As an aside it should be noted that when operating our transmissions in the manual mode it will downshift by itself (although not down to 1st gear) or you can downshift "at will".
Just to clarify this statement, the only circumstance it will downshift is when the speed gets below ~900 RPM in the given gear, as it tries to keep the torque converter locked in "m" mode.
My wife's Sienna has a manual shifting mode, but it will downshift to the lowest possible gear at WOT no matter what you do.
The system on the Super Duty allows you to apply full power in any gear at any speed the gear can be used. I use it often to save some fuel by applying full power in 6th gear up a certain hill going home. Engine is at 1,000 RPMs and it just chugs right up without downshifting!

I agree that hill decent control works well. Almost so well that it is counterintuitive. When I engaged it at the top of the hill i had to press the go pedal to get down it. Without HDC, I would have been riding the brakes all the way or employ another strategy.
The only thing that I find operationally different between our automatic transmissions and manuals is the lack of a clutch which provides the ability to engage it and coast or up or down shift two gears at a time. I have a small commuter car that is manual for commuting and enjoy driving it in light traffic, but on Houston freeways, dense city traffic or hilly terrain, not so much.

This is just a guess but I would think that if you are coming down slope with a load you could easily keep the rig under 20 MPH by selecting any one or a combination of:
HDC
4L
Manually selecting 1st gear (utilizing engine brake as the manual does)
H/T mode with exhaust brake
4 wheel disc brakes.
It sounds like the automatic evolved leaps and bounds. I'll probably find this out when I eventualy make a trip to the dealer but i'll ask since you brrought it up, is there a limitation on how slow the truck is moving that the exhaust brake can no longer be used? Example: If i'm doing 25MPH is the exhaust brake usable?
Oh boy, another exhaust brake discussion. The short version, the Ford system is integrated with the tow/haul and it's operation is very automated. It will not perform like a "jake" brake. It works, at least in my truck, as well as I ever expected. The off road descent feature will do everything you could ever want. It is true, with this option engaged, you will need a little throttle as you descend. I think it would slide to speed up before rolling faster.

The auto transmissions have evolved in leaps and bounds and not just this year. For the last 10 years they have only gotten better almost every year. I hate to admit it, but I believe we have the Allison to thank for that.
Even the 5R110 in the 6.0s and 6.4s was superior to the ZF6, but I won't waste my breath trying to convince anybody of that. After 88,000 miles on my 6.0 and quite a few of those at 400+ hp the 5R110 never even showed a sign of weakness. It towed up to 18,000 lbs many times and for 2 years of it's life towed 10,000+ lbs at least weekly. The guys I know with ZF6s at that HP level replaced more than one clutch in less miles and still had to suffer with less performance than similarly tuned 6.0 with an auto.
Ford is providing what the market commands. If you can't live with that lucky for you there is still one manufacturer that offers a manual trans. You can bet that Ford isn't going to suffer because of that lost sale. They have already calculated their risk and know their market. It's kind of odd that the only one of the big 3 to still offer a manual is also the one that seems to be lagging behind the worst in the technology department.
My BIL works at the Louisville Assembly Plant and informed me that they are building 2011s with manual transmissions, problem is, they send all of them to Mexico. I have to wonder why they can build them for Mexicans, but not for us.

Very interesting. I wonder how we can confirm this? looks like I will be going to mexico to purchase one of their currupted, drug cartel superduties.
I went to Fords Mexico site and found that they do offer the 6.2 with the 5spd manual and the 6.7 with the 6spd manual.
Their site is difficult to navigate, partially because I only know a few key Spanish sentences that have assisted my many ventures across the border (relating to beer and bathrooms).
They have the F-250 listed with the 6.7 (which is rated at 300hp/660torque) with an automatic, the F-350 chassis with the 6.2 and 5 spd manual, and the F-450/550 chassis with the 6.7 and 6spd manual.

I am not all surprised at manual transmissions being offered outside the United States. I have employees in Europe who are amazed that we are so reliant on automatic transmissions.
I find it difficult to believe that Ford would offer the manual in the Mexico market and not here. If they went through the expense of developing it for Mexicao, why would they not offer it here. Maybe PowerstrokeHD can get us some answers.

Not sure why there and not here, but I, too, can verify that manuals are available in Mexico. I'm aware of a few hundred being upfitted in the US before shipping on to Mexico.
So if you take away the whole R&D argument and Ford already has a stick available to mate up to the 6.7, why not offer it as a special order option, even at a premium like the auto tranny used to be?
It's really disappointing to know Ford didn't discontinue the manual, they just quit offering it to Americans.
