Well part of the problem is that the dealer told me they are getting blank codes when they run their diagnostic. They are telling me that the valve body is not sending any fault codes to the computer and so they had to test it manually. I was hoping to get the codes and have an independent shop tell me if the issue could be remedied any other way, but they did tell me that it was an electrical issue and this sounds like it could possibly be the cause.
Is there any way to tell if it is a 5 or 7 speed transmission? Also is there any way to check one way or the other whether the problem is the valve body or the electical plate?
If you wouldn't mind PM'ing me I could use some over the phone help as this is a $2500+ repair job as it stands now and I could use a little bit of help with understanding how to find the problem and what to ask them.
Really appreciate the suggestion either way though.

I would try that with a new filter, fluid and conduit before tossing an expensive valve body on it.
but if you can get the fault codes from the dealer, that would also help with diagnosis
