I replaced the pump and the loud whining sound continue so I replaced the replacement pump with another pump and the sound is still there. What do you think it could be--rack and pinion?

On the back of my transmission where the drive shaft connects, there is a black knob (with wires) that twists into the transmission. Does anyone know what this thing is called? It has a nice leak coming from it and I am assuming that it is a gasket.
