Currently at 56k.
A few weeks ago she started acting weird, sluggish when coasting, intermittent click when starting from a stop.
I thought I had a sticking caliper....until I smelled the propane/natural gas stench of death. No puking at all on top of the case.

I immediately changed the ptu fluid again (changed at 53k with royal purple) with amsoil severe gear.
Drove about 25 miles with zero issues pulled out of the drive and it sounded like a dryer with marbles in it.
Removed the plug to check for contaminants.
Here's what I wiped off the plug

The fluid looked like someone spilled a bottle of glitter in it. (https://uploads.tapatalk-cdn.com/20180320/a34137b5c5dc5fbac3cf754ded6407cf.jpg)
I'll be replacing myself just need to figure out which ptu revision part number has the drain and fill plug.
>.< careful where you go replaced my ptu in my 13' Taurus last fall before parking the car lol dealership had quoted me at 1850 ish and I went to the next cheapest place I found a local mechanic out of nearby town thinking I had found a good deal since it was 200$ less than the dealership.. had gotten charged 1650 with the ptu core.. ptu was 830 ish from dealer with 24k 2yr warranty ordered through that shop. While remodeling a mechanic shop/used dealership in December After letting them know how much I paid for that job I was teased a good bit. Most it would of taken them was a hour and a half. I was charged for 4 hours labor got ripped off bad.. would of payed less than 1100 at my now new mechanics shop I'll be heading to from now on.. either way lesson is careful where you go to get the job done, Best of luck!
Also don't listen to that weird BS estimate program a lot of mechanics use. Mechanic out of the local shop I had gone to was very pushy about how the program could accurately estimate almost "any job for almost any car".. too many money hungry mechanics out there..

Fortunately I do my own repair work unless it's beyond my capabilities.
This doesn't seem like it's that difficult of a job. I just want to make sure I have everything needed to complete it once I start and the most current PTU with drain plug.
I don't drive the SHO daily, so I can take my time. It's already on jack stands in the garage with kroil soaking the exhaust bolts.
Now it's time to gather parts and info so I do this right the first time.

Nice! best to save $ where you can! I guess putting Mechanic who did my ptu failed to mention me while your done there you might as well replace the cheap ptu vent tube.. need to have that done this spring before I put to many miles on the new ptu.. good luck with the job!

Sorry to see this, glock, but since you already had to have the RDU done, this is not a surprise, to be frank. the RDU is supposed to outlive the PTU by a WIDE margin, LOL.
Maybe a PTU from a 2013+ Flex would work, they have drain plugs. But I think the cooled/monitored ptus have drain plugs, so you would be getting the whole shebang. With any luck you can take off the cooling part, and fashion an adapter plate to cover the hole left behind and get on with your life.
Amsoil ONLY please. Or BND fluid like FoMoCo uses from time to time ;)

I had the ptu replaced @26 k under warranty, they couldn't find the cause for a vibration at highway speed so they just started replacing parts... so this one only had almost exactly 30k on it.
That is lifetime .. For a police interceptor LOL
Order PTU cooler kit DG1Z-7K177-A for PTU cooler repairs.
Part Number Part Description
DG1Z-7K177-A PTU Cooler Kit
The kit contains the cooler, gasket, fasteners, and instruction sheet.
So I can't find any physical difference between these 2.
The one with the fill and drain is listed for a flex,
Part number DA8Z-7251-B

This was confirmed as the most current ford part number for my vin. It does not have a drain plug.
AT4Z-7251-G

(https://uploads.tapatalk-cdn.com/20180323/5d237fe25db3b63aa20ec8160c854814.jpg)
Any idea if the 2 are compatible?
No idea, but doesn't make sense they would be different parts if the axles and seals are the same. May be just a cataloguing difference?
I ordered the AT4Z-7251-G today from Fairway ford on eBay.
I couldn't confirm the drain plug, but it's the only one I'm 100% positive it will fit the 2010
It's the lowest price I can find and still be somewhat local.
$670 shipped plus got $53 eBay bucks with their 8% promotion going on.
I was torn due the warranty from ford, you have to buy it from an "authorized ford parts distributor " to get the 2 year unlimited mileage warranty.
I found several cheaper vendors but they were not authorized distributors.
I'll update once it arrives.
good luck, hoping it works out perfect!
I would be interested in knowing if it has the drain plug as well? Its just a matter of time I am guessing before I am in the same boat! Although it would be completely awesome if you documented the process with pictures and detail write up along with your contact information and address so when I need mine done I know where to drop it off. how to do it myself!

