Ive got an 02 also and mine is leaking from one of those pipes. Its not the one shown patched this in photo but the one that runs parallel to it, right next to it.
I was wondering what that line was called, where it goes. I need to find the part number.

Any help would be great

Not sure which one of mine is leaking but I am going to be cutting a 2 foot section out of it tonight at work and installing a section of hose. The line was covered with a foil covered fabric protector, which while I'm sure it provided heat protection, sure did do a good job at retaining salt water during the winter. I just hope I have room enough get my hand in there to push the hose on where it goes up to the top of the tranny. Leaking at the bend there and also above the forward cross member. Sure not looking forward to having to drop the tranny. Guess I better pick up some tranny fluid on the way to work as I'm sure I'll lose some when I cut the line. Don't really care what it looks like, just as long as it stops leaking.

Mine is leaking in the same exact spot! Right above, what appears to be, the cat. converter. I kept smelling burning oil and noticed a puddle about the size of a pancake in my driveway. Crawled under there and its dripping out of the "foil covered" part of line

I looked at the lines and I really do NOT want to replace all of the lines, looks like a royal PITMFA.

Putting a piece of rubber hose down there with 2 clamps kinda freaks me out because tranny fluid + very hot cat. converter = fire. I also dont see how I'd have the room down there to put in compression fittings. I have about 4" to work between the trans and the cat. converter.

I picked up some tranny cooler hose from Autozone yesterday and I used some hose clamps from Kmart. I was in a hurry and Autozone was out and I was on my way to work. Man those are some cheap azz hose clamps. I think there were made from a cheap aluminum alloy. It's a good thing the hose went on as hard as it did and there isn't any kind of real pressure on that line. I stopped at Advance here in North Chicago on my way to work and got some good fuel line hose clamps, the kind that has the nut and bolt setup instead of the worm screw thingy. Replaced the clamps and now my only concern is if the catalytic converter puts off enough heat to affect the hose. Wonder if I could get some of that foil covered sleeve material that caused this problem in the first place.

Thats my concern too. If that hose melts or pops off, you better pay attention because ATF will start a fire. Ive used rubber hoses in the past with clamps, but never that close to the exhaust. What a retarded design. I wonder what engineer was smoking crack the day they approved it for production!

I was thinking about using rubber hose, but looping it way high up in the frame and zip tieing it to something, so that its away from the exhaust....

Either way, Im going to call around tmo for some quotes for full replacement or maybe splicing in some metal line with compression fittings.

Personally I think that every engineer that designs any part of a car needs to remove and replace that part after the vehicle has been completely built. Especially oil pans and oil filters. And why isn't there a drain plug for the tranny pan? Ever try to drop one of those without making a huge mess?

I totally agree!!

What I do now with the trans pan, I have a marine engine oil changer. I hook that up to the dipstick and siphon out a few quarts, and then drop the pan.

Before that though, I def. ruined a few good shirts dropping that pan

I would venture to say there is an after market kit to install a drain plug. Might consider doing that on my next vehicle.
