Mileage is ~340,000miles.

The engine has been replaced at some time during its life but i cant see any indications that the transmission has as well so it may be the original unit.

Understood about the age of the car. I am a "whats the worst case scenario?" guy, so if this is whats needs to be done(replacement) then thats what has to be done. However, I ask because I am not that familliar with this particular transmission and if there is something obvious(or not) that I am missing.... well, I ask.

I will check your link.
