Need help

I’m trying to figure out where the leak is coming from. The small plate circled moves and I’m not sure if it is supposed to. What is this plate called and has anyone had a similar issue? Thanks for your time

 

that is just an inspection cover. most likely is is a rear main seal for a shaft seal for the torque converter. possible trans pump seal if it bolts in from the front. you will need to remove the trans to find out for sure.

 

My moneys on Rear Main seal. Mine looked like that. I replaced mine at home no more leakin

 

How hard was that to do?

I was replacing my cracked flex plate.

Did it all at home with no help. Removing the trans is the hardest part.
