Gents,
I am reinstalling my bathroom and getting to work on the plumbing; waste part first. At the junction where the 2" male piece fits into the actual black tank fitting(2" female) through the floor, there is a fair amount of slop. I felt inside the female fitting and it feels as though there is groove for an o-ring. I suspect you aren't meant to glue this piece so it can be removed later if necessary so it makes sense an o-ring would be utilized. I noticed when I pulled it out the PO just had it smothered in silicone.
My question is; assuming I just need an o-ring, is it some sort of specialty o-ring or any department store jobber will do? Or am i simply wrong about how these fittings go together?
Thanks.

You are correct that GM used a slip fitting. Bad idea!
Even if you get it back to factory install condition it will still leak in the future.
Here is how I solved the problem years back.

On the other side of the holding tank is the kitchen drain fitting. It also needed revising.

Here is how I did it:
