2004 Buick Ranier CXL 4.2 Transfer Case?

[DurangoJack]

I am looking for a transfer case for my 2004 Buick Ranier CXL AWD. I want to avoid buying the wrong case, so I am hoping someone can steer me in the right direction. There is a tag on the case, but some of the lettering/numbers are hard to read, I'll give my best shot. Model 126G14 - Assy No.1258 ?0847 - Serial No. 10 20??3 3. The cases I have looked at online are tagged either NP4 or NP8, I don't see that designation anywhere on the case. I've included a picture of the tag.
Any help will be greatly appreciated.

The case model # appears to be "126GM". If so, that's an NP4. Found this link that indicates it would apply to your '04 Ranier: 126GM Transfer Case (NP4)

Np126
It's a non-selectible part time auto-engaging AWD t case
Essentially it's akin to the envoy/trailblazer np226 (select 2wd or 4wd) t case if you were to always leave it in auto 4wd mode
The 126 also does not have a low range.

A t case from an envoy or trailblazer with selectable ranges will not direct swap.

Not direct but it can be done:

You can swap an np 246 or 261 or about anything else too...won't be direct but it can be done
