Delete all of your error codes via the stomp test or by unplugging your ecu for a few minutes, and then try again.

Make sure that your throttle position sensor is working fine. Its a little sensor connection right next to the throttle body's O opening. Unplug it, clean it and the sensor with contact cleaner, dap dielectric grease on both and plug that back. That can sometimes cause issues with shifting.

Please download the bentley manual and go through the tranny troubleshooting summary there as well for suspects, google for the links.
