I had a similar problem last year with the ptu brought it to Ford and it cost $3,500Last Sunday, our wife was driving our '16 Platinum and got the tell-tale gear oil stench. 61k miles.
She got it home and the stench was quite clearly coming from the vent tube at the top of the PTU. It smelled just like a differential that had been run completely dry.
I had already done the PTU vent hose extension, with the intent of changing the PTU fluid, but discovered I did not have any tools that could remove the drain plug. I left it alone until the next oil change.
Well, that didn't happen. I pumped 12+ oz. of Royal Purple 75w/140 down the extended vent hose. It seemed 'kind of' OK. The PTU and the output seals were dry - no leaks whatsoever! Wife drove it all this week, as I was out of town in my car on business.
However, the car didn't want to move well in reverse as of Thursday. It needed a bunch of throttle just to move, and last night it sounded like there were rocks in the transmission. Checked the PTU, and rear diff, both were completely dry outside. The transmission fluid was red, at the proper level, and did not smell of gear lube. Same for the oil level.
Limped it to the local Ford dealership and am waiting for the confirmation that the PTU is fried, expecting a $$$$ estimate later. If I get what I am expecting, I will be contacting Ford, as I am not a happy camper right now.
We had experienced the 58-68mph shudder for quite some time, and it got REALLY bad as this PTU began to fail. I suggest anyone who gets this shudder get their PTUs serviced ASAP as I believe this was a precursor symptom of the PTU on it's way out.
I'll update this thread as the story progresses.
A couple of months ago my tranny went. No reverse and only 1st and 2nd worked. Had that fixed for another $4,500 this is my 3rd explorer I absolutely loved my 2004 Eddie Bauer besides the hub bearings. I’m never buying another explorer
