Auto 4x4


Recommended Posts

Just traded my '14 Sierra 1500 SLE for a '15 Chevy 2500 LTZ and had our first snow day. Just realized the 2500 does not have the "auto 4x4" option. Is this for all 2500s, or just the way mine was optioned out? Not a huge deal, but I used to just set the Sierra in auto for the winter

All 2500hd and 3500hd do not have auto 4x4. Most likely a torque/weight application deal (would destroy the clutches for AUTO behind a Duramax for sure). The transfer case used behind the gas was upgraded to diesel internals for either 2014 or 2015 I don't recall this very minute...real stout transfer case.

My guess is that it wasn't so much that the transfer case was upgraded for the gassers to meet Dmax needs, but that GM did the smart thing and just standardize the component across the platform. From hauling production auto parts to assembly plants for years, standardization simplifies logistics and cuts costs substantially. Less risk of sticking the wrong transfer case in during the build.

Or there is a new higher output HD gasser coming, and they just are prepping for it...

 

Hey I can hope can't I :driving:

Gas and diesel have used the exact same transfer case all along, zero difference.

It is a given that we will get a new/bigger/more powerful gas motor, the question is will it be rock solid like the 6.0 is?!?

That is the $1000 question! Considering that the majority of 3/4 and 1 ton GM pickups are primarily used by commercial buyers, if GM doesn't want to hurt their reputation with those folks, they had better put in something that has a strong durability, reliability, and longevity tested track record. It takes years and years to regain a commercial market when they get screwed. This was one of the reason, among many, that I got my 2015 2500 6.0L pickup. I was not comfortable that the future would offer something as good or better than the bullet proof 6.0L L96 motor. I don't mind a bit eating some crow and having GM put out something with more muscle that has a great reliability, but my comfort level would not let me take the chance.

Well, just got our first measurable snow this winter. We got about 6-7" in my area. I don't really miss anything about not having auto 4x4. I had to use 4x4 quite a bit during this latest event. The joys of living rural. I guess it really doesn't matter much to me about the auto 4x4 thing after all those years of having to actually get out and lock in hubs on pickups and manually engage transfer cases. The electric 4x4 engagement is a breeze. Still don't trust it as well for durability as the old style manual shift transfer cases, which I would still prefer as an option the OEM would provide, but that isn't going to happen.

I always thought that to but the fact that this 4wd system has been in use since 1988 and is proven is good enough for me.

 

I also have a '06 Super Duty Lariat and had to walk in the mud today to lock in the hubs as I was stuck, screw that, will leave them locked in till June now.

I can definitely handle the not locking in hubs. But I am still partial to a manual shifting transfer case. I just never have grown fond of electronic shifting versions, but it is the world we live in know. Just one more thing that can go wrong. Last manual shift transfer case I had was in a 2006 Jeep Liberty diesel. I don't think anyone is doing manual transfer boxes anymore now. Some things were best left alone.

Actually, you can still get a manual transfer case in the WT models...
