Have them update the PCM to the latest calibration using IDS version 74.02 (this is the current latest version), clear the adaptive tables and perform an adaptive drive cycle. If they tell you they cannot do this, inform them that verifying that the PCM is at the latest calibration is a part of base transmission diagnosis
The transmission will behave based on driving conditions and driver input. If the vehicle tows a trailer or is driven aggressively, this will cause it to shift harsh
