You can get a "partial rebuild" SVX transmission from me for $999. They are upgraded to shift lightning fast, increase the torque holding capacity of the clutch packs which fail so they don't fail again, and increase the lubrication and cooling of the rear support thrust bearing so it doesn't fail. You'll also need to replace your atf cooler with a high capacity aftermarket unit--preferably mounted in the drivers fender with it's own fan, thermostat, and relay.
After that you'll have twice the car and never have to worry about your transmission again.
