2003 Xterra lines hanging by transmission

bump, because i have the same lines hanging down and i have no idea wtf they are.
As far as i can tell, they are supposed to be mounted to one of the bolts located on the side of the tranny, on a bracket. I have no idea why these come off, or if they attach to anything...
Does your X shift okay?

These are the breather tubes for the transfer case and the transmission, they are supposed to be mounted above the front of the bell housing of the transmission in the same area that the front differential breather tube is positioned. They are mounted high so that water doesn't go into the tube (especially when fording water).
Maybe during engine work, someone unbolted the mount (in the engine bay) and left it unbolted; over time, it worked its way down the side of the transmission. It will be difficult to work it back up to where it belongs. Find where it is supposed to mount, make sure you have a bolt, have someone with a rope from above pull it up and someone helping guide it from below. It's a very tight fit.
If you're up to the work, you can remove the transmission (adapter/extension housing) mount to give you some room above the transmission. Be very careful to support the transmission with a jack though.

As QuinE noted. These are the breather tubes. The one with the curved tube is from the transmission and usually bolts up to the top of the transmission. Mine was hanging when I bought my X a couple of years back. Do yourself a favor and just extend them up into the engine bay using some vacuum line. That way you don't have to worry about them picking up water and dirt from the road. I went one step further and attached a small filter to mine (looks like a mini cold air intake filter). THe most important thing is to have the end in a location where it willnot become submerged. Under normal operating conditions the tube is not likely to suck anything in, but if you drive through water the resulting cooling of the transmission will create a vacuum which can result in sucking said water in through the tube if it is submerged.
