OK so I have a 89 cherokee, I'm in the middle of doing the upgraded cooling system upgrade. (open vs closed system) I'm trying to take off the "quick" disconnects on the transmission line. Lower one came off no problem. Upper one is being a pain in the butt. Any suggestions on an easier way to get it disconnected. I was thinking about just cutting the thing off and hose clamping above the bubble flare on the metal line? Any advice?

 

Not sure about your year but on mine (95), after doing much research I did just that, I cut off the quick disconnects and used new metal tubing and double hose clamped them and have had no problems.

 

I'm not much help. I gather their is a tool for those, google the quick disconnect tool. It pushes in to releve tangs in there I think.

Both of the lines on one of my 90's got mashed, one broken to where the Jeep stopped going up the hill. With a dremmel cutting wheel, I cut out the mashed/lealkng section, and spliced with 3/8 fuel line IIRC. It's not supper high pressure. I DID use two clamps mounted opposite to be on the safe side.

 

IIRC, you can use one of the Ford fuel line disconnect tools.

If you do cut it off, make sure you at least use a flaring kit and flare the tubing end. If not you are asking for it to start leaking.

 

I tried using the fuel line disconnect and it never worked.

There is specific ATF hose, it's rated for higher pressure and ATF fluid compatible, I'd use that. It was $4 at the parts store.

 

What I did was cut the quick disconnect part off and just hope clamped it on the line. I had to but a new metal line between the hose and the radiator. On the line there was a big bubble flare that I clamped above it. Hopefully it stays tight

 

You are likely fine. I don't know the pressure, but I suspect it's only enough to circulate through the Rad. Actually it might help warm up the trans fluid.
