"All the modules on the GMLAN networks maintain a transmit error counter (TEC). The counter values increase with detected errors and will decrease with error-free messages. If the TEC value exceeds 255, the controller removes itself from the network and DTC U0073 will result."

Essentially, you have to test every device on the GMLAN to find the one setting the error. The '06 manual lists the ECM, Radio, and Remote Control Door Lock Receiver as the modules which can set that code, but your '08 may have a longer list.
