Tranny fluid doesn't sound like a problem as long as it's not burnt. Do as I do and allow any tranny leaks to keep a fresh dose of ATF flowing.
I used to have a buddy who said that, LMAO...wonder what happened to that guy, dropped off the face of the earth...

...and LOL...leak? You mean constant fresh fluids, haha

CL. Gotta love it.

DEXIII/Mercon ONLY
I thought we were supposed to check these things in Neutral ??

Direct from my FSM

CHECKING FLUID CONDITION
Inspect the appearance of the fluid during the fluid
level check. Fluid color should range from dark red to
pink and be free of foreign material, or particles. If
the fluid is dark brown or black in color and smells
burnt, the fluid has been overheated and must be
changed.
Transmission operation should also be checked if
the fluid is severely discolored and contains quantities
of foreign material, metal particles, or clutch disc
friction material.
A small quantity of friction material or metal
particles in the oil pan is normal. The particles
are usually generated during the break–in
period and indicate normal seating of the various
transmission components.
REFILLING AFTER OVERHAUL OR FLUID/
FILTER CHANGE
The best way to refill the transmission after a fluid
change or overhaul is as follows:
(1) If transmission has been overhauled, install
transmission in vehicle.
(2) Remove dipstick and insert clean funnel in
transmission fill tube.
(3) Add following initial quantity of Mopar Dexron
IIE/Mercon to transmission:
(4) If fluid/filter change was performed, add 4
pints (2 quarts) of fluid to transmission.
(a) If transmission was completely overhauled
and torque converter was replaced or drained, add
10 pints (5 quarts) of fluid to transmission.
(b) Remove funnel and install dipstick.
(5) Operate vehicle until fluid reaches normal
operating temperature.
(6) Apply parking brakes.
(7) Let engine run at normal curb idle speed, apply
service brakes. Then shift transmission through all
gear ranges and back to PARK (leave engine running).
(8) Remove dipstick and check fluid level. Add only
enough fluid to bring level to Full mark on dipstick.
Do not overfill. If too much fluid is added, excess
amount can be removed with suction gun and
plastic tubing. Tubing only has to be long
enough to extend into oil pan.
(9) When fluid level is correct, shut engine off,
release park brake, remove funnel, and reseat dipstick
in fill tube.

Look on the transmission dip stick..

It tells you right there.

Seems we have a conflict, LOL

FSM clearly states in park, while dipstick says neutral...

I'm guessing either is fine, as long as its up to temp and running.

IT can be check while cold..

This is from CCKen..


A quick check of the trans fluid level can be accomplished when the trans is cold. This checks the Torque Converter and the trans pump.

With a cold trans, set the parking brake and place the trans in Park.

Remove the trans dipstick, rag it off, reinsert and check the cold fluid level. It should be near the top of the full line.

Rag off the dipstick again and set it aside. Start the engine then immediately reinsert the dipstick and check the fluid level. It should have dropped to near the bottom of the dipstick, which indicates the Torque Converter and trans pump are working. If the fluid level hasn't dropped to the bottom there may be something wrong with the Torque converter or pump.

If the fluid level dropped off the end of the dipstick, add small amounts of fluid until the level on the dipstick is up to at least the add mark.

Recheck the fluid level hot by driving the Jeep at least 15 miles to heat up the trans fluid, then check the fluid level with the engine idling. The fluid level should be near, or at, the top of the full range.


Now IM not sure if this is only for the 97-01..The pic from CCKen says 97-01 sooo hmmmm
Im sure its for all AW4s

My understanding of how automatics work is the fluid level needs to be checked at operating temperature and while the fluid is being circulated through the trans by the pump. It's not like engine oil in that it all drains back to the pan. Some stays in the valve body, torque converter, etc. Some transmissions don't engage the pump in park, only neutral (and in gear, of course). The AW4 runs the pump in park as well as neutral. My *assumption* is the manual writers figured all things being equal, it was safer to look under the hood with the trans in park rather than neutral, hence the wording in the FSM. Other automatics used in the XJ needed to be in neutral to run the pump, so if the dipsticks were shared between transmissions, they all said to check it in neutral to cover all the bases.

In other words, all autos can be checked in neutral, but only some can be checked in park.

I filled mine hot to the proper level in neutral and then let it sit overnight. Then took a file and marked the level on the stick. Now I can check it cold not running with MY mark. lol

I do this with everything I have owned. This whole checking hot, in neutral, In park, Etc. is for the birds. lol

This is a great idea. If I get lucky enough to pick this one up, I’m going to use this trick.
