2002 TrailBlazer 2 Lo Range?

[@АндрейАфанасьев-ш4т]

It's very interesting fact. Can the transfer case NP226 work in 2LO mode mechanically?

I did a test on my own 2002 TrailBlazer where I was able to operate briefly in 2Lo. It was a fairly sketchy thing to do. If I actually wanted to safely operate in a 2Lo mode I would install a switch to disable my front axle disconnect and select 4Lo mode. Without the front axle locked I would have a viable '2Lo' operation.
