anyone recognizes this strange part between the oil pan & transmission?
My mechanic told me there is a small oil leak, which he'll fix during next service. He intends to take off the oil pan (maybe I call it by a wrong word) and refit it.

Can the oil pan leak be causing these stains on what I think is transmission box?
