I have a antifreeze leak and i can see it drip between the transmission and oil pans, i can't see where its coming from, awhile ago i put in new heater core all new hoses, heater control valve and radiator. Worked fine until recently, but i can't see where it's leaking from??!!

 

There are 2 freeze plugs in between the engine and the trans.

I would make sure that its not just a hose or the rear of the intake leaking and running down the back of the block before I went and pulled the trans to get to the freeze plugs.

Check all other hoese, etc. for any leaks.

Eliminate all other possibilties before pulling the trans to get them.

 

I had the same problem, couldn't see where is was coming from due to the wind blowing the coolant everywhere from driving. Turned out to be the freeze plug behind the starter. It had corroded through and was leaking a little at a time, and only when the system was pressurized. Go get a pressure tester from Auto Zone and see where it is leaking from when under pressure. If its the freeze plug let me know and I tell you what to do from there.
