Default 4L80e o-ring location

I just assembled the pump and for this trans and noticed this o-ring on the bench. There is a new one in my kit so it has to go somewhere, but for the life of me I'm not sure where. I went through the astg manual and it didn't jump out at me. Doesn't help that I took this apart over a year ago haha. Who can help me out?

It looks like a combination of a round o-ring and flat rubber washer if that makes sense.

O ring for the pressure manifold. Should be more than 1 in the seal kit.
