Recurring transmission fluid leak issue....

I've found the useful posts about transmission fluid leaks tied to a faulty O-ring and/or replacement adaptor plug for the wiring harness (adapter plug P/N 68021352AA).

NEEDED: Can somebody assist with where/how to view the adaptor plug to look for leaking fluid? What is the best way to see the adaptor? Is it visible without a lift and/or is there a viewing angle to see it directly? Pictures would be greatly appreciated if there's a way to see it without disassembling things.

History:
I've had my 2010 in for its routine tranny filter/fluid/pan gasket replacement at the dealer.

A few months after that work, I found that the transmission was leaking fluid and it would slip between shifts from 1 to 2.

During an alternator replacement at a different shop, I asked them to take a look...they suspected the pan gasket was leaking based on where the tranny fluid was collecting....and they suggested I go back to the dealer that performed the recent work to see if maybe the gasket was pinched or something else going on with the work performed.

I brought it back into the dealer.... This visit resulted in replacing the rear output shaft seal on the transmission, citing that was the source of the leak. Also replaced transmission mount (NAPA part 6202581) during that same visit.

And now... three months later, slipping again between 1 to 2, and I'm researching what others have seen...

So, I need some help to locate the adaptor to look for leaking fluid before taking it back in to the dealership blindly and wanting to make sure they look for the easy solution found by others on this forum.

Thanks all!

If you can get under the Jeep, the plug is on the passenger side of the trans, 3/4 way up the side, near the front of the trans. You should see fluid leaking down the front right side, or it'll look like it's coming from the rear main seal area. It's a pretty common issue. It was a recall on 06/07's. You can find the part for like $10-15 online.

The nag1 transmission has a main fault with o-ring on the input shat in the torque converter there is an o-ring that does perish which allows fluid to leak through onto the pressure plate reducing pressure but this would cause all gears to slip so if not that you would have problems with the valve in your valve body on the second gear the leak on the plug would not cause gear slippage it is some time ago I looked at this in a series of YouTube videos siu automotive a series the do a complete rebuild of a nag1 and the torque converter and show the aftermarket upgrades for the valve body and a Teflon seal in the torque converter instead of the rubber o-ring or your clutch pack is gone on the second gear you need a trans overhaul to diagnose it