Supposedly the newer ptu's have a full face thrust washer that prevents the bearings from walking. But I haven't confirmed that all of them get it, just the PI's
Pulled this from shoforum.
This from the current August 2016 issue of "Police Fleet Manager Magazine".
Power Takeoff Units
The power takeoff unit (PTU) has been a service concern on some PI Utilities. There may be an excessive oil smell when driving, the AWD may not work properly, or the PTU housing may be cracked, leaking or noisy. The cause of the PTU damage is the excessive torque loading of the idler gear, which causes the bearing to walk (move) into the housing.
In January 2014, a Full Face Thrust Washer, FFTW, was introduced. This new washer was designed to prevent the idler bearing from walking into the aluminum case. In October 2015, a second change was made, in this case a loose-fit idler bearing. In dynamometer tests, this bearing design change showed a twice life improvement over the FFTW design.
In June 2016, a third change was made. In this case, a new bearing design, one without drawn cups, was installed. This eliminated the walk mode of damage. Dyno testing shows a three to four times improvement over the FFTW design. For both the PI Utility and PI Sedan, the PTU is covered under the limited powertrain warranty. All Ford Police Interceptors come standard with a five-year/100,000-mile Extended Service Plan for the powertrain.
New ptu was just delivered.
Still no drain plug:( will probably end up drilling/tapping a drain @ the first fluid change.

It was packaged 1/24/18 so I have to think it's the most recent design.

Still looking for downpipes, but I'll probably start installing this late Sunday /Monday.
I would drill and tap for the drain plug before installing it on the car.
Did it come pre-filled?

It's supposed to come prefilled. I will confirm before installation.
I considered tapping before but I want to shake this new one out for a few miles to make sure it's not going to fail. Once I drill it my 2 year warranty goes out the window.
The old one is out. Half way there, still waiting on some parts so the new one won't go in for at least a few days.

Wow i should consider myself lucky then. My Ptu has fallen apart once (the rear flange loosened). Was able to buy a new flange/seal from dealer and guesstimated how tight it was supposed to be (preload). 88k and its still going but you can hear a constant whine while driving and it sounds like a supercharger when I floor it LOL.
Your PTU is for a Perf Pk SHO. OF COURSE it is supercharged!!!
A little progress today, new one is installed. Still need a flex pipe but I got all the gaskets needed in the mail today.
While I was waiting for my trans fluid to drain I decided to open up the damaged ptu....I was not expecting so much destruction.
Notice how clean the interior is, no sludge or burnt fluid.
One of the bearings completely disintegrated chewing up most of the gears.

That is some carnage! Probably a design failure that theoretically is corrected by the G revision. What was the revision on the old PTU?

The old one was revision D
according to the work order from 5/2013
Appreciate the info, kind sir!
IDK if this is new or not...if it isn't new, I wasn't aware they make a repair kit for the PTU...
Apr 11 2018 6329 - 2007-2016 Various Vehicles - All Wheel Drive (AWD) - Propane Or Natural Gas Odor During Idle Or Low Speed Driving - Built On Or Before 30-Jun-2016
Some 2007-2016 Edge/MKX/Flex/MKT/MKZ/MKS/Taurus/Police Interceptor Sedan/Explorer/Police Interceptor Utility vehicles equipped with AWD and built on or before 30-Jun-2016 may exhibit a propane or natural gas odor during idle or low speed driving. This may be due to break down of the power transfer unit (PTU) fluid caused by excessive heat. If the source of the odor is identified as originating from the PTU, an idler bearing repair kit is available to repair the PTU.
The part number for this kit is
GB5Z-7P258-A it's approx $315
I have a family member that works at a dealer, I'll see if he can order and take pics of the kit to see what's included.
I truly appreciate this very informative Topic provided by Glock-coma and hopefully you get your SHO running better than ever in no time.
Best of luck! Z :thumb:

She's back up and running, been about a week since I completed the install.
Didn't want to post to early and jinx it lol.
No leaks, but she needs an alignment again.
I had to remove the right strut/knuckle assembly.
Also tried to do a lot of heat mitigation to prevent or slow down future issues.
Wrapped the new stock down pipes and applied some
Reflective heat barrier on the ptu in strategic locations.

I'm working on gather all my part numbers and pictures
I'll attempt a "how to" but it might be awhile before I can complete it.
Noicely done, and I am sure the effort will pay off bigtime.
Nice Job! I did the same kind of thing with my truck after having long tube headers on for a few years. Trans was getting hot so I wrapped the pipes and it has solved the issue since. Looking forward to the "How to"!
