PK'S XJ

My transmission cooler line is leaking at the poorly engineered joint where the hard line from the cooler meets the soft line going to the transmission. I have seen many ideas but thinking the best is pulling out the hard line....cutting off the soft line coupleer...inserting the hard line into the soft line and clamping down with two hose clamps. The hard line does have a flare in it so I think this may work. Anybody have any better ideas???

Sounds like a similar problem I have, however mine doesn't leak all that much so I just keep checking it and adding as needed. Possible for a picture and I'll see if it's close to mine? (and if it is I was thinking of the same solution you had)

As long as the hard line has a flare in it, thats what I'd do. I've done it quite a few times actually. Just be sure not to overtighten the clamps

Ok--I have attached a couple pics. It is leaking a quart a week so it must be done. I am going to try later today to fix it. I will take step by step pics as I go. Maybe it will help someone with the same problem??? Let me know what you think?? I just dont understand why this line has a disconnect in it anyway. Thanks for the input.

Thanks for the input. I put up a couple of pics. I am going to give the repair a whirl this afternoon.

Whatever happened with this? Did you end up scrapping the disconnects and placing hose clamps on? I have the same problem except its not leaking its gushing at this point!

Yeah.

Anyone have anymore info on this.

I was thinking about doing something like this and doing an external cooler.

Any thoughts. Best route for the late model XJ's?

I've never seen anything like that before. Has anyone used one of these in this spot?

The cooler runs at a low enough pressure that it's not a huge concern to just slip the soft line over the hard. If you are worried flare the end of the hard line.

theymake a tool that remove the line itjust has an oring in there replace it snap it together simple

Its been awhile, but mine is leaking as well. But mine is coming from the very front of the line near the radiator. Is this the same line? I can see the line up in my driver side fender well.

Mine has a hardline, to rubber, then back to hard line all the way back?

Sorry, it might be a stupid question, but i must ask.

Thx

Old thread, common problem, good info. I fixed two leaking trans lines by cutting the hard lines, flaring the ends and installing new line with hose clamps on one, and just cutting the fitting off the other to create a fresh rubber hose end, which I clamped.

Cutting the hard line:



This is the end of the hard line on the radiator side after the factory disconnect is removed. I tried to push the new hose over this, but couldn't get it far enough for a clamp to seat past the existing "flare", so I ended up flaring the end:



New hose clamped over flared ends:






The clamp on the right in the photo is in place of the leaking stock pressed fitting, using the existing stock hose:



My previously repaired and now removed leaking stock trans cooler hose section:

Good job using a tubing cutter for this. Folks, do NOT use a saw of any kind! You'll make little tiny transmission destroyers and put them into your cooler line. Not good.

No need to flare the line, though. Just clamp it.

There isn't enough pressure on those lines to worry about.

If you are worried, use two clamps. If you don't have enough hose, just add a section. Make sure you get something rated for transmission line.
