Any advice? This WJ is new to me. I attached some photos.

That's probably about right for a 17 year old Jeep! It may have taken a long time for that amount of fluid to seep and soak like that. If the fluid reservoir only needs to be topped off a few times a year, I wouldn't worry too much about it until I had to (leak worsens, pump starts to go, etc.).

Rage! Rage against the dying of the Jeep.

Interesting - should I wipe it down and start fresh? Thanks - can't beat the do nothing answer to a question!🏆

Well, of course if you don't clean it all up first there's no way to know where the leaks (yes, probably leaks - plural) are coming from! So, if you're dead set on fixing it, then get some Purple Power, Mean Green, or some other degreaser and clean it all up the best you can. Then, watch for the subtle leaking to reappear. After that, you'll probably realize you need several parts (or more) to completely eliminate all seeping completely.

Really, your individual goals and expectations are going to drive the entire process - from do nothing all the way to better than factory new condition. If that's not defined, then advice from others is going to probably not align with your expectations! I know how *I'd* deal with it!

"First do no harm!", "if it ain't broke don't fix it", etc., etc. I used to be a little more enthusiastic about tearing into stuff than I am these days. There were some hard lessons learned, that's for sure.

I think I can do that!

Wow are they? What does it mean if they are wet? The transmission pan is also oily.

It appears to be Trans cooler lines as stated above. My first move is to follow 99WJTX and clean everything REAL good. I like using the degreaser in the wash bay at the local car wash, and getting wet while blasting all the oil spots from underneath.(bring your rain gear). Then start by snugging that hose clamp at the fitting. Its common knowledge that rubber hoses shrink over time, and that causes the clamps to become loose, allowing seepage like you are seeing. Squeeze it down until you see just a slight bulge of rubber protruding through each slot in the clamp.(slight bulge-did i say slight?) then run it and see if the hoses get wet again. The fluid tends to get blown all over the place under the hood while you are diving, if you start with clean surfaces, and check it often after cleaning, you will better be able to spot exactly where its coming from.



P.S. might wanna replace any squeeze clamps you find along the way as well. They are known to leak after a few years age as well. ( the other hose near the radiator)

Good catch. I didn't look closely enough and thought they might be power steering hydraulic hoses but I agree now they appear to be trans cooler lines.

Great! I was thinking about having my mechanic friend change the trans fluid - it is very brown like motor oil. Since it looked leaky on the transmission pan (though that is likely the 4.0L's rear leaking) - I ordered a new mopar gasket, mopar fluid and a filter. Is it crazy to change out these leaky looking hoses at same time? Is it a big job? Also I watched the youtube below on adjusting the bands -in the 42re...

You can get transmission specific hose from an auto parts store. I believe O'Reilly for one stocks it. It looks like fuel hose but it's transmission fluid tolerant and formulated properly in that respect. I can't remember what the size is and I'm not sure it would be the same on a 4.0 anyway. You can remove a section and take it with you to the store to match it up. I believe on the 45RFE/4.7L combo it's either 5/16" or 3/8" ID. I'm leaning toward 5/16" though.

Great! Thanks a lot! Maybe I should start a new thread about this - since it is titled wrong. I would love to know about adjusting the bands - with my past jeep and Ford trucks etc... I always pulled the pan and changed filter - cleaned magnet and refilled - but never tried to adjust the bands. Also I know some people say there are better ways to change the trans fluid then just letting gravity do it's thing once the pan is off....
