I wish it was cheap enough to fly me over and replace the transmission for you. Saab is a bit odd with some of their stuff, but the bones are not too hard to work on. 

A good used transmission should be easy to find. Definitely take care of other things like the main seals in the area while everything is apart. (Rear main, output shaft seals, dipstick o-ring is often forgotten if it has one)  

 I wish in general if it would be easier to travel and buy from US...
Despite all the shit you have still so much cheaper many many things. But of course we basically live in 19. century merkantilism, so it can't be allowed to purchase cheaper things from abroad.  

 Yes,that is true.
