Leaking cooler lines (drip up front), leaking front pump seal (drip off
the bell housing front edge), servo leak (drips off the side) or
overfilled and running out the vent (also down one side, but obviously
from the top of the tranny).
Most likely front seal or cooler lines.
I would also check the vacuum modulator line, they have been known to
leak and cause fluid to be pulled into the vac pump -- this will cause
serious deterioration of the vac line rubber connectors and fill the
crankcase with tranny fluid -- have you been " making" engine oil?
