Hi folks. I am a newb. I am the owner of a 2004 TJ. I was lubing the front end and I saw this. It is a hose with a white nipple on it and it was hanging against by exhaust pipe on the passenger side. It has a black tie down attached to it that looks like it may have broken away from where it should be attached. I've been trying to figure out what it is. Thanks in advance for any help.
It could be either. You'll need to trace it back. If it's the breather for the transmission it should be up on the firewall by where the trans dipstick is. That's where it is on mine anyway. The higher the better also.
