Here's a list of the different fluid capacities for various Wrangler TJ models.

Engine
2.5L 4 cyl - 4 quarts
2.4L 4 cyl - 5 quarts
4.0L 6 cyl - 6 quarts


Transmission
30RH 3 speed auto
ATF+4 is replacement). See post #2 below for fluid amount. Make sure to use ATF+4, not just ATF!

32RH 3 speed auto
Approximately 4 quarts ATF+4 is replacement) when drained via dropping the pan / Approximately 8 quarts dry fill. See post #2 below for FSM procedure. Make sure to use ATF+4, not just ATF!

42RLE 4 speed auto
Approximately 4 quarts ATF+4 when drained via dropping the pan / Approximately 8.8 quarts dry fill. Make sure to use ATF+4, not just ATF!

AX-5 5 speed manual
3.3 quarts 75W-90 GL4, or 10W30 (NOT GL5 or GL5 compatible as incorrectly stated in some of the manuals). I highly recommend Redline MT-90.

AX-15 5 speed manual
3.32 quarts 75W-90 GL4, or 10W30 (NOT GL5 or GL5 compatible as incorrectly stated in some of the manuals). I highly recommend Redline MT-90.

NV3550 5 speed manual
2.1 quarts. I highly recommend Redline MTL.

NV1500 5 speed manual
2.4 quarts. I highly recommend Redline MTL.

NSG370 6 speed manual
1.58 quarts. I highly recommend Redline MTL.


Transfer Case
231
1.1 quarts ATF+3 or ATF+4

241
2.1 quarts ATF+4

NOTE: The 231 and 241 transfer cases are fine with any type of good quality ATF. Mercon, Dexron, ATF+4, etc. are all fine. Only the automatic transmission is fussy about the type of ATF it gets.


Axles
Dana 30 - 1.25 quarts 75W-140
Dana 35 - 1.75 quarts 75W-140 *
Dana 44 - 2 quarts 75W-140 *
Rubicon Dana 44 (FRONT) - 1.375 quarts 75W-140 synthetic
Rubicon Dana 44 (REAR) - 2 quarts 75W-140 synthetic **

* 4 oz of friction modifier is required with Trac-Lok limited slip differential.
** Friction modifier is NOT required with Tru-Lok locker/limited slip differential (factory Rubicon locker).



Cooling System
The Jeep Wrangler TJ came with a HOAT coolant from the factory. I always recommend running OE Mopar coolant or Zerex G-05, which are both HOAT coolants.

2.5L - 9 quarts
2.4L - 10.1 quarts
4.0L - 10.5 quarts

Automatic Transmission Fill Procedure per the FSM

32RH and 30RH (97-02 3 spd auto)

To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
  1. Remove dipstick and insert clean funnel in transmission fill tube.
  2. Add following initial quantity of Mopar ATF+4 to transmission:
    1. If only fluid and filter were changed, add 3 pints (1-1/2 quarts) of ATF+4to transmission.
    2. If transmission was completely overhauled, torque converter was replaced or drained, and cooler was flushed, add 12 pints (6 quarts) of ATF+4 to transmission.
  3. Apply parking brakes.
  4. Start and run engine at normal curb idle speed.
  5. Apply service brakes, shift transmission through all gear ranges then back to NEUTRAL, set parking brake, and leave engine running at curb idle speed.
  6. Remove funnel, insert dipstick and check fluid level. If level is low, add fluid to bring level to MIN mark on dipstick. Check to see if the oil level is equal on both sides of the dipstick. If one side is noticeably higher than the other, the dipstick has picked up some oil from the dipstick tube. Allow the oil to drain down the dipstick tube and re-check.
  7. Drive vehicle until transmission fluid is at normal operating temperature.
  8. With the engine running at curb idle speed, the gear selector in NEUTRAL, and the parking brake applied, check the transmission fluid level. CAUTION: Do not overfill transmission, fluid foaming snd shifting problems can result.
  9. Add fluid to bring level up to MAX arrow mark. When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.

Orygun, the wet side...
Remember to remove the FILL plug first when changing fluids on the manual transmissions and all transfer cases. Sometimes it just doesn't want to come out, and it's nice to be able to put new fluids back in after you drain out the old fluids. Also, the fill plug on the AX5 is on the passenger side of the transmission, not the drivers side. I know the plug on the drivers side looks like a fill plug, but it's not. Don't touch it.

Hey so whats the benefit of either 80W-90 or 75W-140? There seems to be a little price jump for the 75W-140..

Also i have a D30 up front and a D35 in back, will 3 quarts be exactly enough to do both?

The 75W-140 gives you a greater temp range of operation. Are you running lockers in your Diff?

No lockers. Ok so that means the 75W-140 is better for heavier duty use and 80W-90 would be more suited for lighter duty?

Without lockers your Diff capacity should be roughly 3 qts between the front and rear. I would go 75w-140 to cover you.

OK and then do I need 4 oz of friction modifier?

so question have a rubicon so it says friction modifier is not required. So i just click on the link to the Mobil 1 on Amazon and bought 4 quarts but i think they sent me the wrong thing which has Fiction Modifier included. Will it hurt anything if i use it? or should i return and get something else without it? has a different part number than what is listed on Amazon page

sorry for noob question. says works for conventional and LS. but first time changing diff fluid and don't want to put in the wrong thing

All 03-06 Rubis have a limited slip rear diff, in addition to the air lockers in both diffs. It does not require friction modifier, because it is a gear-based limited slip rather than clutch-based like the Trac-Lok available on other TJs. Doesn't hurt to use it if it's already in the oil, but no reason to pay extra to add it.

For those with a G2 DANA 44, they (G2) recommend 85W-140 GL5.
