John was on the phone with Sam @ GTM for a long time. They even had a screen sharing program so Sam could see the complications. (Sam, please fill in what I am misinforming?)
Jimmy thinks it may be an immobilized lockout, and he's asked me if I had any concerns when working the connectors in the trans. No, I didn't, but I am open for any possibility.
So, to any tuners out there: has this ever occurred on your builds?
Jimmy may take it to the dealer, to plug in their computer.
We are all stumped, and paralyzed right now. That's the scoop.

What ever your experiencing is very unusual, I left uprev couple messages yesterday to establish couple points with them to see what prompt them to ask for the ecu. usually the ecu never has to leave the car for any of this, also sense the dealer was unable to communicate with the ecu this will leaves with two possibilities, it is either the ecu is toast or there is something is not connected in the car.
I would recommend going over the car very very thoroughly and if the comeback empty handed i would resend the ecu back to uprev so the can flash back to stock . and see id the car will run after that .
Sorry about your trouble .
Sam
