Service Agents Not Required to Contact
the PQC for CNG, LPG or Gasoline
Engine, Transmission and/or Transfer
Case Replacement Authorization
You are no longer required to contact the PQC and are
not required to have a pre-authorization to either repair
or replace an engine, transmission and/or transfer
case. The Service Manager has the authority and the
responsibility to make the decision regarding either
repairing or replacing these assemblies.
It is still required that you examine both alternatives and
make the best decision for the customer, while keeping
expense management in-line. Your past performance
has given you this additional empowerment within the
Global Warranty Management system and your future
performance will impact the retention of this enhanced
empowerment.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may 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.
