[ILikeMud]

Transfer Case Specs

ZJs came with 3 transfer cases the 231 Select Trac, 242 Command Trac and 249 Quadra Trac.
NP/NV231 – Command Trac – was a rare option. The shifter has 2HI-4HI-N-4LO on the bezel. It’s a very good all around transfer case and the same case as what the YJs and TJs use. It is a chain driven driver side drop transfer case. The low range is 2.72 and high range is 1.00.

NV/NP242 - Select Trac – The 242 had an optional full time 4WD selection on the case to be used in adverse weather conditions such as rain/snow storms for added traction and safety. The shifter has 2HI-Full Time 4WD-4HI-N-4LO on the bezel. It is a driver’s drop chain driven transfer case. The full time torque split is 48 front and 52 rear. Low range is 2.72 and the high range is 1.00

NV249 - Quadra Trac – The 249 was a Full Time 4WD transfer case with no 2WD option at all. The shifter has Full Time 4WD-4HI-N-4LO on the bezel. I do not know what the low and high ranges were.

Transmissions

Most ZJs came with a 4spd automatic transmission but a few 1993 models can be had with the factory 5spd manual transmission. It was a very rare option however so your chance of finding one is fairly slim.

AX15 – This was the 5spd manual transmission in the ZJs. Only used in 1993 models to my knowledge. It uses an external slave cylinder for the clutch. With the exception of the slave cylinder it is the same internally and externally as any other AX15 transmission.

42RE – 4spd electronically controlled automatic transmission found behind the 4.0L Inline 6 cylinder engine in ZJs. Not a very strong transmission and has a history of failure. There is very little to no aftermarket support for this transmission.

46RH – 4spd hydraulically controlled automatic transmission found behind the 5.2L V8 cylinder engine from 1993 till 1995. The 44RE replaced it in 1996. The 46RH is stronger then the 42RE and has a better history. There is some aftermarket for this transmission.

44RE – 4spd electronically controlled automatic transmission found behind the 5.2L V8 cylinder engine from 1996 till 1998. Not as strong as the 46RH but a good transmission none the less. There is some aftermarket for this transmission.

46RE – 4spd electronically controlled automatic transmission found behind the 5.9L V8 cylinder in 1998 only. It is similar in strength to the 46RH. There is some aftermarket for this transmission.

If and when you have to purchase a new transmission for your ZJ, make sure it is a 4WD transmission that you are buying. There are 2WD versions out there.

Engines

A total of only 3 engines where offered in the ZJs, the 4.0L Inline 6, the 5.2 V8 and 5.9 V8 (1998 only).

4.0L Inline 6 Cylinder – The 4.0L Inline 6 cylinder engine comes in at 232 cubic inches. Horse power is 190 at 4750RPM with torque being rated at 225ft-lbs at 4000RPM.

5.2L V8 Cylinder – The 5.2L V8 cylinder engine comes in at 318 cubic inches. Horse power is rated at 220hp and 285ft-lbs of torque (increased to 300ft-lbs in 95). I don’t have rpm numbers.

5.9L V8 Cylinder – The 5.9L V8 cylinder engine comes in at 360 cubic inches. Horse power is 245 at 4000RPM and 345 ft-lbs of torque at 3200RPM. The 5.9L V8 was only offered in the 1998 5.9 Limited models.

few changes:
there is aftermarket for the 42re: I have a shift kit, upgraded clutches, and a few other things in it.
4.0L = 242 ci

249 had same ratios as 242 231
93-95 249's had no low lock
96-98 249's had low lock and can safely remove front driveshaft to get 2wd

93-93.3ish was possible to get the AW4 transmission in the 4.0L's which was an 4spd electronically controlled automatic transmission and is very much like the tranmission in the Toyota Supra than can be modded to take 10 second passes. plus you can use this sweet shifter on the AW4

[ILikeMud]

Thank you sir!

[redzj]

I thought the 242 had an 50 50 split in FT. Isn't it just an open differntial with spider gears in the Xfer case?

[SirFuego]

Awesome writeup.

One thing, though. I have a 93 ZJ Laredo 5.2L, and it has the D35C rear axle, so the 44a isn't on all V8's. Perhaps they were put on V8's after year 9X?

[DJJordache]

yeah your right I didn't catch that one 93-95 ALL ZJ's got the D35c, only 96-98 v8's got the 44a. and I think I read somewhere that overseas ZJ's could get the IRON 44

[Firestarter]

the AX-15 was an option until mid-year 95. 250 or so models were made throughout the 5 spd's run

[nate]

Yeah South America for sure. The week after I put my 8.8 in, I could have got one for like $400. D'Oh!

You mean different versions, or is that a typo. Only 250 5 spd trucks?

[Firestarter]

250 5 spd ZJs were built all in all

Where can you find those figures, if that's true, I need to get my rig documented as "x of 250"

What about the 4.7 that everone talks about so asically 44re or 46rh will bolt up and can be used in a 5-2 orvis with a dana 35c v8. Thanks guys for your help but the orvis also came with the up counry 1" lift and front and rear tow hooks.

WTF the 4.7L was never in a ZJ, 44re never came with a d35c DUH!

[Sporer65]

Another package was the Grand Wagoneer. It was available in 1993 only and had almost every option standard. I think I saw somewhere that there was 25,000 made.

Also 1993 had drums in rear for all models and they were optional on Limiteds in 1994.

[2drezq]

Small correction: The SE model was, indeed available in 4WD. I only wish mine was the rarest of the rare 5-speeds! I saw one, once.

[cataclysmcow]

Can anyone add some stock suspension measurements to this?

[ajmorell]

No, it's not 50/50. I believe PT has the 50/50 split.

[MUDDTRACKS]

more corrections for you

My zj is a 98 leredo se 4x4 everything is about the same as limited but a few gadgets and the v8
