Hi peedee, thanks for responding. An o-ring that has hardened and flattened? Hmmm.......didn't think of that. Well.....I had no choice but to reuse the old seal and when I put the Mercon V fluid in, I noticed it was leaking from that seal when I was installing the pump to the block. Pretty disappointing.
Last night I decided to use Aisin FIPG (Formed In Place Gasket) which is a black, oil-resistant RTV that Toyota and some other makes use. Too bad, because FIPG can be a real pain to clean up if you have to take it apart. I kept the old seal in there and smeared a thin layer of FIPG on the mating surface and tightened it down (never could find the torque spec for that). I plan on installing the pump tonight or tomorrow night. I should have tried to find an oil-resistant o-ring, but honestly it looks like a nylon crush washer, so I discounted that idea. Hopefully the FIPG will seal it up. If not, I'll have to clean it up and try to find a fat oil-resistant o-ring that fits perfectly in there. That could be hard to find. Thanks for bringing the possibility that it was an o-ring to my attention.
