At that point I realized I really need to learn more about what I'm looking at to know what I am even doing.

I've tried several times to identify the PCM under there, but I really don't know what I'm looking for. I've googled pictures to help me, but no luck. I really need to get a service repair manual, but they're quite expensive and we're just struggling to find two nickles to rub together these days.

The trans still slips, but only once every several drives. But when it does slip, it slips all over. And I guess to be clear, perhaps it's not the trans slipping, perhaps it's just losing power sporatically, I'm not sure I can really tell the difference.

4 different mechanics have looked into this and have come up with nothing, I don't know why I thought I'd be able to do any different...
I know its not the answer to all of your questions, but the PCM is pretty easy to find. Just go to the passenger side fender and open the hood. It sits under the black plastic windshield wiper cowl. There is a rather large connector going into it. That connector has probably 100+wires and is large and rectangular. 80-90% of the PCM resides behind the firewall. The only part you can see is the front of it and the connector.
