OK. I'll play.
Thanks for responding. My question was asked as such to inquire of those that may have purchased a "transmission seal kit" that includes the above mentioned seals, (apparently an exterior seal kit). I thought this kit would be kind of like an engine seal kit that would provide all the seals needed to seal the transmission. This kit seems to provide a minimal amount of seals, and no seal that would be responsible for the tranny/diff fluid exchange problem.
A person having purchased said kit or replaced the problematic seal(s) may know what I am talking about and offer an opinion about their experience. Maybe not.
It seemed odd to me that a "transmission seal kit" would include only exterior type seals (ie the seals that only require removal of covers (governer and 2nd gear plunger) and some external components (2nd gear plunger, governer, pan) as well the gasket and o-ring for the seperation of the tranny and diff (though not the main shaft seal twixt the two), and not the apparent plethora of seals inside the transmission and differential. Changing these exterior seals may be helpful, or may just be potentially opening another can of worms if one is not prepared to handle the entire rebuild (something I was hoping to avoid). Some of the seals in the transmission and differential require entire dissassembly of the tranny and diff to replace. These seals are not in the kit I have. As well, the friction pads and steel plates are not included which I expected as I wasn't planning on rebuilding, just sealing. I was surprized that the seal kit seemed so light on seals and didn't seem to have the seal(s) for the fluid exchange.
I was hoping that someone would know which particular seal, if it is in fact one, that causes the leakage from the transmission to the differential. This way I would not necessarily have to dissassemble to explore for hard, cracked seals (that likely should be replaced after opening a 20 year old piece of machinery anyway).

That's what I thought would be recommended.
So, since it appears that I will be dissassembling the tranny and differential to change all the seals (that may come in a "master transmission rebuild kit" or may not.)
I am pondering if I should then consider reinstalling the transmission that I thought was dying (that actually may have been the worn cam lobe making the engine operate on only two cylinders and not have been transmission issues at all...), while I source parts and learn how to rebuild a transmission. I may find that the old transmission is fine and will carry me through this camping season while I work on the new transmission. If not, I'll park it and do the rebuild right away. Then when the tranny is rebuilt, swap it out.
Removal of the tranny with the engine in does not appear to be too difficult, so a future swap may not be too bad.
Or just consider that this next camping season may be out while I do a complete transmisison rebuild. I am of the 'If it aint broke, don't fixit" mindset. Cursery inspection of the 'New Tranny', does not indicate leakage or fluid contamination in the diff.
I am concerned that I can get started on rebuilding the transmission and hit a dead-end with part sourcing.
