It comes out between the tourque converter and the transmission. Do you not know how this is set up? Crankshaft is connected to fly wheel, fly wheel connected to the torque converter, converter rides on a shaft coming out of the trans mission (input shaft) and the seal is in between the trans case and the converter. This is all inclosed with in the "bell housing" on auto trans is actullay part of the trans case.. There are a series of vents You will only be able to look through to see if the the fluid is coming down between the trans case and the converter.
To specifically answer your question, toward the front of the trans ,out the bottem of the vents.
But honestly, Its more than likly you would need an entire reseal of your trans. Trans leaks can be trick to find some times, I know . There is several places I have seen them leak.
