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)





This 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!

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.

That's crazy. They had a problem with the fender on the 07-11

Wow thanks so much for documenting it all and working on those pictures. That takes a lot of effort, thanks. I'll have to check mine soon before my move from Ohio to Texas.

I've got a 12 Rubi 2dr. Looks nothing like this at all. 2-12 build date.

Thanks for the heads up Fly...As for the 07-'11s, yup the fender had to be trimmed because the brake line would rub....

Is yours an automatic transmission?

Did you pull back the plastic under the wheel well on drivers side?

If yes on both, please post pics.

As I understand it my leak was at two places- at the entry into the radiator and on the line- so as long as they are not rubbing then I would think you should be good.

It's an auto. I look at it very close, pulled back the fender well, really mines not the same, they don't come within 2 inches of any other lines.

Try to get pics, within 2 hrs maybe.
