Oil Change and PTU Change and MORE

[SHO-Pa]

holy crap

Yup. That's pretty much what my plug looked like too. Its almost like the gear lube becomes a gooey grease rather than a flowing lubricant.

I did mine in Oct following the posted procedure (car has about 90K then).  It was not too bad a process - the car was on a lift.  Did the rear diff also.  Did not save samples.  Put Mobile 1 fully synthetic in as replacement.  As I recall I could only evacuate (using an electric sump vacuum) about 8-10 oz from the PTU, this is about half the of capacity stated in the 2010 Service Manual but I owe it to maybe not hitting the lowest point in the transfer case with the evacuation tubing.  The stuff I got out SMELLED terrible!  Story I've pickup up from these forums is this is due to lube used during assy.  I'm sure the mobile one is doing well.  I'll be watching for more results and will likely undertake this again in the spring.

I'm going to try to service the Explorer before 36k and upgrade the fluids...
I will send off samples ( If I dont  forget)

^Good info, integrity.

I won't have time this year, but hopefully at least this spring I intend to dig into my PP equipped '13 SHO and figure out how to get that damn pudding out of there. And you can bet I'll be sending that off for UOA. By this spring, I'll probably be sitting right around 20K miles.

The drain plug is magnetized so it will hold onto tiny metal particles.  I would not be alarmed by what looks like goo on the drain plug.  Automatic transmissions often have a magnet in the pan and they often look horrible while the rest of the transmission looks clean.

My PTU drain plug looked similar to the one in the picture but I sucked out about 10-12 ounces of lube and it actually looked very good after 50,000 miles and poured easily.  Gear lube will be black and it will stink after a relatively short  time.
