You mentioned there is a number that shows up if you delay the shift. What is the number?
Also, because this is a newer vehicle, I strongly recommend having the can-bus scanned for diagnostic trouble codes.
CAN stands for controller area network. Basically, the different modules are tied together via a few wires. If there is a code stored, this will retrieve it.
Here is a link that shows how it's done:
Let me know what the number is and if you can have that type of scan done.
