Kubota B20 transmission fluid leak?

[aplinm]

I am all new to this..granted I am having a blast with my toy. My question is...parked the tractor in the garge yesterday...after a couple of minutes I noticed 3-4 fairly large drips directly under the transmission casing..It's not oil...fluid is yellowish...getting under the tractor, I noticed small drip points all over the frame, transmission case......I wiped down everything from under and sat there for 15 minutes with no drips, leaks, etc. nothing accumulating from the gasket. An hour later I checked he transmission fluid level...it is over the fill line on the stick...Do I have a problem, or is there some kind of overflow as a result of my transmission fluid level being too full? Next morning only a couple of little drips.
