So I just wanted to share with everyone about my experience with draining and filling the PTU on my 14 PP.
A little background... I am the second owner of my SHO. I purchased it back in '15 with under 17k on the odo. Whether or not the fluid was changed prior to my ownership is anyone's guess but I will side on the assumption of no. I have roughly 45k on the odo now and have never changed it so I was getting anxious. I drive about 50 miles round trip from work and they are all highway miles with speeds between 65-75. On occasion when driving around town I'll open her up. Just some background of my driving habits.
My first step was I went a grabbed some 1/4" ID fuel hose from autozone, 2 1/2' worth, as well as some 5/8"-1/4" hose clamps in case I didn't have any.
The thought of how much a pain it was to fill on the PP had me thinking and after reading a couple of posts it seems like people were trying it and never really reporting back. At least not what I saw. The method I am mentioning is to fill it through the PTU vent hose after extending it out to the brake booster to which mine is located. I was able to pull the OEM vent tube off and managed to snake my arm in a way to install the new hose but was not able to tighten the hose clamp but after thinking about it I didn't want to tighten it just yet.
So I couldn't find anything to protect the O2 sensor and I didn't want it getting all over the place so I took some aluminum foil and made a make shift cover for the 02 while also routing the oil where I want it to go. Once I got the drain plug off to my surprise the gear oil was runny and not thick and building up into gunk. Once all of the fluid was drained and stopped dropping I tested out pouring some fluid into the vent tube just to ensure that fluid was going into it and sure enough it was. I left the hose clamp on the hose loosened in the event that it wasn't going into the PTU and I could pull the hose and allow the oil to drain. I couldn't find a funnel small enough so I placed the bottle into the opening of the vent tube and just proceeded to squeeze. I squeezed the bottle about 4-5 times and then after waiting about 5 seconds I would see the bottle return back to shape as well as gurgling from the vent tube draining and then I would repeat the process. It took me about 15 minutes to get 16oz's in which is what was taken out.
My oil of choice this time around was Mobile 1 and will be switching out to redline on the next go around.
All in all it's a huge relief to have it done and to know that it wasn't gunked up like some other have reported and by far a lot easier than dropping the down pipes and all the other things involved with the PP just to get to the fill.
Here are some quick vids and a picture.

And then the vent tube installed and what I wiped off the magnet after running it through the fluid.
Hope this helps anyone out there!

Master cylinder. Not brake booster. Lol. Was thinking of something similar location when I had my cobras.

This will likely be the method I use as well. Thanks for the write up.

No problem at all. Glad to help the community out getting a job done easier. Like I said, I never saw and concrete proof on doing it other than the vid of the interceptor and wanted to find out for myself.

Has anyone else tried this way? If this is the new best way it really does look simpler then fighting under the car on ramps to drain and fill. Drain still might be hard but the bummer was the fill and this seems too easy?

I did this exact method. Hardest part was getting the PTU breather off of the PTU. I used my fingers. Other than that, refilling it took the most time. My fluid wasn't too bad, however the powertrain was noticeably different (smoother) with the new PTU Oil. I used Mobil 1 gear oil.

FYI- I would avoid using Mobil 1 Gear oil IMHO!!! @ 30K it was black which is normal but found a bit of sludge forming which was not a good sign! I recently changed over to Redline all around and the car seems much happier...
I would specifically stick with Redline or Amsoil especially for the PTU.. Some food for thought. Z

Good to know Z. Thank you. I have roughly 10,000 miles on my Mobil 1 "PTU" fluid. I am at 66,000 miles. At 70,000 I was going to change the RDU fluid, and since I will be there already, I will change out the Mobil 1 with Redline. Pretty sure I will just end up changing all the driveline fluids yearly.
Hope to add Amsoil SVG to this list soon

Thank you for that document SHOdded. That is great information.
I get so jealous when I see these write ups where you just have to remove the drain plug from the PTU...
How would I do this on a Non PP 2019 SHO? I'd rather not take it to a Dealership. Do the Down Pipes have to come off? I want to get this done when I hit 20K to see what I have, and may go with the catted ceramic coated down pipes to handle the heat. I still need to pass the PA state inspections....
All 2010-2019 non-PP SHOs will have the same basic drain/fill procedure. No need to remove downpipes. Follow glock-coma's writeup in the HowTo section.
I recently did this with my 2010 and it was made simple by this suction device. I did not find hardly any build up on the fill plug and emptied a entire quart of Redline Lightweight Shockproof gear oil in there, in a roundabout way doing my version of a flush....eventually it was pure redline oil coming out...let it stop dripping and put the plug back on.

I'm buying one of those to do the new car. That's a slick little vacuum pump.
Isn't that the one FordTechMakuloco recommends?
Just a couple tips to add (PP cars). With the car on jack stands, shield removed, it's easy to reach up and pull the factory vent tube off the nipple. You can also take it down off the right side stands when draining to get a little more out. If you use clear hose (cheap and easy to find on Amazon), I just measure the same amount removed and leave it in the bottle and slowly squeeze it in and burp. With the clear hose you can see it go down inside and avoid spilling when you pull the hose off. I also think it's important to burp it when going in. I'm not sure if the 10-16 oz people report going back in would put any outward stress on the seals if forced in, probably more of a peace of mind thing. Easy deal on the PP cars.

Yes it is! It's awesome, it made very fast and easy work of draining the PTU
