Hmmm...but their all Borg Warners...#4482 or 4484. If you run the part number they're listed as cross fitment parts for nearly every GM truck made from 2003-2005; Escalades, Avalanches, Silverados, HUMMERs you name it.

I do remember the 2003-2004 H2s having a problem with the original cases cracking or something which might have attributed to your problem, but they upgraded the exterior design of the case adding extra structural fins which became standard in mid 04 or 05; and those new case (listed above) ran for 3 years (4 in the case of the H2), so they're should be a lot of them and parts around. They shouldn't be terribly 'rare' especially given how many GM trucks would have been sold during that 3-4 year period. Weird...

...well, at least you've got it all sorted now.

Yes you are probably correct because one shop did tell me I could use a tcase from a Silverado 1500, BUT when I asked if it would be sufficient for the size tires I'm running, the guy was like, "oh never mind". He said something about the belts or ??? inside the tcase would be smaller in the 1500 case vs the H2 case) therefore the addition of oversized tires would not be good . (I'm sure belts is not the correct word, but I'm sure you know what I'm talking about). So back to square one I went.

You may be on to something...the case seems to be cross platform but the inerds is likely to be different...especially when you consider that the deuce is if full-time 4WD. I'm pretty sure all the other GM trucks can drop down to 2WD.

Yes I would venture to say that's probably close to 100% accurate. I used my VIN when inquiring about a complete replacement from a company in MD as a matter of fact I think, and they were the ones that mentioned the 3 to 4 month backorder. They rebuild cores on exchange with warranties, but said my particular case per my VIN was hard to come by. Keep in mind this was not an authorized HUMMER dealer though. Just a powertrain mfg co.
