I need help!

I have found a leak coming from the transaxle housing. It is coming from where a line from what I am sure either going to or coming from the cooler into the front of the housing.

I have searched everywhere for a diagram showing the front (I have seen one that shows the side on google) or a part #, I have even looked in my Haynes manual. and nothing. I have been all over this site, as well as "Toronto mazda 3 owners".

I never thought to take a picture of it I never thought it would be easy to find out.

Any help thanks

 

Forgot to add.

It is a 06 mazda 3 2.3l
