I've always owned manuals till now....do I just check it with the libby running?

Running, in park, on a level surface, warm tranny is best.

I was under the impression that the transmission needed to be in NEUTRAL for DCX built vehicles? I don't have my owners manual in front of me - but can someone confirm if we check the fluid level with the gear in Park or Neutral?

~Thanks!

I've read "put it in Neutral" on here, so that is what I've done whenever checking the fluid...

That is what I thought... I've been pulling the parking brake - putting the shifter in N and (with the engine running & warmed up) checking the fluid level of the transmission.

Maybe the gassers are different?, it probably says right on your dipstick how to check it, and certainly in the owners manual.

Good lord, this is getting silly, did you know the 07's dont even have a tranny dipstick?! Its bad enough with all the electronic gizmo's that you need a code reader to even begin to diagnose a problem, before you know it they will go back to not even letting you pump your own gas

OK - thanks for clearing that up.

BTW we should note (for those new to Mopar, Jeep or DCX) that the Liberty takes the Chrysler specific ATF+4 blend of transmission fluid for all automatic transmissions in case you need to add some to your transmission.

in jersey you cannot pump your own gas they make you take a safety course and get certified to operate a fuel pump in order to work at a gas station.

and right out of my '03 manual it says

1. the vehical must be on level ground

2. the engine should be running at curb idle speed for a minimum of 60 seconds

3. fully apply parking brake

4. apply the service brakes and shift the transmission in D (drive) and R (reverse) for a minimum of 2 seconds in each gear position. shift into N (neutral).

5. the fluid (b)MUST(/b) be checked with the transmission in N (neutral)

6. remove the dipstick and feel if fluid is hot or warm. hot fluid is approximately 180*F (82*C) the normal operating temperature after the vehical has been driven atleast 25km (15 miles). the fluid cannot be comfortably held between the finger tips. warm is when fluid is between 85* and 125*F (29* and 52*C)

7. wipe the dipstick clean and reinsert until seated. Remove dipstick and note reading.

a. if fluid is hot the reading should be in the crosshatched area marked OK

b. if fluid is warm the reading should be above the "Min" hole and below the circle in the crosshatched area.

8. if fluid is low add sufficiant fluid to bring to the level.

fluid is added through the dipstick hole.

for 42rle tranny's

put in park to check for the 45rfe tranny's

Yep...Jeger is right in the 24 years of servicing all types of auto trannys I've heard P or N warm fluid and level surface.P and N are really the same gears(out of gear) one just keeps the vehicle from runnin over stupid people while there checking there fluids. I think Jeger is just trying to protect these people. :lol:

and to add fluid, is there a filler neck or does it go down the dipstick tube?

O_Dogg · **Posted:** Sun Jan 14, 2007 5:23 pm

down the dipstick tube via a tranny funnel just a reg funnel with a length of hose attached to it

That reads a little consuing to me at the bottom, I have the 45rfe, so it should be in park with the fluid warm after shifting into drive and reverse and :
a. if fluid is hot the reading should be in the crosshatched area marked OK

b. if fluid is warm the reading should be above the "Min" hole and below the circle in the crosshatched area.

is that correct?

yepper same procedure just check it in park not neutral. and yeah on the readings as well that is straight out of my '03 manual :wink:

This is for the same model tranny so I assume it should be the same procedure (it's the same as posted above, just a little clearer to read )

The car should be parked on a level surface, engine running, in Park or Neutral (I prefer park so it stays in one place).

The oil should be hot to the touch (180°F) and between the two holes marked 'HOT'.

The oil is red with a new vehicle, but the dye wears out quickly. Dark brown is OK. Black & lumpy obviously isn't. Pink & frothy means you have ingested water and need new fluid NOW.

MOPAR ATF +4 is expensive, but it's actually pretty good at protecting gears & rotating stuff. Also the clutch material it selected to work with it. Use of a different fluid will void your warranty and could have unexpected side effects on shift quality.

If you need to add fluid, add it through the dipstick and find the leak. Transmission oil does not evaporate. If you're low, you're probably leaking.

I hope this answers all questions.
