New to me 2000 Cherokee - Maintenance Fluids

Hey guys,

I am finally back in a Jeep, picked up a bone stock, great condition 2000 Cherokee, auto. Its been 6 years since my TJ, so i need a refresher before i dive into the maintenance this weekend:

1. Engine oil - what's the optimal choice, 10W30? Also, how many quarts?
2. Transmission fluid - what do i get and how much of it? i plan to just drop the pan and replace the filter and gasket.
3. Diff fluids - i remember just under 2 qts each, but which weight? 80W90 or 75W140? Also, do we need to add any friction modifier?
4. I have no clue which fluid to use in the transfer case, or how much... any help?

Really excited to have a Jeep again and I'm looking forward to doing all this stuff this weekend. I'll post pics as I go.

Thanks in advance everyone.

You only need friction modifier if the rear axle has a Limited Slip. If you are unsure, buy the friction modifier and add it if you find a Limited Slip in the rear axle when you drain it.






Cherokee Fluid Capacities

Engine Oil

-2.5L (4cyl) - 4.0 Quarts (3.8L)
-4.0L (6cyl) - 6.0 Quarts (5.7L)

Cooling System

-2.5L (4cyl) - 9.0 Quarts (8.5L)
-4.0L (6cyl) - 10.5 Quarts (9.9L)

Automatic Transmission

The 4.0L (6cyl) AW-4 Automatic Transmission uses Transmission Fluid labeled Dexron-III/Mercon.
-Drain and Re-fill = 4 Quarts (3.8L)
-Filter and complete fluid exchange = 8 Quarts (7.8 L)
-2.5L (4cyl) Chrysler/Mopar Automatic Transmissions use ATF+3 or ATF+4 Type 7176

Manual Transmission

Chrysler recommends that 10w-30 motor oil be used in XJ Cherokee manual transmissions.

Jeep owners report good results with Synchromesh fluid.


-AX-5 5 speed manual - 3.3 quarts 75W-90 GL3 or GL4 (NOT GL5 or GL5 compatible as incorrectly stated in some Owners Manuals)
-AX-15 5 speed manual - 3.32 quarts 75W-90 GL3 or GL4 (NOT GL5 or GL5 compatible as incorrectly stated in some Owners Manuals)
-NV 3550 5 speed manual - 2.1 quarts Mopar fluid part # 04874464AA or Synchromesh (meets Mopar MS-9224 specs)

The NLGI specs are important - typical NLGI GL-5 gear oil carries added sulphur used as an Extreme Pressure (EP) lubricant. Especially when heated, sulphur is antagonistic to yellow (copper-based) metals - and the synchronizer rings and any bushings in the AX-15 are bronze. Most synthetic gear oils are rated GL-5 and are listed as "safe for use with yellow metals."

Unlike API specs (to API Service SL/CJ-4,) NLGI Service specifications are not reverse-compatible.

If you want to use a synthetic (RedLine, AmsOil, etc.) either check the back ofthe bottle or check the manufacturer's website to make sure it's safe for use with yellow metal. Using sulphur-bearing gear oils usually results in draining your synchronizer rings at your next fluid change...

Transfer Case
-NV231 Part-Time (Command-Trac) - 2.2 Pints (1.0L) Dexron-III/Mercon
-NV242 Full-Time (Selec-Trac) – 2.85 Pints (1.3L) Dexron-III/Mercon

Front Axle

-Dana 30 - 2.5 Pts (1.2L) SAE 75W-90

Rear Axle

-When equipped, Trac-Lok Limited Slip rear axles require 4 ounces of Friction Modifier Additive.

-Dana 35 - 3.5 Pints (1.66L) SAE 75W-90
-Dana 44 - 4.0 Pints (1.89L) SAE 75W-90
-Chrysler 8.25 - 4.4 Pints (2.0L) SAE 75W-90

For towing and off-road use SAE 75-140 synthetic

Thank you! This is fantastic!

Can you tell me how i know whether ive got a limited slip or not?

Also, any good brand for the fluids? Local dealers dont carry anything but ATF+4 and synthetic 75w140. Both are apparently "approved" according to ChrysCo bulletins, but id rather stick to the original.

Any good quality brand name fluid that meets the spec will be fine. The XJ Cherokee AW-4 transmission uses Dexron-III/Mercon.

Last thing, looking at SAE 75W90, they all seem to be synthetic. Do i get synthetic for the diffs?

Synthetic works, but unless you tow a lot, regular 80/90 gear oil is just fine.

I dont tow at all. And Im not concerned about the few bucks between conventional vs synthetic, but rather want to buy whats recommended.

If the 75W90 synthetic is recommended, thats what ill get, i just didnt think that any fluid spec'd for these Jeeps was synthetic. And im afraid of the synthetic being too thin in comparison to the conventional, or vice versa.
