Looking pretty darn good!
Other than a couple typos, here is some information you might want:

The NP231 has an aluminum case and it should have a tag on the back saying New Process Gear, Model 231. New versions of the NP231 are refered to as NVG231 or NV231 which stands for New Venture Gear. The tag on the back of the transfer case will reflect the name change. Only the name is different. A NV231 HD model is used in some ZJs. Presumably this is a "heavy duty" version for Jeeps with the big V8s.

Usage
Since 1988, the NP231 has been the "Command Trac" transfer case used in Cherokees (XJ), Comanches (MJ), and Wranglers (YJ). It has been the "Command Trac" transfer case in the Grand Cherokee (ZJ) since its introduction.

Also, I believe the 5.9L was available starting in 2002 for the Overland.

Thanks for the feedback, I made a few corrections. I just want to get some sort of confirmation from Moabster that he can make this sticky for us. How about it?

looks good and also a good idea. i would add, under the updates, where you listed engines changes about the 5.9 being available only in 98. i know you mentioned it later but thought it should go there too

I went ahead and put that in. Im going to PM Moabster and see if he will make it sticky, after I give him the final draft.

93-94 V8 ZJ's could have the NP242 Selec-Trac t-case.

Also in 93-94 (not sure about 95) NP231 Command Trac was available with the I6's in SE's and Laredo's.

The Dana44A was introduced on V8 models (mandatory) midway through the 95 model year. The Dana 35C was available with a 3.73 ratio and LSD with the tow package previous to that, or with I6's after 95.
