Astro Transmission Leak
The transmission began leaking very badly from this plastic connector. It was almost a quart a day so I had to move quickly. Basically the issue was a bad o-ring seal. Not too bad for lasting 210k miles. The really bad part about this whole thing is that the transmission pan had to be dropped to work on the connector. Wouldn't have been that bad except I had replaced the pan gasket and filter the week before. After replacing the seal, it hasn't leaked.

This was the old seal and you can see the tabs have broken off This is a seal I found at the hardware store
From the bottom with a new seal Since the original tabs were broke, I used two screws to keep it from falling
After two weeks it started leaking again. This is how I finally fixed it
