Front trans. seal usualy leaks more when the motor is off, because the converter sags when it's not rotating. I think this is why the front seal leaks more in cars that don't get much drive time. The seal gets deformed and dosn't seal correctly.

The large puddle may be from oil that pooled up on the engine cover and once it reached a point were it began to drip it siphoned the pool of oil off the cover.
