Vent lines

[Kejtar]

ok, I found my vent line for the rear axle and front and the t-case... but I couldn't find a vent for my AX15.... is there one?

Btw it's a 98

Just this past week I went on a similar hunt for my 99 TJ AX-15's vent hose and found out it doesn't have one! There's a vent and vent cap on top of the tranny right behind the shifter. I left it alone so I'm not sure if you can remove the cap and put in a hose.
Jeep on!

grrr.... that's not good... I don't like that :( That oil is expensive enough that if I get it submerged I don't want to have to flush it and replace it :( :(

If you figure out how to get the cap off, please let me know! I was afraid I'd break the cap and be even worse off than before.
Pull out the center console and pop up the access plate around the shifter, you should be able to see the vent. My Comanche is an 88 and I'm not certain what the access cover looks like on the newer body style. Or you can drop the tranny if you were feeling *really* ambitious. ;-)
Jeep on!

I will definately post it.... but it will be a while... its seems that this will be a project for summer :)

[Pete M]

That's fine, I don't think mine will drown while sitting in the garage. ;-)
Jeep on!

Remi, check you're tranny again, I do seem to recall a vent hose on my '94 AX-15, there may be some diffrences between the years.

[Kejtar]

Hmm.. sounds like I need to pop the access plate from the top, but I gave it a good bearhug and felt it all around and the only hose that's in the area seems to be the t-case hose. On the other hand, I did feel something that sounds kind of like what Pete is describing.... damn talk about a stupid cheap solution! The main reason I am on this is because the valve thing on the end of the t-case hose seized shut and I ended up putting the fuel filter.... so if that seized, how am I supposed to trust the other thing?

P.S. Why does it feel like that almost every factory modifications not an improvement :( ?

[Scott Mac.]

You may be right, I remember fiddling with my reverse light switch and feeling a hose up there. It was probably the t-case vent.

[Kejtar]

Yup.. that's probably it: the t-case hose kind of goes over and almost across the Tranny... if you follow it out, it comes off capped on the passenger side of the engine bay in the back by the block. For me it was a black hose with white end piece..... I took the end piece off as it was stuck in the closed position (found that out when I opened the t-case to change fluid and I had the pop/air inhalaction of a vaccumed container :( Anyways, I put on a fuel fitler for the "breather" and continued the line up to the top of the bay and then I lopped it so water would not be able to go in directly :) :)

Because you're talking about Chrysler Corporation (okay, now DaimlerChrysler). It was Chrysler all on their own that bought Jeep from AMC, took a well-designed and pretty thoroughly optimized design -- the XJ Cherokee -- and proceeded to further "optimize" just about every component they could get their grubby mitts on.

They failed to follow the obvious dictum "If it ain't broke, don't fix it." Not only did they generally not really fix what was broken, they cheapened everything that wasn't broken. Chrysler's changes were not improvements to the vehicle, they were improvements to the profit on every XJ sold.

Hey all, I've got 3 vent lines in the engine compartment, all go somewhere...the "white" vent cap goes to the d30, the "black" vent cap to the t-case, and the "big black" vent cap to the ax-15. The ax-15 line is larger than the others, and includes a rubber line that goes to a hard line.
Is this just an up-country suspension thing? I'm wondering if DC just designed them that way and not the other "non-up country" models ??

[Kejtar]

what year is your jeep Pale Horse? I have a 98XJ with up country.. and if anything I'd expect this one to have the vent line as it's suppose to be a the off-road type package...

[Pale Horse]

I guess it helps if you include that stuff....99 sport, 2 dr w/ up- country.

[Pete M]

My tranny is from a 99 TJ. I installed it myself and I know there's only a single 2 foot vent line coming off the assembly (I have no idea where it was routed on the TJ) and what apears to be a vent cap (like a little upside-down soup can) on the AX-15 right behind the shifter tower. It would not suprise me in the least to find both methods in use by Jeep at the same time. ;-)
Jeep on!

Hmmmm.... 4.0 liter HO engine, Open Cooling System, ChryCo 8.25" rear, non-vacuum disco front, these all seem like improvements to me.

And God forbid that a Corporation would want to make MONEY. Even worse: MORE MONEY. Frankly, I like living in a capitalist economy where private companies can build products and sell them for profit.

But...

4 carpet rails instead of 6
No map pockets (just ask Kejtar!)
Dana 35C
Composite Rotors
Cheaper seats

That's all I can think of off the top of my head...but there's more

They did do some good...but they also did some bad, although I'm glad they brought the 4.0 in in '87.

[Kejtar]

Yeah.. My 98 had no map pockets which I think was really really ridiculous.
I was a bit facetious when I was talking about the improvements.. but look at couple other things: longer yoke, low pinion front ends in even newer ones..... so maybe for every new improvement they did a negative thing?

Oh yeah... you're talking about money: how much do you think it cost to mold the door panel to have a map pocket? Probably not much... but I am almost willing to bet money that they ended up loosing quite a few sales for the lack of them as they added them back again in the later models.

I installed a AX-15 out of a '97 or '98 XJ into my '88 and there wasn't any vent line on the tranny. There was a little brass colored tube on the top with a cheap looking breather cap. I didn't trust the little cap to keep water out so I pulled off the little cap an ran a vent line up the fire wall and cap the end with a little air filter. The little tube sticking out of the tranny was pretty short if I remember correctly so I use tie-wired to secure the vent line to the top of the tranny. Good Luck.
