Sorry, but you still have not explained how my transmission "limits" me from downshifting. Whether yours does or not is irrelevant. I did not say yours could, would, or shouldn't downshift. When I hit the button it downshifts, how is that limited? I imagine people are tired of you avoiding the question and me asking it, so I give up.

With the exception of 2, however. From a stop, it will start in 2 if that range is selected. It is to reduce torque and improve traction on slick roads. My '05 4 spd had the same feature. Seems needless since the truck has traction and stability control, too -- it will limit wheel spin on ice in 1st gear -- but that is the feature.

Have you actually driven a late model GM 6-speed. Mine has yet to refuse to downshift. What "limit" is that?

What is different about the GM transmission? My 2500HD seems to operate exactly the same way when M5 is selected. I do tap down to M4 if I see a particularly steep hill coming up. When you say you lock it in 5th, do you mean is will "never" downshift? Even with WOT on a 6% grade?

Funny, mine downshifts with a tap. I often anticipate the extra power needed to climb a hill and tap it down a gear to save the transmission from doing it for me half way up the hill.
Of course it does, if you are in a gear above the gear you tapped down into. If you are in 6th, and you select 5, it will force the downshift. But if you are in 4th and you select 5, it probably will not do anything.
Basically, the same as the old 1-2-3-D setup. If you have it in 3, it will shift thru gears 1, 2 and 3, but will not shift into 4th (or od or D or whatever you want to call it). It is simply less cumbersome to have a button to select range rather than have 6 individual positions for the gear shift lever.
The operation is quite different from an auto with true manual shifting capability, such as my Subuaru or the Acura TL we used to have. In my Subaru, if I select 3, it will will stay in 3 unless I let the speed get to where it cannot physically maintain the gear. I can stand on the gas, and it will not downshift. In my '10 Suburban, if I select 3 and step on the gas, it will downshift to whatever gear it needs to respond to my request.
My point is that it does a little more than control upshifting. It will downshift on command. One can use a hundred words to say otherwise, but mine does both, limit upshifting and force downshifting. Both features are nice to have sometimes. I am NOT comparing it to a true manual transmission. Drove plenty of those.
