-197 degrees is the normal operating temperature for the transmission in the 2011+ F150.

In warm or hot weather, after about 20 miles without a trailer, tranny temp should be around 190° to 200°. Working hard with the torque converter unlocked it should go up to around 205° to 210°. Under severe strain with the torque converter unlocked, such as dragging a heavy trailer up a steep mountain trail at less than 30 MPH, you could see over 210°. The red line is 225°. If it gets close to 225°, stop, put the tranny in neutral or park, elevate the idle RPM to 1,200, and sit there twiddling your thumbs until it cools down to less than 210°. Heat is the tranny killer, so never allow it to go over 225° if you don't want a dead tranny.

Seems like a hot issue (get it?) ha ha. i wish the salesmen at the dealerships or someone would have cleared this up when we bought our trucks. i mean who knew Ford was wanting the trans to run at 200 degrees? i sure didnt..

The number of lines (in the forum index) changes constantly. When you looked it was four lines down. Right now the thread you linked to is over 20 lines down and off the first page of the index.

Right! That is why I was asking this question. Don't these trucks have transmission coolers?? If so would it hurt to somehow get the transmission to run cooler seeing that heat is the killer of most transmissions??

You missed my point. There was a thread about the same thing on the first page when you started this!

There is nothing wrong with a trans temp in the 190-200 range. Yes, they have coolers, but the fluid will bypass them to keep temps up.
