PTU, what's inside and why my 26K mi put took a dump
« on: February 20, 2020, 06:47:26 PM »
So my PTU took a dump at 26K miles,
Good reminder for everyone to regularly change fluid in your PTU.
Dealer let me keep my PTU and I cracked it open.
What I did not find inside is a bearing, one bearing was completely missing, gone, nothing left of it, gears threaded it all...

The video is awesome.  Nice to see the internals since Ford would not let me keep mine when it died at 65k.  But 25k seems super early to eat a bearing.. did it have the original fluid?  I ask because my theory is shitty manufacturing of the ptu allows contaminants into the fluid or the ptu body before its filled.. and that's why we see such a WIDE range of mileage failure for both tuned and non-tuned ptus..

:(  The PTU from 2010 to 2012 is as bad as the dry DSG... yet no recall or free coverage.  Super pissed at ford still ..

It was original, then I changed it twice once I started noticing the smell, it died 1K miles after my two changed, I guess they did not save it, distraction was already in action.
Now, my theory is excessive idling time. I purchased the car from private party and he would have car idle all the time, allot, every time I come see the car, he had it just idling as he parks. But thats just my thoughts, also it is possible that they maybe under filled by the factory, because first change I was able to only get 12oz out of it, it's ether got overheated and evaporated or under filled.
But anyway, ford should have the drain plug on ALL OF THEM and add that to maintenance schedule every 25K miles, problem solved...

25K in 6 years.  Dunno what kind of life it lived.  But I still maintain that 2013+ PTUs have had an apparently higher failure rate than 2010-2012.

Typically  the units I've seen that failed at work (X SPORTS) have a lot more gear damage and the fluid is more like tar (I know you've  changed yours). I'm  more prone to think yours failed  from torque  but that's  pure speculation.  And you're  right, heat is the devil and that's  one + on the PP unit. Next time I'm under mine I need to see where the delta's on the belly  pan line up, probably a simple  fab to get more air flow around  it. I thought I'd  seen it posted about the case flexing under high torque conditions but not much we can do about that. Thanks for showing the guys a look inside, not much to them.

I had my PTU fail before all the mods, right after I got the car and had chance to do anything to it, so it's not the over power for sure, it was stock..

I also have bottom undercarriage plastic panel removed for better air flow

Nicely done!!!! Very well articulated and great video on how to maintain the PTU! The SHOís with the Performance Package has the drain plug on the bottom which is nice for sure. If you search around, you will see a lot of pictures of that bearing your missing completely disintegrated.

Side note: They changed the design on the 2016+ MY PTUís to prevent that bearing from being eaten. And thus far, you see a lot less PTUís being replaced. This information was provided by Jessica Livernois (no affiliation with LMS) who is a senior ford tech who deals specifically with these.

I heard about new PTU revision and I was talking to the ford dealer when they were ordering me a replacement, they told me that new PTU I got installed is newest revision, so I should be good.

Are the newer builds compatible with previous gen Sho's?  Probably should just order one now to replace the one that will blow up in 50k

yes, just have to get the right one for your SHO.  2010-12 are all the same.  2013+ two different versions - nonPP an PP.

This actually brings up a question I've been mulling over since I know my ptu is on its last leg.
1. Will a 2013 pp ptu fit a 2013 non pp car? Obviously there are some lines, etc, but size wise are they the same.

2. Will a 2016+ unit fit into a 2013?
