You should have the 207 Command-Trac transfer case. The 207 came in 84-87 XJ's.
Well your profile says 2.5 V6...there was no 2.5 V6...there was a 2.5 I4 and a 2.8 V6...
Depending on which engine it will be 4.10's or 3.55's...
2.5 I4 is 4.10's and 2.8 V6 is 3.55's.

lol....I forgot about that one...
Here's what I found on it...
NP242:
NP231:
Here's what I found on it...
The NP207 has a aluminum case and an appearance similar to the NP231. It should have a tag on the back saying New Process Gear, Model 207. This chain driven transfer case uses a 21 spline input with the manual transmissions and a 23 spline input with the automatic transmissions. The output for the front driveshaft is on the drivers side. Low range is 2.61 and high is 1.00. This transfer case is widely scorned. If yours should break, look for a 21 spline NP231 or swap transmission and transfer case at the same time. The transfer case is upsidedown in the picture showing the input (it is drivers drop.)
And some more...NP242:
The NP242 has an aluminum case and it should have a tag on the back saying New Process Gear, Model 242. New versions of the NP242 are refered to as NVG242 or NV242 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.
The chain driven NP242 is a full time transfer case with a 48/52 torque split front and rear. It is possible to lock it into four low so it behaves like a part-time transfer case. When it is locked in, power will be split regardless of traction. The output for the front axle is on the drivers side. Low range is 2.72 and high is 1.00.

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.
There are versions of this chain driven transfer case that take 21 and 23 spline input shafts. The 23 spline version is used behind the AX-15 and the 21 spline is used behind the AX-5 and the BA 10/5. The output for the front driveshaft is on the drivers side. Low range is 2.72 and high is 1.00.
If you own a 21 spline NP231 and you want to swap in a 23 spline transmission, you can either look for a cheap 23 spline NP231 at the junk yard or go to your local Jeep Parts Dealer and order up a new input shaft part #5300-6085. This is the part you need to convert your NP231 to 23 spline input.

There was a few that had the np242 in them. But most did have the np207
Let us know what it says on your t-case shifter bezel and we can tell you what T-case it is...
