Auto Trans leak on 07 JK

I noticed that there is a small (minor) leak on the driver side of my trans. I removed the trans armor to locate the leak. No luck. There are three I think electrical connections on the driver's side that could seep or leak. Or, it could be the pan gasket. It is not a big deal. I guess I just don't like leaks of any kind. Anyone have a similar situation?

Recall J30 covers the cooling and I think also the leaking lines-it's probably coming from the rubber vibration isolators, at the "gap' between the line ends and the radiator side--just pop hood and look straight down, the bottom line is usually the culprit and thats the "hot oil" tranny exit line--you can't fixit unless you're willing to cut the complete isolator line out and attach NEW tranny oil rubber lines--the elec conns are leaking only because the fluid has gathered there--

Call dealer !

Thanks Jimbox. I just went out and taped some absorbent pads above the pan, near the coolant lines and electrical connections. I also taped around the pan gasket. I should have the leak isolated in a day or two. I hope it is the pan gasket. I am at 36K miles and I guess a tranny fluid change wouldn't hurt. Thanks again.

You're welcome dr. if you're gonna do the flush yourself--readup on whats required for that 42rle-

If you're gonna try to fix the rubber isolator conn's, nows the time to add an aux cooler !

Jimbox: Found the leak. Pan gasket. Jeep parts guy said they don't sell a gasket for the auto trans. They use RTV only. Not sure I buy that. Autozone has a gasket, so I think I will use it plus the RTV as you suggested. Thanks again for the advice.

I think you better double check the pan removal/replace and especially bolt #5--

I've never doneit, but if your removing the pan-you gotta do a flush and filter replacement--!!!!!

One guy on this forum has doneit and has the thread with info, but I don't remember who--search--

Good luck
