Did they say what came thru? The planatery is probably a planatery diff. But it sounds like there is a couple of problems. You may want to find out about replacing the transmission. It may be cheaper to do that than to spend the time tracing down parts, cleaning, fitting and whatever. I would get the precise list of what they have found and suspect so far and call Terry Haines.
Another thing you could do is call the junk yard here in Leominster Mass, they are a Greenleaf junk yard hich is owned by Ford. Its called ABC Greenleaf. Ask for Cal. Tell him that you have an SVT, are part of a New England club, a bunch of us have come to him in the past and his pricing is real fair - and flexible.
Or you could be really bold and make your car the First SVT Contour with a 6-speed Focus SVT Tranny! I don't know if it would work because of the torque ratings but IIRC the MTX-75 is similar in both.
Good luck and keep us posted.
