Very good video explaining what's going on in the PTU. Only significant difference in our platform is the idler gear that sits in between the ring gear and pinion gear inside the PTU. It's this idler gear, or more specifically the bearing for that idler gear, that has been the culprit for many of the PTU failures. Hence, the many attempts by Ford to implement updates to it. The most recent iteration, combined with regular fluid changes, can drastically mitigate PTU failures, even at higher power output levels, in my opinion.

Thanks again for that great video!
Yeah I like that video. I also looked at the GM version of the PTU using the same transmission. They don't have idler gear problems they have pinion gear problems. Again insufficient lubrication in the case for GM.

Trust me, I worked in aerospace as a CNC Programmer along the holier-than-thou "injuneers" half of whom couldn't even perform basic maintenance on their own vehicles let alone do my job. It's nothing to hang your hat on, that's for sure. Maybe the fact that I was making 25% more than say someone with 5-10 years experience working 45 hrs. per week than they were making salaried at 40 hrs. a week had something to do with their butt-hurtedness that led to their defense mechanism of douchebaggery. And 90% of them all are working in Corporate America anyways which just means they're usually incompetent but are super duper good at tossing their bosses salad all the way up the company ladder. That job was my second and last job in Corporate America. I'll collect beer cans out of the ditch before I go back. Can you tell I don't miss it?

I really don't get what the big hang up on our PTU's is? We all know they suck and we all know what needs to be done to keep them alive.... run quality oil and change it often. I'm still convinced the worst thing for them is low speed/idling in high heat weather where the oil is simply cooked by the converter. Is anyone with a wrapped catless downpipe seeing the oil burnt all to hell? Has anyone blew out a low mileage one from power alone? It's my understanding that the clutch limits the torque to the rear end so your PTU theoretically doesn't even see more torque over stock anyways. If only our POS transmissions were given as much thought and time....
