Soon. I'm at 14.5K miles now. I plan to tackle this before the oil has degradated to the point it has sludged.
I'll throw together a how to. I have a '13 with PP.

does the explorer have a PTU? what is it?

I added the same SM section for the 2014 Explorer. You have a PTU if you have AWD.

Are there any additives that will help prevent oil degradation in the PTU?

Is there a temp sensor for the PTU?

Yes there is a temp sensor. The car becomes front wheel drive when you overheat it. Lol don't ask how I know.

Yeah, VI improvers are added to base stock oils by the manufacturer. I think the design of the PTU is what needs improvement. It is delivering torque to the front axles and the the rear driveshaft continuously of a 4500 lb car, using only a pint or whatever ridiculous capacity of oil. What remains to be seen I think is the effect on oil longevity with auxiliary water cooling equipped on interceptors and PP trim SHOs vs. non-cooled. Water cooling isn't even necessity. If you've got decent capacity, you can rely on a cooler, or even just cooling vanes on the housing to keep things cool. I've heard it's a headache to add the aux water cooling after-the-fact. Maybe it'd be easier to plumb in an inductive auxiliary oil cooler/radiator?

There is a procedure for the 13+ PP cars with liquid cooling. There is a fill and drain plug. According to the shop manual you have to remove the passenger cat to access the fill plug. I have yet to try this. I'm going to attempt it this weekend.

I have seen in FORScan the PID for the PTU temp gauge and the Lube life monitor (only available on 13+ PP) . I am still working on the equation for Torque Pro.

Hah. Sounds like a good time. Does it display any warning light? Or are we just left to figure it out on our own?

Would the non PP guys be able to use a PID for the temp?

Nope...there isn't a sensor to even read the temperature.  I have a 2011 PP and it doesn't have a sensor either.  The cooling and temp sensor was only added to the 2013+ PP

Lovely.... is it that much to as for a temp sensor in for something so fragile yet important. >:( 

I wonder if they would deny a warranty claim on this part if they dig to see if it has been tuned.

To me not having a temp sensor is odd. How would it know it's overheating. Let me look into the 13 SM.

With mine that has the cooling, I have seen temps as high as 95c (208f) when I'm driving a little harder. But most of the time is slightly below engine temps.
