I would like to know the specs and settings for the NV133 electronically controlled transfer case, out of an '03 Durango. I have read the FAQ, not much help in terms of breaking down models or anything. Thanks.

 

Well, the 1xx means it is a 1 speed transfer case, so there is no low range. The x3x is it's size and strength rating... same size and strength rating as the np231. The xx3 means its a part time electronically shifted case.
