Haha, I wasn't shopping for t-case fluid at the time, but that caught my eye walking by. Had to order the XL12 when it came time.
Ford discontinued Mercon, what,- back in 01/02 there abouts..Valvoline and others carried on the formulation until Motorcraft finally came up with XL12. For the T-case in these trucks, that's what you need. Curtains for sure, probably sooner than your average Merc V fail lol...that stuff eats the T-cases in these trucks.. further, taps the wallet before that one is all said and done lol.

Smarter than most Racoons
Lower viscosity usually means a weaker film strength which is fine for machines built for that viscosity, but may not provide the proper lubricity when needed. And higher temps. will aggravate the problem as the film strength will weaken further at higher temp.

Since this is the ONLY fluid I haven’t changed I’m going to do this in the Spring.....with Mercon V 
.
This looks like the best way. I like it better than using the motor to drive the pump.

I have an 06F-150, and I switched to Mobil 1 ATF, as I was having noise issues/stiffness when very cold in the winter. This stopped the noise issues and I change it out about every 3-4 yrs with new fluid. No problems since using it

Hey all - can I use Mercon V ATF for 2009 4.6L power steering? I've researched a bit and am confused if ATF is okay for power steering. I already have a quart of Mercon V ATF, but there's no power steering fluid designation. Thanks for any help

I've used the motor method as well, but you have to be real careful and slow doing so. Very easy to suck dry, if that occurs during the process the pump may never be the same again. You can screw them up that quick.
