The dealer should not be taking the transmission apart without diagnosing and getting an understanding of what could be wrong. Mechanical faults that do not occur during driving are not likely to produce any codes.
What you need to do is to simulate the condition to the dealer and see what they have to say about it.
Since vehicle is still under warranty, make sure the complaint is recorded for future reference if required.
