"How-To" PTU Fluid Exchange - glock-coma

Trying to clarify the amount that should go in PTU.  I've seen 11oz, 18oz, and just fill till it comes out.    Is 18oz essentially just filling to the hole?  Thanks for the help.

The fluid capacity of the PTU is 18 oz.  No telling how much is actually in there.  So fill it till it just starts coming out of the fill hole.

18 oz is the capacity when dry. Depending on how you are extracting old fluid, you may not get every last drop out.

The fill hole (or temp sensor port on cooled PTUs) is your true "full" mark.

With vehicle LEVEL, add fluid until it runs out of the fill hole, that is the correct level.

EDIT: Manu beat me to the punch by just a few seconds. LOL

Hello all new here but I had a quick question. I just got a Explorer sport with 44,000 mile 2014. I want to change the pdu oil. I'm a big believer in amsoil and wonder if anyone else tried it. It's my understanding it's 75 145 gear oil just wonder if this is OK to do or does Ford oil have some special additive that's required

I would honestly say Amsoil & Redline to be far superior than any other brands on the market.IMHO.and your XSport will indeed thank you later and due setup an intro for yourself simply by following the below link and welcome.  Z

Amsoil 75W-140 Severe Gear is what I put in my PTU @ 30,000 mi.

A change now is a good idea. :)

Amsoil is top quality stuff.  Can't go wrong with anything they sell.

I use Royal Purple for the PTU and have been happy with it.  Just another option since the Amsoil isn't as easy to find.

No special additives needed.  Just use 75w140.

^^ One of my best friends. Happy to have him join us! I love his black Explorer Sport!
 
All the pics just broke in this first post for the howto, any chance of having them hosted somewhere else, or does anyone have a copy of that post PDF printed with the pics embedded?
 
Yeah, they want to charge $400/yr just for hosting a few measly pics.  Nincompoops.  I guess I will have to move the pics somewhere else or figure out how to post them inline in attachment format.
 
I'm pretty sure I  can still access these or even might have them in my phone. I can  re-download them through the Tapatalk app if needed.
 
I actually relinked them from the attachments in the new post above.  Works out ok.  May create a thread with attached images instead and use for linking, as the broken links are discovered and repaired.
 
With regard to the question of whether or not to change the PTU oil and what it looked like, when I changed mine at 100K (I put in a drain plug), it was disgusting looking - thick, gooey and black and nothing like what would have gone in. I changed it about 6 times in a 2 week period and once flushed it with tranny fluid as a cleaning agent to get more of the goo out. After that when I changed at about 15K intervals it is much cleaner than it was at the initial change and no issues with the PTU at 160K.

As far as whether or not is it necessary, a friend once said "it's cheaper to change oil than parts" and since the oil was as bad as it was, a PTU oil change is cheap insurance regardless of Ford's recommendation of it being a lifetime fill. It did last through the warranty period and that is Ford's concern. As many others have surmised, I also think that since it is so close to the exhaust, this of course doesn't help the oil life. What is the downside to a PTU oil change - $20 now that I have a drain and I do it myself.
 
i wonder if adding a drain would actually raise the risk of failure by weakening the case....maybe it doesnt make much difference, but ya gotta wonder.
 
Probably caused from using a breaker bar to tighten up a bolt or the drain plug!
Sometimes doing something gently is way better than "bigger is better".
And they make torque wrenches for a reason. I change a water pump on my Envoy recently and since the bolts were going into an aluminum block all recommendations were to follow the torque specs which were very low so the bolts wouldn't strip the threads out. The PTU case is aluminum so overtightening the drain plug, if it's steel, could cause splits in the surrounding case.
