Normal Trans temps
Hi all, just picked up a used 2012 F250 SD 6.7 PSD , 6 speed auto. What should the normal trans temp be? I was watching the trans temp in the info center and it was showing around 190*. This is under normal driving conditions.
Thanks,
John

iirc normal operating temp is 80-100 over ambient temp

That used to be the case until the 5R110 transmission came about in 2005('03 for diesel models). Both that and the 6R140 the OP has use a thermostat that regulates temperature. The OP's transmission will run 190* in the middle of winter in Alaska.

Thanks for the reply. My old truck (03 Ram 2500 5.9 CTD Auto) always ran around 140* under normal driving and 160 - 180* when towing. We'll see what it does when I tow the trailer for the 1st time in a few weeks.

That's about the weight I pull also mainly in Florida. I have seen just over 210 at times depending on ambient temp. I have seen other threads that indicate the tranny fluid is designed to run this hot and hotter without any adverse issues.
Happy towing.
