John,
Sorry, I didn't notice if anyone replied or not, so I'll take a stab at it anyway.

Yes, you can replace the TC gasket by lowering the oil pan. It's a pain, but can be done. The hard part is getting the pan gasket to seal properly afterwards.

I've done this successfully; one single time in my life, but might work, if you don't mind the look. Take some brake cleaner and spray the TC gasket thoroughly. Try to get all the oil out. Let it dry for a few minutes. Take your handy-dandy self-reproducing nasty old Ultra-Black silicon, and fill up the outer edges of the TC where it leaks. Smooth it over with your finger for that "almost hilllbilly" look. I successfully sealed up a front seal on the bottom side of a TC like that once. Fortunately, no one could see the work of art that silicone provides. But it worked, no more leak! and only took a few minutes of effort.

However, I've tried a couple of times since then with less success. There's also some other products similar to silicone that advertise 'instant seal' even with oil present to seal up similar oil leaks. Find them near the silicone in your local auto parts store.

Good luck,
Mike
