Yes, found the leak, and the connector is loose, can wiggle a few mm. Now, can I get rid of that leak without removing the pan? Can I just pull it out and put an o-ring on? What's on the other side, will I pull something apart on the inside?

Kickdown works fine, it's just the leak...

 

No, had to drop pan to get it out, new o-ring, some sealer, pushed back in, pan on
