Thanks for all the thoughts and opinions. But I'm still don't understand why the official manufacturer maintenance schedule does not mention changing the differential fluid. How does the fluid go "bad"? It's a very heavy oil. A few metal filings in the sump won't hurt anything, and it's not as if there are combustion gases to contaminate it.

What you can do is unplug it and insert a smaller hose into the tube center and clamped it down to make sure it doesn't spew out. Have someone start your car and as the fluid is pushed thru the smaller hose, pour the new fluid into the reservoir. Once the fluid becomes clear (within 5-10 seconds) like the new one, stop the engine, reconnect the hose to the reservoir and you're done. Be sure to plug the hole where you unplugged the hose, otherwise you'll have fluid all over the engine bay. It took about 10 minutes to figure out, and since I'm hardly mechanically inclined and a lightweight in this dept., it should hopefully be easier for you.
One thing to consider-- once the liquid is clear, stop pouring fluid into the reservoir and let it almost reach empty, then stop the engine (it will take 1-2 seconds max). By doing so, you can keep from losing all your fluid when you reconnect the hose to the reservoir.
Good luck!

"Visually inspect for signs of leakage at specified intervals. If towing a trailer, using a camper or car–top carrier, or driving on rough or muddy roads, replace the transmission fluid/oil at every 30,000 miles or 24 months."

Lots of opinions on this, but it's generally agreed that synthetic is better than OEM. Mustang uses Mobil 1, I use Amsoil. If you're changing it regularly (30K or so), it's not really going to matter which synth you use.
Sweet, a decent puma. I've just got a couple of monster-sized Maine Coon types. Don't have the ***** to go exoticat.
I've seen the screw on type pumps since my swap, so I'll go that route next time.

Actually, it's a little more complex. It only says to change it under very specific circumstances. Otherwise, you're only supposed to inspect for leaks.
"Visually inspect for signs of leakage at specified intervals. If towing a trailer, using a camper or car–top carrier, or driving on rough or muddy roads, replace the transmission fluid/oil at every 30,000 miles or 24 months."
