So in the past couple of months I have had a burning oil smell coming in through the vents. Put the car on ramps, saw some oil coming from what looked to be the fitting on the bottom of the rear turbo (the on closest to the firewall). Took it to the dealer, told them what I found, and to fix it. So a week went by, I get the car back (With an extra wrench they left under the hood) and all seems well. Take the car to work, and down the strip a few times. Smell comes back. Put the car back up on the ramps, see more oil.
OK, maybe they fixed the leak, and just neglected to clean the oil. I cleaned it off, and sure enough the oil returned. Since the leak was small, I figured I would drive it and strip it a few more times. So last Saturday, I took the car in to fix the leak, and now to fix the defroster on the passenger side (which did not work during our last storm) and still no heat on the passenger side. My service adviser calls me on Monday to ask why my car was being worked on in the trans shop (like I would know). I said I did not know, I did not put it there. :doh:
I drop off the rental they gave me (2014 Explorer Limited 4wd---Gas hog) and pick up my car. While reading the receipt here is what they wrote "PTU unit fail condition, Code D01 7003B. Ck for trans leaks, found massive black fluid leaking from PTU unit, inspect oil in PTU unit, found excessive metal contamination in PTU. Removed and replaced PRU unit.......'
They also replaced the door actuator door that was clicking when starting and when I switch to recirc/fresh air. But now not only does my wifes side of the car not have heat, I don't either, unless I crank it up to 90. Looks like another service call.
Man, that stinks. I hope you get your heat back! I wonder what that metal contamination in PTU is. gear grindings? I hope that leak problem is over with.
Yeah I am going to hold off on racing for a couple weeks to make sure the leak is gone. I would assume they are the gears also. I don't know what is inside the PTU that would cause it. But I had no indication of anything wrong with the PTU, none whatsoever. But they also did some reprogramming and my Strategy code changed, so I am waiting on updates from Livernois.
Kinda wondering if the racing contributed/caused this.
I'm sure it didn't help. :clown: Interesting about them changing codes on you. I wonder why and what the change will mean. Too bad you have to wait for tunes again!
It is running pretty good. Almost didnt notice it was not tuned, almost. But is way better than that 6200# 3.5l Explorer.
Did you check your coolant level by any chance? Topping it off might fix the low/no heat condition. But yeah, probably a good idea to let the dealer "handle" it.
Possible your SHO had one of the weaker PTU units installed. You had no shifting issues whatsoever before they replaced the PTU? Normal to have fluid leak out of the overflow vent when it is hot. But, PTU should not get that hot if the PTU fluid is in primo condition (and you are not trying to run 600 AWHP :D ). It may have been venting for some time, till it got low enough to start disintegrating.

This article supersedes TSB 08-12-3 to update the vehicle model years, vehicle line application Service Procedure and Part List.
FLUID COLOR AND DIAGNOSIS:
Automatic Transmission Fluid
Red automatic transmission fluid (ATF) is not used in the PTU itself. The RH intermediate shaft passes from the transaxle through the input hub of the PTU, where the intermediate shaft seal is located. A red ATF leak indicates fluid from the transaxle is leaking past this intermediate shaft seal contained in the PTU. Use the seal kit, which contains four pieces: the intermediate shaft seal, alignment washer, deflector, and seal protector tool. The intermediate shaft seal, alignment washer, and deflector need to be installed individually and before the seal protector tool is used.
Brown/Black Fluid Indicates a True PTU Seal Leak
Use the seal kit, which contains five pieces: the PTU cover seal, intermediate shaft seal, alignment washer, deflector and seal protector tool. The intermediate shaft seal, alignment washer, cover seal, and deflector need to be installed individually and before the seal protector tool is used. Use seal kit, which contains the PTU cover seal, intermediate shaft seal, alignment washer, and deflector. All four parts need to be installed individually.
Was it factory fill in the PTU? If so, how many miles on it?
It appears time and time again that the recommended service interval on the fluid, especially for more severe driving habits, should be considerably more frequent than Ford suggests.

Uh, this post was sarcasm right?? You have how many dragstrip launches on a drivetrain making 35% more torque than stock?? There's no free lunch, racing stresses componants, componants fail when they are over their design limits OR are repetatively taken to the limit. Why ya think Mike (4drHtRd) dumped his much stressed project car...
No matter the cause, I truly think keeping the fluid fresh would have prevented or prolonged it.
Still can't fathom the sparse fluid capacity though. Makes no sense.

Regardless of over-stress from racing, etc... it seems that sometimes these hold up and sometimes they don't... when they fail it seems like it's 50K - 60K miles. Gotta wonder, given the 100K service interval rec, if Ford is doing a little beta testing with us on what appears to be the weak link in the drive train.

