The transfer case under the Titan and Frontier/Xterra/Pathfinder is a TX15 - which is an electronically actuated chain driven case with a 2.6:1 crawl ratio.
Older Nissans use the TX10 which is a manually actuated chain driven case, also with a 2.6:1 gear ratio.
The TX15 is an evolution of a TX10, and is actually (sadly) the strongest part of the drivetrain in the D40/etc
They are homegrown (eg, not new process or anything like that)
