When I was evaluating what to do with my blown AT I got these quotes:

New Jasper transmission + installation labor: $3100 (included 3 year warranty IIRC)
Complete rebuild + removal/installation labor: $2200 (included 1 year warranty IIRC)
Transmission swap (removal/installation labor): $800 (no warranty)

Keep in mind these estimates were from a shop in rural NC. Your price may (will) vary.
