Default 4L60E Leak

My 98 TA was stored for winter and not run for 4 months. The entire time I noticed no leaks, but when I took it out this weekend there was a wet spot of trans fluid under the car. It must have started recently while sitting. Only the front 1/3 of the pan is wet with a couple of drips on it. When the car was running, nothing leaked, so I took it for a drive, and I saw no drips afterward or while it was still running. However after sitting all night, it leaked a little more overnight leaving a small spot on the floor and a couple more drips on the front edge of the pan. Any ideas?

After searching I figure it could be 3 things...the pan gasket, the front seal, or the pump gasket/o-rings. Would the front seal or pump seals cause it to leak while running, not just while sitting?

It it leaks only while sitting (engine off) then it might possibly be the fill tube seal... or the pan gasket.
