Agree with abeamn7. Also check the o ring around the selector shaft, and pull the converter shield off and look for wetness, pump seals sometimes disguise themselves as pan leaks too.

Another possibility, my pan gasket leaks but only after sitting for several months, the converter drains back and over fills the case.
