Yep as atmsmshr says the plug is totally sealed from the fluid.
the cone on the conductor plate has the pins sealed in the bottom of it, no fluid can get in from the back of the pins. when you push in the connector tube it has holes in the bottom that the pins slide through but it seals - using the first o ring - to the inside of the cone on the connector plate.
The second ring on the connector tube seals the tube to the transmission casing so the fluid cannot leak out through that joint.
that means that once the screw in the center of the connector tube is tightened no fluid can get into the connector unless the o ring leaks. Its actually possible to get the 2nd o ring leaking and get a leak from the transmission but not into the plug. Similarly if the 2nd o ring doesn't leak but the first does you can get a leak into the plug but not around the transmission. If the male oring is good at that point it will only leak up the wires of from the wire bundle.
