It's a "Grand Wagoneer"

A leaking transmission pan gasket. Very minor leak (drop every 3 minutes while parked). Not coming from anywhere else. Plan on temporarily sealing it with a tire plug and "gluing" the plug in place with Ultra Black from Permatex. Does this sound viable?

It's the gasket. I've cleaned everything else around it, including the throttle linkage, etc above the pan (on that side). I have nothing off the lines, filler tube or housing, and only the items rear of it get wet (the cross member and a little ways down the underside). I cleaned it w/ brake cleaner, and afterwards (several minutes later) it will again eventually start leaking (dripping) from the rear corner w/o being carried from anywhere else. As I responded to a previous (inadvertent double-post), I don't have the money and I'm prohibited from working on a vehicle where I live. I know the pan removal is the way, but I'm just looking for a "quick fix".
