2012 Auto? MUST READ-Trans line rub causes leaks!

My 2012 JKU had a major transmission line leak at 5,000 miles.

The tech said it was due to power steering line rubbing against the transmission line behind the drivers side wheel well. When he installed the new trans line he bent it away from the power steering line and applied some foam to protect it. He said had he installed it stock it would have likely rubbed through again. (Service report is below)

Below are pictures of where the leak occurs (according to my internet search this is becoming all too common on the new 2012 autos)

One picture is of the differential cover paint which was taken off from the hot trans fluid leak. (picture is upside down)

I checked the four 2012 autos on the dealer lot and 2 out of 4 were touching and will likely rub together and in my opinion may leak as well! :doh:

So check your lines and make sure they are not touching. If they are, you might want to talk to a service tech to see i they can prevent a leak.:thumbsup:

Good to hear people are aware of the problem now. I hope the foam works well make sure he foam is dense enough that any rubbing won't tear the foam and put you bAck into the same space.

Just checked mine and it had rubbed a nice flat spot on the transmission line in 2,600 miles. Thanks for the info. This saved me some grief down the road!
Bummer. I'm glad you caught this.

I hope this thread not being near the top continues and this is not a big issue for others.

I just checked mine...manufactured in October, 2012. There is already a thick rubber sleeve going all the way around that bend so it is apparently something they caught mid-year.

And where are you getting that information? I doubt that it is correct. They are recalling about 220,000 Wranglers worldwide...sales are somewhere approaching 200,000/year. From what I discovered on mine, it appears that only 2013 models manufactured before a certain date would be recalled. Mine has the sleeve and was produced last October.

Yes go right in. It may all dump out in a matter if days if it is oozing. You don't want that. I had that. Not sure if Jeep is redesigning the lines but perhaps that is why it isn't happening until July but my service tech just rebent the replacement lines to clear each other then reinforced with foam to protect some.

I believe it is autos only but don't quote me.

That rubber hose looks like a great prevention fix if the lines are close-
Just a word of caution for other Jeepers- be sure that any rubbing didn't already weaken the lines. Since there is a recall it would be best to have it checked out and fixed. I read someplace that several Jeepers had lines close to worn through but just not yet.

So there is a recall. I was notified in July that they knew of the problem. In October they mailed another notice for me to make an appt. to have the work done. Today I called and my dealer said there are order restrictions of I e part per two weeks and I can't get mine repaired until NOVEMBER 2014!!! What the hell Jeep?!?!

I guess I'm lucky Because I think the tech that services my leak last year fixed it well enough that I don't expect to have a problem but still. Think of all those jeeps with rubbing hoses. When your talking hot transmission fluid leaks up there I would think your looking at a fire risk aren't you?
