Re: 2004 WJ 4.0 trans/ATF level questions
I had no idea that ATF expanded so much over a limited temperature range,
that chart came a surprise.
You should really change your fluid every couple years, it would be best to
change the filter too.
If you add a drain plug in the pan (a few dollars at any auto parts store)
ATF changes become as easy as motor oil changes.
You can also snake a very thin tube down the dipstick hole and siphon the
fluid, you can usually get 4-6 quarts by this method.
Be sure to use ATF+4 ONLY, never a 'universal' fluid or an additive to make
some other brand the same as ATF+4 (they don't). It is available in Mopar
and Valvoline brands at your local auto parts store.

>> Procedure One and Two from my '02 FSM, please note the graph in part Two
>>
>> PROCEDURE ONE
>>
>> (1) Transmission fluid must be at normal operating
>>
>> temperature for accurate fluid level check. Drive
>>
>> vehicle if necessary to bring fluid temperature up to
>>
>> normal hot operating temperature of 82°C (180°F).
>>
>> (2) Position vehicle on level surface.
>>
>> (3) Start and run engine at curb idle speed.
>>
>> (4) Apply parking brakes.
>>
>> (5) Shift transmission momentarily into all gear
>>
>> ranges. Then shift transmission back to NEUTRAL.
>>
>> (6) Clean top of filler tube and dipstick to keep
>>
>> dirt from entering tube.
>>
>> (7) Remove dipstick (Fig. 87) and check fluid level
>>
>> as follows:
>>
>> (a) Correct acceptable level is in crosshatch area.
>>
>> (b) Correct maximum level is to MAX arrow
>>
>> mark.
>>
>> (c) Incorrect level is at or below MIN line.
>>
>> (d) If fluid is low, add only enough Mopart ATF
>>
>> +4, type 9602, to restore correct level. Do not overfill.
>>
>> Procedure Two requires a DRB tool and temperature correction. I found
>> the
>> chart surprising so I will post a link to it.
>>
>> PROCEDURE TWO
>>
>> (1) Start engine and apply parking brake.
>>
>> (2) Shift the transmission into DRIVE for approximately
>>
>> 2 seconds.
>>
>> (3) Shift the transmission into REVERSE for
>>
>> approximately 2 seconds.
>>
>> (4) Shift the transmission into PARK.
>>
>> (5) Hook up DRB scan tool and select engine.
>>
>> (6) Select sensors.
>>
>> (7) Read the transmission temperature value.
>>
>> (8) Compare the fluid temperature value with the
>>
>> figure. (Fig. 88)
>>
>> (9) Adjust transmission fluid level shown on the
>>
>> dipstick according to the figure.
>>
>> NOTE: After adding any fluid to the transmission,
>>
>> wait a minimum of 2 minutes for the oil to fully
>>
>> drain from the fill tube into the transmission before
>>
>> rechecking the fluid level.
>>
>> (10) Check transmission for leaks.
