Assembly Replacement Process for Service Agents with Regional Empowerment Level
Service Agents with Regional Empowerment Level are not required to contact the PQC for CNG, LPG or gasoline engine, Duramax® diesel engine,
transmission and/or transfer case replacement authorization. Service Agents are still required to contact the PQC for any current restrictions or exchanges.

Service Management Determines Assembly Repair or Replacement
The Service Manager has the authority and the responsibility to make the decision regarding repairing or replacing the assembly.
It is still required that the Service Manager examine both alternatives and make the best decision for the customer, while keeping expense management in-line.
The past performance of the Service Agent has provided this empowerment within the Global Warranty Management system and your future performance will
impact the retention of this enhanced empowerment.
It is required that all engine, transmission and/or transfer case assemblies with core charges are retained for 1 day after the Transaction has been paid.
Components without core charges that have not been requested to be returned by the WPC must be retained as outlined in the Service Policies and Procedure
Manual. Any assembly that is replaced may need to be returned to the WPC for review.

occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
