I thought I remembered reading that in the 3sp Auto used before 03 the vent is inside the bellhousing and requires dropping the tranny and drilling out the top to extend the vent.

Jerry B has the 5 speed manual (although is looking into an auto, so he might still know)!

Jerry,
Where's the breather on the manual, is it possible to extend it? I've heard mixed things. Do you know if this is legit?:

I pulled it loose and w/o having to add any hose I was able to reroute it up to the metal brake lines right under the brake booster.

Also another note, where the tubes were connected to their origins they are clipped on with those spring loaded three prong clamps. So I feel those are good tight connections.

While I don't plan on forging a river I feel much safer knowing I can atleast forge water to the tops of my tires and be safe.


Same thing on my '04 Unlimited with auto. I pulled the T-case vent line out of the x-mas tree at the top of the vent line and routed it over to the transmission dip stick. From underneath it appeared to have lazily wandered forward on the passenger side and then crossed over to the driver side where it was clipped to the bell housing. Plenty of slack for re-routing. I wonder why it wasn't placed higher in the first place?

Just wondering how you elliminated all the metal shavings from your trans after drilling and tapping that new vent. It is hard to tell from that picture where exaclty on top the new vent line should go, or maybe it doesnt matter too much as long as it's in the body of the trans.

04 is fine. Here are the vent locations:
Transfer Case
The t-case vent comes up the other side by the brake booster.

T-case - Ziptied around the brakelines cloes to the master cylinder
Transmission
My 2003 and > auto has a vent hose zip tied to the tranny filler tube near the top. As far as I know, all 2003 and up autos have this vent hose.

I just crawled under there and took a good look. There IS a metal tube coming out the top of the tranny (it exits parallel to the ground and bends 90 degrees upward. At that point a black tube is attached with a red zip-tie. The tube goes forward but I lose it just behind the bellhousing. My jeep isn't lifted and I can't seem to get a good enough angle in front of the skid to see where it goes.

Tranny - Ziptied to the tranny dipstick tube near the top.


Front & Rear Differentials
The diffs are already vented pretty high. The rear axle is vented near the gas filler. The front is somewhere in the engine bay.

The front axle vent comes up the left side of the radiator - ends just short of the top of the radiator.

Front diff - Upper driver side corner by the rad overflow bottle

Rear diff - Ziptied to the the gas fill tube close the the fuel cap