Well, if this is true, then they have been beta testing since the PTU design was first introduced what, a decade ago?

OK ... let me get this clear , it is the same basic design ... I hope like hell its not the same unit .
I am sure they have made incremental changes and improvements, but it seems the basic design remains unaltered. I do believe they have been using Haldex all along, tho the relevancy of that is undetermined.

Yes, totally agree with this.
I had my PTU fluid changed at 25K and I would NEVER go more then 30K without changing it. The more I see the more I think the stress on the PTU is stressing the grease and it needs to be changed on a regular basis, much more then recommended.

I am 100% with you on the PTU service Mark. :thumb:
I swap my PTU fluid twice a year.
Regardless of miles accrued.
Once in Spring. Once in Fall.
I'm actually seriously contemplating drilling / tapping the housing, to install my own drain hole to make performing this service, a lil less of a headache.

bpd... when you service it at the intervals you use is the oil liquid enough to evacuate?... The ones Pictured here that failed looked like they were full of tar. Do you pump the fluid out? ... and does it still flow and look like oil?
Never like oil, but not anywhere near the paste like sludge pictured in this thread.
Suck it out with a pump & the viscosity appears like ummm..... what comes to mind..... like ketchup perhaps?
On the verge of turning thick, but certainly some degree of fluidity left in it.
Not sure if that makes sense? :dunno:

Thanks... Good info that helps to get it to make sense. :thumb:
Haha! Wow. Ketchup.
What are you filling back into it?
I feel like there's some room for improvement, possibly with just upgrading gear oil.
Perhaps one that is better suited or tolerated for excessive heat and heat cycles...

It looks like this will be next on my list. I may have to visit BITOG to see which available oils are most heat resistant.

Oh, so close to reloading the tune. I did not specify for which tuner I needed it for, it got sent for my SCT, not the Mycal....damn
is there a how to change the PTU oil, and a reccomended replacement oil ? Is it worth doing at home, or take tot he dealer ? I'm at 24k miles.

That is the problem . No OEM recommendations on this at all .
There is a post about installing a drain plug on the forum somewhere .
I need to find it , otherwise it needs to be siphoned out .

It looks like the 2013+ PTU has a drain plug , I'll have to check...

I also believe I can rig I PTU cooler for as well. However for straight line drag racing it my not be entirely necessary. With a brief engagement.

I found this pick a while ago for how to add I drain plug to PTU, I figure with that and the fill plug up top and a rear dif cooler system. You'd have a cooled PTU.
But I think a 2013 pp PTU retro fit is entirely do able. Just a lot of $$$$'s
I think that between 25k and 30k between changes is a good number. I go to the track 2 to 3 times a season and during the times Ive changed it, by 30k its blackened right out. More than that it turns into a thick grey paste. My first two changes I vacuumed the old stuff out. Now with closer intervals I use a manual gear oil pump and "flush out" the dark fluid until it runs clear.

Corrected link to the other forum.
We do need to verify what updates over the 2010-12 model PTU's the 13+ might have. If they have a drain plug, great, and if they have aux cooling, icing on the cake. If someone knows for sure, please post up supportive images/documentation. TIA.
Interesting find on PTU on Police interceptor version and some middle eastern PTU's that are WATER Cooled :

From what I've heard, the PTU lube is an all or nothing type of thing. It might last the lifetime of the vehicle, but if it goes overtemp just once, it's junk.
Now the statement in the MKX manual is likely targeted to the Middle East crowd, they do a lot of sand driving over there. In fact the Explorer sold in the Middle East has a water cooled PTU. But if you look up the Police Interceptor OG, it describes how the Police cars actually have an "active" monitor that basically looks for overtemp conditions and if it sees them, it puts a notice to change the PTU oil in the message center.
My limited experience has been that in normal on-road driving, you're never going to overtemp the fluid, thus a lifetime fill is reasonable. But anyone towing on hills (especially twisty hills), going to a race track or doing a lot of aggressive off-road or snow driving could get to the point where the fluid needs to be changed.
2013+ PP pkg SHO's do have the auxiliary water cooled PTU.
Lots of work to retrofit from what I understand.

Yea ... But would it be worth it ? . Any idea if the 13+ PP has a drain plug or the if the non PP 13+ has one ?
I don't know on the drain plug, but i do recall somewhere, a person having posted an image of what appeared to be a drain plug, located in/on the housing assembly of the PTU.
I saw the image, & it did appear factory.
Non PP SHO's, for 2013+ do not have the auxiliary coolers.
I.E. Auxiliary Oil, Trans, & I stand corrected......
I misspoke...... the auxiliary cooler goes to the rear diff IIRC, not the PTU as I previously advised.
I'm at work at the moment & don't have the ability to double check schematics.
Perhaps someone else can chime in, in the interim.
