This is something that can be figured out but it is easier to use the transmission simulator laid out in this test. However, if it were me I would let them figure it out. Just be mindful that they are probably going to try to say there is nothing wrong and give it back due to the code being pending.
Here is the test that would need to be completed. The theory of operation is pretty good at describing what is going on. Let me know if you have questions.
