transfercase diagram

[AnthonyD1978]

My experience with the 44-44 clutch is that once it's engaged and has static friction, it's locked until it's released. When I first installed the switch @Brandon-w makes I was shocked at how hard that clutch actually holds compared to how weak it was with the factory programming. In 4Low I could spin the rear tires without the front wheels engaging if I did it before the module engaged the clutch. With the switch on and the clutches fully engaged and the ball/ramp engaged, my truck with spin all 4 tires with ease in 4Low. Pretty impressive for a clutch based tcase.

As I've said before I don't feel the 44-44 itself is the problem, it's the FCA programming that kills these tcases with all the engagement/disengament. The static friction of the clutches in these tcases is pretty impressive.

I hope that's the case with the 48-11 as well.

I'm not impressed with the 44-44 and FCA programing was/is almost criminal as far as I am concerned.
When the programing takes it clear out of 4wd when you put it in park, I have had mine take off backwards twice because of that.
Now with Brandons switch install when I stop in a slippery spot I have the switch turned on and I leave the truck in drive with the parking brake on,what a work around.
With Brandon's switch the electric part of the clutch has enough torque that you can gently ease the truck to get started on very low traction surfaces. Be it wet grass,ice or packed snow.
The factory setup is just about completely worthless especially if the rear wheels have no or very little traction, without traction on the rear there is nothing to drive the ball and ramp which will provide power above what the electric clutch does.
I have a feeling that my clutches are very worn but how do you proof that to FCA.
One thing is I have never gotten an over heat light. Where this transfer case has failed me completely was in my driveway in the winter,
when this fancy RAM 1500 couldn't make it upthe drive after my wife's all wheel drive Equinox had just driven right up.
In the summer on halfway decent traction surfaces where the ball can work into the ramp and load the clutch it does work good.

Yeah I agree the FCA programming is asinine. I purposely tried the 4Lock on beach sand and it was essentially useless. The rear wheels dug in QUICK before the front wheels even moved. I mean talk about a dangerous setup if you get stuck.

Again, flicked Brandon's switch and it locked right up and pulled the truck right out. Totally FCAs Nerf programming.

I honestly feel like most of the issues would be solved if traction control was completely disabled in any 4WD mode, by default and not turned back on until you go back to 2WD.

Can we refresh this thread? I understand Brandon has come up with working solution with harness, which is great!
I would like to go a bit further and implement time delay (goes off after 10-15 min). And trying figure out the way how to use one of the oem switches under HVAC control. I already have few I think good ideas.

It looks like all of the diagram and schematics have been removed here, purposely, i am assuming.

Yes these have been removed so the system cannot be duplicated. I worked hard to get this product to where it is and don't wish to give it away, hence the patent process.

All of the ideas have been pushed forward in other threads and everyone said a timed switch would be more of a pain than anything this is why it hasn't been done.

I totally understand your point, You got It all figured out. But That should not stop other DIY people to create their own versions, isn’t.
Well I did, anyway.
I mean there is a lot of DYI project out there that people don’t have a problem to share.
My post was more like checking if anyone what to make their own Harness. That’s all...

Mean if you Wana make your own diy please feel free to do so. But please don't make it public knowledge everywhere is what I'm kinda getting at. That part scares me as I'm already a small niche market. If everyone starts sharing wiring details and everything I can basically kiss my product goodbye if that makes sense.

Not quite getting that, what’s making this project special? That’s what any car forum for, share info and discussions. Helping each other.
I am sure some people rather diy if they can, instead of paying dealer, shop or You for that matter.

You are correct, you just don't get it!
Brandon developed a product and sells it to whoever needs it. If you want to make one do it, but don't badmouth Brandon for not helping you copy his product. No businessman would help someone steal their product. Your attitude will get you nothing.
