Plugs into the top of the transfer case. Think it's an overflow.

shintastrife

ok, will look in to it more when have more day light and things.

Nah, it's a breather tube. For the T-Case I think.

Hommersimpson

anyone have pic of were it goes ontop of tranny ? mines just hanging and i need to put back in...

shintastrife

i know i have the vac system 4wd , and its not wroking then again i just go the thing to go in to 2wd.

if you guys know how to over ride this let me know would lover to do that save me time and money.
i know there are write ups on it but i cant seem to find them

mike albo

are you sure its not a cooler line?

shintastrife

5 speed trany dont thing so

It's the same way on mine. Attaches to the top of t-case, routes over the top of the tranny, and bolts I think between the tranny and the engine. Mine just hangs though, like in your picture. The guy before is probably right, a breather tube, really shouldn't have that much fluid for it to be an overflow. That, and the EPA probably wouldn't be too happy about overflowing transmission fluid. I suppose it could be vacuum, but there's nothing in that range that would connect it to the vacuum system.

Just curious and maybe I read this earlier, are you having any issues with 4 wheel drive? I'm betting you're running an ax15 tranny with a 231 case

shintastrife

i know its stock the dealer i got it form side the guy never touched it all he did was just drive it. so what ever was stock for the 1990 cherokee is what i have. going to get under it to day and look.

but yet i am having trouble with my 4wd. i fixed the linkage to changes if form 2 to 4wd. but i dont think the front isnt locking in like is should.

was going to over rind it but have not clue where to start.

what happens when u shift into 4wheel....do u have power to the front wheels or just all in the rear still

shintastrife

its all in the rear form what i can tell. i put it in 4L b/c i know 4h i can tell it if is or not. but it still seem like its in 2wd

claygrassmann

pretty sure its not a cooler line cause if it was your tranny would be toast right now

have someone watch your front drive shaft to besure its spinning, with the rears on ice or the whole thing on jack stands, wouldn't jack just the rears. if it is, theres a disconnect on the right side of the front axle that usually goes bad, the got rid of it in '91. its vacuum actuated so check for vacuum there when in 4wd. if there is you can replace it, or get a cable actuated one that you manually pull yourself, or i think you can scrap the 2 piece shaft with a one piece from a '91 & up. theres probally a write up on here on how to & what you'll need. let us know what you find.

its just the vent for the tranny... 100% positive.. but i dont know were it plugs into top of the tranny.. guess ill have to take a mirror and look...but for the op its just the vent... and should be bolted to the top left bolt of transmission to engine....
