Transfercase help!

[1978chevy4x4]

I have an 02 Bravada that has np 126 transfer case. 4x4 not working. Narrowed the problem down to the clutches being smoked or the solenoid that engages them. I can't find much info or even kits for this transfer case so I came te best place I could think of so any help would be much appreciated.

I posted this in another thread you posted in, but I'll put it here since you started this one and will be more likely to see replies.

The manuals are available here - http://gmtnation.com/f23/need-service-manuals-get-them-here-371/. It's a sticky in the Technical section.

On the offroad site a couple of us started the month after Vertical Scope bought trailvoy (and I saw how deep the ravine was that it was going to head into), we have a great theory of operation article on the NP226 transfer case. Just ignore the parts about the LO range.

Offroadtb.com Transfer Case Operation: NVG 226 (NP8)

There aren't any solenoids like an auto transmission, just an encoder motor on the side that turns a shaft to engage the clutches. Being dealer-only parts, I've never heard of aftermarket rebuild kits for the clutches. Rockauto has reman units for $727 and various bearings available, but junkyards and Ebay will probably be cheaper for a whole assembly.

GM Parts - Chevrolet Parts, Cadillac Parts, GMC Parts and Buick Parts powered by Nalley Buick GMC Brunswick | Nalley Buick GMC Brunswick has the following exploded parts views, and all the individual parts listed for purchase EXCEPT the clutch disks! Items 13/14. I never noticed this before. Inconceivable! Sorry, but I don't know of any member who's ever rebuilt an NP126 or 226 to the clutch plate level.

In a quick search to help you get started, I *did* find a site that lists clutch plates for NP126, so they're out there somewhere: http://www.wittrans.com
