When they modified the software for the transmission, they made a couple of changes specifically for the laser cruise. I don't know what they are, but the dealer needs to take an extra step to update the transmission software. They also have to update software in another computer with a 2005 version. That second update will apply a fix for the laser cruise, but it will also make the main computer generate diagnostic codes based on the 2005 model year. If there is ever a problem in the future, you should use information for 2005 to troubleshoot the codes.
The service bulletin is TC005-03.
