UPDATE: I just got out from under the car. I dropped the transmission covering tray. The noise is coming from inside the tranny pan. That's not good. I noticed the pan was wet so it will need a gasket and fluid/filter change. Does anyone know how the sucking jet pump works? item 4 on the diagram.

How do you check the fluid level in the DCT tranny. I've looked for write-ups but am striking out. HALP!!
