The Nissan Path

So I have a small atf leak. It’s dripping on the passenger side. About halfway back on the car. About at the level of the muffler. Is there anything right there that can be leaking? From under the car I can see a small what looks like a heat shield? It’s kind of triangle shaped and says left on it and looks like it’s secured by 3 bolts or so. Up under it is several hard lines running towards the back. Do any of those carry atf to the rear and could they be leaking? Any ideas? I just changed the atf fluid of this helps?

Ok....so after doing some more research it seems like this is probably the turbine speed sensor leaking. Has anyone had any success in doing anything about this problem short of replacing the sensor? The car has 216000 miles on it and I can’t justify that expense for a repair. I have a feeling this is causing my o2 sensor errors as well since the passenger secondary sensor has oil on it. I’m hoping somebody has done something
