Another addition to the tech info here. Enjoy. Hope this helps someone to get a little dirty and DIY something.
This video shows how the transfer case is serviced on 2021+ GM SUV's. As far as i can tell, Yukon's and Tahoe/Suburbans either come with the 2-speed NQH transfer case, or the 1-speed NP0 transfer case. They are basically the same, just the NP0 lacks 4LO capability. They have the same fluid capacity, same fluid type (Dexron VI ATF) and overall look the same. I don't know if Escalade V's that are equipped with full time AWD share the same t-case. If someone knows, please chime in. Otherwise, the process should undoubtedly be the same on those vehicles as well, since they already share the rest of the powertrain.
