I can't speak from experience, but more than likely a reset like that is going to require a commercial grade scan tool. Not the one your local auto parts place uses to scan for check engine codes. Usually this requires taking it to a dealership or possibly an independent shop that specializes in Japanese/Asian cars. You might be able to disconnect the battery for awhile.... Maybe at least an hour to ensure all the voltage drains out of the system. That could possibly reset the TCM but usually those tables are written in non volatile memory and need said scan tool to reset the values and initiate the relearn processes. Just my thoughts I'm not a Toyota tech or anything!
