How long do you need to brake torque it to get the temp up, or how long would I need to drive it normally to get to the proper temp?
He's in Tex you're in Mich so the amount of time will be different, but if you drive normally for about 30 minutes this ought to bring the temp up to the right range, but you must have something to measure it to be sure.
With it being almost winter here I would probably have to do a little more than 30 minutes.

We bought the Explorer new and have done this at 12,000 mi, 10,000 mi and 10,000 mi. intervals to clean out the initial factory fill and wear material. This last 10,000 mi change the magnetic drain plug was totally clean even though the fluid was a dark purple gray, not the clean red of the new fluid. Of course I'm assuming the initial fill level was correct. Since the shifting quality has been great I'm assuming the refill amount is more than sufficient. My Ford dealer will not do a drain and fill, only a complete "flush" or fluid exchange for over $200 using bulk LV ATF fluid. Do they even clean out the lines and tanks of previous ATF fluid between fluid flushes/exchanges, who knows. I would not want to mix Mercon V or any other transmission fluid into a transmission that needs Mercon LV.

Thanks for the idea. Does your Explorer have the 6F35? What fluid have you been using?
I recently changed it on our 2013 fusion at 65,000km with the 6F35. Just done cold drain and fill, took 4 liters of motorcraft mercon LV.
