How do you disconnect the transmission cooler line that goes into the radiator... looks like it uses some kind of quick disconnect fitting? Do I need some kind of special tool for this? I bought two different sets of fuel & a/c line disconnects and tried different ones every which way but still couldn't get it to come off. I don't know if I'm using the wrong tool, using the tool the wrong way, or if my fitting is somehow just messed up and not releasing... can someone point me in the right direction here?
These are what I bought (maybe not the exact same ones, but the same type): http://www.autozone.com/autozone/acc...fier=2356_0_0_
and http://www.autozone.com/autozone/acc...uestid=2885498

squeez the clips with angled needle nose plyers or what ever gets the best grip and push the hose in and then pull out. clean all the gunk with carb cleaner around the clip first.

All I have to say is good luck. My 98 never had them messed with and it was sheer hell to part them. I ended up cutting the rubber and ordering new ones...
Here is a quick write up on how to disconnect the lower transmission line on a Jeep Cherokee. The top one just unscrews. You cannot unscrew the bottom one (at least in a 99). I tried unscrewing it, but it won't disconnect from the radiator....that's because it's part of the radiator.
The lower one has a strange connector that is similar to fuel lines and AC connections. There are little fingers inside the metal part. That look like the first picture.
To get it off you will need something like the little plastic things that I got from Autozone (whole kit 9.99). I used the light blue one.
Last picture is how the little plastic thing goes on the line. Once you get it on, push it as far as you can, then wiggle the metal part of the transmission line until it is free. Pretty quick once you figure out what you need to do.

late to the game here. am I stupid? bought these little disks and I can't get the lines off for the life of me. 99 cherokee, got the whole dang radiator ready to come out besides these trans lines
thanks for your help!
There could be a bunch of dirt and junk in the fitting. Try spraying some WD40 in there, and working the removal tool.
I just replaced my radiator last year, and my fitting was a little stuck. Not terrible, but some patience and working the removal tool into place worked.

Here is the easier and better way to deal with them, since you are not a factory needing to make productions lines run smoothly:
Cut those stupid things off and just use regular fuel-grade hose and normal hose clamps. They are every bit as reliable and a lot less hassle.

Cut mine off after struggling with those BS line connectors for a half hour. Piped in a tranny cooler while I was in there and now my center console doesn't get hot.
