The name of the transfer case is usually on plate attached to the shifter
bezel. There are others, I haven't uploaded them recently.

For general intents and purposes* the part time of the Command Trac (nv231)
and the part time of the SelecTrac (nv242) is the same.

*The part time on the nv231 is a bit superior in limited applications, my
opinion is I would rather have the ability to have a true 4WD anytime than
the slight off-road edge. (I've had both TCs)

The differences were described in another post but I will add that the nv242
(SelecTrac) is a true 4WD, the nv249 (and later 147 and 247s) are AWD where
the majority of power goes to the rear wheels and power is sent to the front
when the vehicles wants to.... you really have limited control.

With the nv242 you select 2WD or 4WD yourself. In addition the transfer
case is gear and chain driven not the gerorotator pumps and clutches

I had a '96 ZJ for a long while and was very happy with it. It needed
no repairs that were out of the ordinary for a Jeep (radiator, fuel
pump, sway bar links).

Mine had all the scary options that people complain about:

Full time 4wd: Never had a problem.
Aluminum Dana 44: Never had a problem (and I towed with it a lot).
Automatic Trans: Never had a problem (and I towed with it a lot, but I
installed a shift kit).
All power options: Almost never had a problem - driver seat heater
quit and the memory mirrors were funky.

If you get a ZJ, get a V8. The mileage and reliability is the same as
the I6 but it has much more power. With the tires at max inflation, I
could hit 22mpg on the highway. Average mileage was 18-20. I'd also
recommend a Limited over a Laredo since the used prices are nearly the
same and you get more gizmos to play with.

One problem with the ZJ is the auto climate controls and associated
stuff...if that ever goes out, the labor costs are horrid. Some folks
never have trouble, some do.

The ZJ is more aero than the YJ, but kinda like comparing s sloped brick
to a brick. I've never gotten as bad as 12 mpg unless I am offroad in
lower range for long. Around town with fairly moderate hotrodding I get
in the 14 range. This is on streets and mixed expressways where you can
run it up to 45-50 and get the torque converter locked up nicely. For
freeway cruising at speeds from 65-80, I get about 20-22 depending on
gas brand, heat, and time of year [lower in winter]. Only non-factory
mod is a cat back.

Except as the speed goes up the better body shape of the ZJ helps. A
bit. The ZJ is pretty light as well.

Depends on what you plan to do with it.
You can get the part time 4 wheel drive which is arguably better for
mileage and still available when you need it. This one has 2 hi, 4 hi,
4lo positions. Or you can get the full time which has only 4 high and 4
low. I get the 14-22 mpg with the full time.

The ZJ can be turned into a good dual use machine, put some Edelbrock or
Ranch adjustables on it and you have a fairly decent highway machine
that still can go offroad to a good portion of the trails that the more
capable wranglers can go--and get back to the road at the end.
