That's unusual. At 10 ounces, you're only at 55 percent of what the manual calls for. That'd make me a little uneasy. Are you in a position to somehow rotate the wheels/drive axles, to see if you can turn the gearsets, and maybe "burp" any air out of the case?
I'd still consider running a flush cycle, considering how well renowned these cases are for sludging.

How many miles are on this fluid? 3 ounces? That's insane.
Certainly a possibility that it is heavy sludged. I can't think of anything else to try, other than to fill it as much as possible, run it for a hundred or two hundred miles, and then attempt to drain again.
If it really is that bad, it may take a few drains and refills to flush it out.

I managed to get 8 ounces out of it. Maybe 9 with what in the hose. I put a camera in and looked around.  It was bone dry after the 8 ounces i pulled out.

I managed to get 10 ounces in. So idk where the other 8 ounces are supposed to go. Manual says 18 ounces.

My car is at 21,xxx right now. Sludge was thick on the cap as well.

This might be a silly question, but if yours is a PP car how were you able to access the fill plug without removing the down pipe?

My car is not a PP. In my sig I have -PP. Which I guess is not the correct way to put it lol. "-" as in minus.  Maybe in my head it looked right.

I put the plug back in after letting it sit for 30 min at exactly level. Measured the hight from the ground on both sides of the car to get it there. I did not however spin the wheels but when I looked in with the camera it doesn't look as if air could catch on Anything.

After a test drive I will reluctantly pull the plug and see how it looks.

Can you record the video?

I can but I didn't. I was in a hurry under the car to just get it over with. I can get some next time I pull it open.

The most i can get out of this thing is like 3 ounces..... wheres it all hiding at....

I assume it just turned into a paste and its sticking to the walls.

This is exactly what I experienced and why I felt compelled to say something about it. I suppose Ford's idea of "lifetime" is 36 months/36,000 miles, in the manual it states the fluid should be changed for vehicles over in the Middle East doing sand driving every 20,000 miles. Most of us should average between 10-20,000 miles a year so that's where my recommendation of an annual fluid change arose from.

All you need is a good brand, Royal Purple or AMS Oil, etc. at around $20 which can be found locally (Royal Purple at least).

If the fluid is that sludgy, and you do not get a sufficient quantity out, you should
a) do repeated flushes with fresh fluid till it all comes out (maybe 2-3 times), or
c) repeat the drain & fill at shorter intervals till you start getting full volume out, or
b) run some solvent like kerosene (not too much of course; saw this done over on the Edge forum)

What kind of pump were you using, wasinger?

I'm going to check back in 50 miles and see how everything looks. I'll pull a little oil and use my camera to see if it is any cleaner. If nessasary I'll use a compressed air solvent sprayer to clean it out.

Here is what I used to remove the oil.

Just drove the car.  First thing I noticed is how much quieter it is in reverse. Before I could hear a mechanical gear like noise. Now it's silent. Feels smoother in drive now as well. I'm impressed.

Did you go WOT yet on the new fluid?

Hah I had to resist. I didn't want anything to grenade on me. I'm going to check the fluid level again then go out and play.

Your making it sound like this was a fairly easy project?  How would u rate the difficulty and how long did it take?

The only thing that's hard about it is getting your hands in the right place. It's a tight spot. The plug is easy to deal with. Just the process of getting the fluid out is time consuming. It took me about an hour.

Any reviews on the performance after this yet? Smoother maybe?

Not huge by any means. Just feels quicker in a wot shift. Mostly the first 2 gears. Most likely since awd is in use.
