I know this is a long delayed reply, but thanks for all of the advice/posts everyone. As many mentioned, the leak was in fact from the top of the transmission -- specifically, there was a small tear in the rubber seal on the top of the base of the shifter (located below both the outer and inner shift boots). I'm going to have to either buy a whole new shifter assembly or perhaps get a replacement seal from the local stealership.
In case anyone else runs into this problem or need to replace the inner shift boot (which in my case was collaterally damaged due to the shifter seal leak spraying tranny fluid onto the underside of the inner shift boot leading to the rubber turning into a gooey hole), the ONLY place I've been able to find a replacement part is here: Jeeps Are Us
(warning -- some other members on the forum have had issues with buying from them)
