Well, I have the famous tranny cooler line leak.

Well I was under the wifes jeep today doing an oil change and noticed the tranny cooler lines leaking and the undercarriage wet with atf. After doing a little research I see this is a VERY common problem, at least with 05's anyway. I looked on a few aout parts websites though and cannot locate the hoses. I saw another thread on here from last year where guys were getting them for around $40, where were they getting them from? I'm gonna do the repair myself but I'm gonna await till spring to do it because it was awful just doing an oil change in 20* weather and I don't have access to a heated garage. I'll just keep a close eye on the fluid level and top it off if it gets low. It doesn't look like too bad of a job, just maybe a pain routing the lines. I'm assuming these are quick disconnect lines? Do most auto parts stores sell the tool for disconnecting the lines? I have one already that has four different ends on it from when I had my ford with the quick disconnects for the fuel filter, will it work I wonder? Thanks for any tips or advice.

The lines connect to the radiator via a "C" clip and press fit with O ring...not sure if the same to tranny..pretty sure they are not the quick connect type. Below your post a few posts is a post with pictures of this radiator connection site. My lines have a slow ooze too at 38K miles which appears to be at the site of the crimped rubber lines. I have taken similar lines from an Audi that were leaking to a hydraulic hose shop (see Yellow Pages) where they have a crimping machine and had them "tightened" up. Worked great on the Audi lines and those things were under much higher psi than the tranny cooler lines off the Jeep. If the shop has similar crimp fittings they can put on new ones and hoses if you want..they didn't have Audi size fittings or I would have done that. I don't see any sites that have aftermarket lines so far..Dealer price is $400 or so ..worth getting that friendly hydraulic guy to see if he wants to give it a try...

I'll have to give that a try. My uncle has been a heavy diesel mechanic for 30+ years so I'm sure he knows somebody that works with hydraulics. I've seen posts though where people bought the new lines for around $40, i just can't find any anywhere online. And mine also appear to be leaking from the crimped area.

Hard lines with rubber hose flex sections x 2 for $40.00..great deal if true. I have taken the easy repair route in the past which consisted of cutting off the leaking crimped rubber hose sections and replacing with fuel resistant rubber hose and double worm clamps on both ends. A flare to the tube ends is a nice addition to prevent the hose section sliding off under pressure bur the 2 clamps(on both ends) well tightened have served me well since, once again, we are not talking about high psi's here.

I just was under my jeep and have the same problem one of the lines is leaking I have a 2007 Grand cherokee 46,000 miles on it. Also have a right side tire rub on the sway bar when wheel is turned all the way to the left. I have a appointment friday at the stealer. I just bought the jeep 3000 miles ago and have a bumper to bumper warrenty so hopefully it will be covered.
