This doesn't apply for 2013+ PP cars.

Ok, here is a crappy photo, but you get the gist...

As you can see, the sludge is still stuck in the bottom of the Gatorade bottle, and it took awhile to slide down to the side when I took the pic. It is not as bad as some I have seen on here, but it is not good.

I have noticed a few things, and it may be in my head... but the car seems quieter overall, and as one other poster on this board said... more "free wheeling" with less resistance down hills and less throttle input needed to keep constant speed.

I am stunned!  Thanks for the pic jcl!  It certainly looks like the oil was failing.

Since the PTU was not removed for cleaning, can you describe the flush process in a little more detail...cleaning agent... number of times flushed....how much was used?

Sorry if I missed it, but what was the charge?

Sure Mac! Well, I started by sending my mechanic the write-up posted above by glock-coma (thanks glock!) and asking him if it was something he wanted to get into. He agreed, and followed the write up. Basically:

Drove the car around turns to warm up the fluid in the PTU.
Remove the fill plug.
Siphon out as much fluid as he could with a vacuum brake bleeder kit.
Pumped in redline 75W-140 until it poured out, bringing with it more sludge.
Did another siphon round, sucking out the new and old fluid.
Pumped in more until it looked much better and replaced the fill plug.

However, after all this, he recommended bringing it in in a month or so and doing the whole thing over, being that it was so bad. His reasoning is that with the new fluid in there sloshing around, it will gather more of the sludge and we can purge it again. I believe I will be doing it again.

The cost was $139, which I believe is fair for the time that he put into it, and a ton of redline 75W-140.

Many thanks jcl... 

I also think $139 is a really fair price.  (my wifes oil changes in her F250 exceed $100).

I also agree with your mechanic's advice as a bit of driving will likely loosen up more sludge that can be removed.

Clearly the maintenance on PTU oil should be done at shorter intervals... most have felt that 25K miles was the mark.... Time will tell as more of us get this done!

Wow, got me thinking I might do mine at 15,000 miles just to be anal...

How many quarts of gear oil do you need to have in order to do the flush?

Similar method to flushing cooling systems at home...

Definitely seems like the smartest flushing method, with keeping the PTU installed.

I was under my SHO last week for LOF, and I didn't spot a drain or a fill anywhere. That thing is nestled pretty far up there.
But, it was dark and I was tired.
I'm going to go back and take a look this weekend.

Looks easy to do, in regards to work space, with either the car on ramps or stands.

I thought 13+ PP featured PTU aux water cooling? It's the RDU which is cooled (oil cooler I presume?)?

So what are dealers around the country charging for this service?

Yes 2013+ PP cars, PTU has water cooler oil cooler. RDU has no cooler. From looking at drawing online of your PTU looks to have a drain plug, on the pan side of the PTU. However there doesn't appear to have a fill plug, so filling would have to be done thru drain or thru breather tube. By injecting thru opening with the appropriate amount of oil.

Should make it easier to flush the 2013+ PP, if it is even necessary.  Still need data.  Still in the dark about 2013+ non-PP, safe assumption that 2010-12 rules still apply.

[crash712us]

Yes non PP 2013+ have the same PTU as 2010-12's

A lot of them won't even do it...mine wouldn't.  Said Ford considered it a "non-serviceable" part.
