not really. You'd need the shifter, a new radiator that includes the tranny cooler, and oil lines from the tranny to the radiator, and a new auto tranny computer/ECU. I don't know if the axle shafts are the same. Plus the tranny, of course. The manual tranny brake master cylinder also includes the master clutch cylinder, so If you were switching from an auto to a manual, then you'd need to replace the master brake cylinder but to go from manual to auto you could probably cap off the clutch part and leave that half unused.
Usually vibers replace their 5 speeds when the bearing noise becomes apparent. If yours is past that to the point where none of the gears work, then it must be really trashed inside, and a rebuild would be way more expensive than a replace.
since you have two threads on this topic, I'll post the link to the other one as a cross reference
