Kudos to you. You are a premier driver and glorified engineer and we are all high school punks driving our dad's $60k trucks. Congratulations on your success.
There is no published information, I've said that repeatedly. What I was talking about was the conversation I had over the phone with a man named Don Hughes who was the engineer I had spoken to on 8/14/2014. I can show emails back and forth between me and 3 high ups in Ram talking about this whole thing, and the information was posted here around that time, so if you want that information you can contact ram and speak to him, or just speak to ram customer care, they said the same thing.
You didn't answer my question. Above t he old system that 4 auto, above the GM system with 4 auto, provide one advantage over those systems, the advantages of a system adding 4 auto are numerous, the advantages of this particular transfer case over those transfer cases don't exist.
Here is the email that I got from a case manager that halfway explains it.

Ok... So in 4 lock off road you would rather have a computer dictate when torque goes to the front axle than just being split? What advantage does that have? I've had my two trucks in identical situations, my 1500 overheated the transfer case because the clutch slipped, my 2500 had no issues whatsoever in the same spot with actually a little more snow with the horrible Firestone tires vs the silent armors that came on my outdoorsman that were amazing in the snow. Anything with a clutch can slip, you bring up your Durango, my wife has a grand cherokee. In normal everyday driving they are identical, but in that jeep when it goes into 4 low the front and rear are mechanically locked, the clutch gets bypassed. If ram would have used that I would be fine, because it at least allows you to keep moving and no have any slippage.Your email shows us what we already knew... torque is pushed to the front wheels of the ram based on need. Which is why some people can get spinning front tires at a stop and some can't. Putting it in 4lock on a slippery surface, letting it idle, will spin front, and back. What you've shown us is nothing short of Ram telling us how amazingly advanced the system is ( thanks ram ).
As far as what's better, the entire system is better, in every way. From the way it engages, the time in which it engages, how utterly useful it is. This is a light duty truck, with a light duty transfer case bro, what are you wanting exactly. This truck will out perform thousands of trucks off road, literally thousands. Going into the engineering marvels that were pulled off here is silly, we already know what they are.
Bottom line is, if you're getting stuck, THEN turning on 4wd, you need to learn to wheel. If you leave traction control enabled, turn on 4lock, and drive, your front,a nd rear axles will lock at the same speed, just as designed. That's ALL that matters here, the ins and outs of exactly how they do that are moot. What you're expecting, and from what i gather, many of you expect, is when you put it into 4lock, you expect to be able to WOT the thing, and all 4 wheels start spinning to pull you and push you through whatever you've managed to put yourself in.
That... DOES Happen. If you're sitting in 18 inches of snow, just spinning tires, then you NEED TO GET A DIFFERENT TRUCK. It'll overheat with a chain drive too. You can tell me about how your 1999 bronco, or whatever car you had before doesn't, that's all well and dandy. Times cahnge, things change, THIS has changed. I knew -exactly- how my truck would perform offroad. I looked for the bw44-44, i wanted the 4auto. It's a superior tcase over the lower trimmed bw44-45. It's just the way it is. It's superior due to 4auto, just because you don't need it, don't like it, or think it's stupid, doesn't mean it's changing. It has more functionality, costs more to make, and does more. With that said, you haven't the slightest idea what the torque management system on those clutches are, you will google, and you will come up empty handed, but you have no idea. i suggest you accept that what you have is what you have, and learn to use it to your advantage.
On a serious, no douche note. Watch some youtube videos of higher trim trucks off road, the tcase DOES perform well, it just does man. I have to use the same opinions on myself. Just because I THINK it does good, doesn't change the fact it won't for some others. But looking through some of the replies ( no offense to you ), you have people talking about spinning tires and etc etc etc, the system is deisgned to be used with traction control on, just bceause it's more FUN, and gives you more control with it off, doesn't mean that's how it's designed. You won't get wheel spin with fresh powder in 4wd, EVEN rear wheel spin.
I'll leave it on this note, because that's just all facts, I'm sorry we don't see eye to eye, I get your passionate, and you are pissed off. Just because I feel a certain way, doesn't negate your anger, in any way shape or form. I really am sorry you have something you don't like, that's a **** load of money to spend, research or not, you spent it, and now you're stuck with it. From one human to another human, that's just wrong, even if nothing Is wrong
Read the email, it gets varied depending on what the ecu wants.
Where does it say that? In all modes it does the same thing.
The explanation straight from engineering is a lot more precise than they will tell the general public. Stuff gets misprinted all the time in manuals and sometimes gets corrected and sometimes doesn't.
I know when I drive in 4 lock, I can definitely feel the difference from 4 auto.
It's not really a perception as experience for me. I've never seen a torn down subaru center diff before, but I test Audi diffs at work and they are helical gears transferring the torque just like in the rear axle in the HD's, there are no clutches involved so nothing to really "slip" or wear out.
My truck there was no difference. In those videos there was no difference. Either way on a dry parking lot there isn't any binding in any mode.
The engineer explained the general functionally. He didn't go into detail about the different modes, such as 4 auto vs 4 lock.
