Anyone knows what is this part Circled in yellow? I noticed it has a bit of oil when I was putting the plastic cover after replacing the lower control arm.

Thanks everyone.

These are a plugs for a Torque Converter Port,

in case you want to be sure if Converter has leak or not, just unplug one of them...

Any idea what this is?-t-q-plugs.jpg

I need to trace it again. Majority that seems like caused by rear main seal based on what I searched on google. If so, then it's going to be expensive cuz transmission needs to be removed in order to replace the seal. What's usually cause the leak? is this typical?
