That plus the bolts that are "single use" items involved in splitting the cases and you should be up ad running assuming there's no other damage. All in, about $400 in gaskets, bolts, and transmission parts.
Not that bad and not worth taking the risk putting in used parts imho, when new parts aren't all that terribly priced. The labor is the killer.
