Question about the auto 4WD

[Jason_S]

The NP242 has 2wd, 4wd full time (awd), 4wd HI, 4wd Lo and Neutral.

I am not 100% on what it had, but if the selector was manual and had those 5 positions, then it was a 242. I know a few of the Durangos around that time period, 99-01 IIRC, came with it. If it did not have the 242 or an electrically shifted variant (I forget the number), but still had an AWD mode, then it is probable that it functioned similar to the system in our GMs.

There are a ton of different transfer cases from NP ( New Process) and BW (Borg-Warner) that came in many different configurations and ratings. Chrysler seems to have a preference for the NP units while GM seems to have developed a preference for the BW units.

Interesting knowledge. The 2001 limited model that I owned before my Denali a year and a half ago had 2WD, 4hi,and 4lo on the electronic selector. And then this past winter while the Denali was down and I had the R/T 5.9 Durango loaned to me, that one had three selections as well but it was AWD, 4hi and 4lo. there was no 2WD option on that one. That's why I assumed it was similar to the auto-4 on the GM full sizes that the OP was referring to.
