I ordered new trans cooler lines for my '06. Has anyone replaced these before? The service manager at the dealer warned me that they are "a real *****" to replace, and that a special tool is needed for the connections. Any advice is appreciated.

Just depends on how you want to install it. If you want, just cut the lines going to the current ****** cooler and hook in series with it. Grab some barbs and clamps and call it a day.

I'm not adding a cooler. I'm replacing the stock cooler lines.

why are you doing this?
are you having problems with your current lines?
just replacing 3 year old parts for the sake of doing it is asking for work
if you like work that much...
my yard needs mowing
my Jeeps need a good cleaning
the trans fluid on the TJ should be changed ,wont hurt to change the KJ while you are at it
I need the north side of my house washed ,green slime on it
I need to get some crown molding up in my living room
if this is not enough to keep you busy I can think of more
Just kidding

There not real hard to replace if doing on a lift but will be a pain doing on the ground.

Thanks for the reply. I talked to a Chrysler-Jeep mechanic I know. He said pretty much the same, that it would be very difficult to position the lines without having it on a lift. Guess I'll have to take it in.

There is no way to splice in transmission hose? I looked at mine, and if the metal lines went bad, I would just splice in some hose, unless the fittings/connectors AT the transmission were bad. Just wondering, why exactly, you need to replace the entire deal there...

I was also wondering that. If some connections went bad I would just cut them out and put some hoses in. Excellent time to put in a bigger cooler also.

The mechanic I talked to (who I know and trust) said that he wouldn't do that because of the pressure in the lines.

dude
you still have not answered why you are going through all this
second I have at least 1 splice and both the connectors for my cooler are barb fittings
thinking about it
all my rubber lines are connected with hose clamps on each end
1 has a splice and I have no leaks

When the vehicle is off there is zero pressure in the trans cooler lines since the engine needs to be running for the trans pump to work.

Um, right. He was talking about when the vehicle is running.

Just a little bored, I guess. I thought about rebuilding the engine, or maybe swapping in a warmed-over 360 I have laying around, but that seemed more like a weekend project. This seemed more like a lunch-hour type project.

But no, no problems with the current lines...they're pristine. :D

There is not so much pressure that a splice won't work. If you can, you can flange out the ends and use the hoses. There is a tool you can put into the metal tube, and flair it out so the band-clamp works better. LOTS of people have replaced their OEM metal lines with just hose, and you you would have to, to ADD another cooler anyway...

Dude, why do you think? For fun? One of the lines is leaking at both crimps.



The easy fix is
remove dinky crimps ,if they are the ones that you take off by squeezing
replace rubber line with new rubber line
replace crimps with GOOD QUALITY hose clamps
*note buy extra line and some extra clamps and a barb type line splice keep the line and clamps in a zip lock bag if you ever bust a trans line you can fix it in 2 minutes

if they are the ones that have the steel clamped around them via a machine
you can
cut the hard line
flair end just a little with a flair tool
buy new rubber line ,clamps, ect.
slide the rubber line down past the flair enough so the clamp is on the back side of the flair ,the clamp can keep the line from leaking and with the flair it will not come off
or
get a compression fitting to an npt fitting
get a barb to npt fitting
and install with new rubber line
cut hard lines and install compression fitting
install barb fitting to compression fitting
use new rubber hose
all of these are 10X easier than replacing the OE lines

OK, guys, this thread is derailed worse than a freight train. Yes, I've flaired steel lines, etc, etc. My original question was:

I ordered new trans cooler lines for my '06. Has anyone replaced these before?

It appears that only tjkj has. Thanks for the replies, now let's put this poor thread out of it's misery.
