Easy solution... don't accept the 'run around'. Demand that he give you a definite schedule for completion. Also, I assume that you have a written estimate for the second repair. If not, get one before authorizing any expenses!!!
However, your post is a little confusing...
Was the transmission 'repaired' or 'replaced'? From the price (and without knowin model or location), it sounds like either a repair or install a used transmission. Either way, the Torgue Converter would probably NOT be a part of the original repair (especially for that price). If so, you will probably have to pay for the second (separate) repair. I might suggest that if you feel the two ARE related, call some other tranny shops. Ask them about the correlation, if any, the torque convertor has to the original repair. If they feel there is a connection, get them to confirm their opinion in writing, then consider suing the first tranny shop in small claims.
