Make sure it does not have an engine miss.

In the event that it does not have an engine miss, have it rebuilt by a shop that has someone who has full knowledge of all of the fixes that Sonnax has for that transmission, and will install them correctly. Have the converter rebuilt by ACI in Old Hickory TN, just outside of Nashville.
