I am pretty sure the rear is the return back to the tranny.
Check with others.

That's what I'm thinking mine was too.
Rear = fluid in
Front = fluid out

Yes, the rear fitting had the long "tube" that stuck inside the transmission so the fluid dropped in a specific spot.

Why? IT COMES OUT OF THE FRONT FITTING.
