Can you take pictures and post them?

It does have to be split since the flywheel is throwing water, and oil around in the bellhousing. A clutch kit, transmission seals, and rear main seal on the engine should be replaced (might as well while you have it split). In the very bottom of the bellhousing there should be a small hole with a cotter pin sticking out of it (the cotter pin rotates in the hole to keep it open so any oil can drain). I'll bet the cotter pin is missing, and the hole is plugged with dirt.
Are you going to be to keep the old girl under cover? That helps a lot in keeping her fresh.
Make sure you change those boots on top so you don't get anymore water in it and change your fluid too.
I don't think anyone has mentioned this yet, but if you look under the tractor where the bell housing is (under the clutch) you will see a plate that is held on with 4 bolts and in front of that should be a cotter key,,,upside down.... you can take the bolts out and all that stuff will come out and you can look up and see the clutches/pressure plate... I think your trans absorbed a bunch of water over the years and has buoyed the trans/hyd fluid up till it started seeping thru the seal. take that cover off and then drain the trans...hopefully you won't have to split it. who knows?

I 2nd that. Splitting would be a last resort for me
While being left out side with leaky boots over the shift levers can cause water to get into the transhydraulic oil, condensation and non-use or low usage will cause the same thing. SO don't think that leaky shifter boots replacement will cure the problem completely. You have to work the snot out of the tractor occasionally and let the warmed up oil evaporate the water.
