for the following components:
• Current parts restriction on the Allison
transmission.
• Current parts restriction on the Duramax ® diesel
engine — RPO LGH or LML.
• Any component listed in a current parts restriction.

The Service Department Personnel should review the
applicable documents related to the Part Restriction or
Exchange Program and be prepared to provide
diagnostic information.
Customer Satisfaction
There may be situations where an assembly can be
repaired, but due to customer satisfaction reasons an
assembly replacement should be considered. In these
cases the service department personnel should review
the concern with the District Manager Aftersales
(DMA), in Canada the District Manager - Customer
Care and Service Process (DM-CCSP).
For Service Agents required to contact the PQC, the
service department personnel MUST be prepared to
provide diagnostic information as well as a completed
repair/replacement estimate portion of the PQC Cost
Comparison Worksheet. Service Agents required to
contact the PQC, MUST advise the PQC when the
DMA, in Canada the DM-CCSP authorizes the
replacement of an engine, transmission or transfer
case assembly for Customer Enthusiasm purposes
versus repair.
Service Agents Working With PCC (United
States Only)
All Service Agents that are working with the PCC to
reimburse Independent Service Centers (ISC) must
continue to follow the existing PCC processes.

PQC Process
Before Calling PQC
If diagnosis performed by the service department
personnel indicates a need for an engine, transmission
or transfer case assembly replacement, Service Agents
required to call PQC must perform the following actions
PRIOR to replacement and BEFORE
contacting PQC:
• Complete the Calibration Verification Number
process as outlined in the latest version of:
– Corporate Bulletin #14-06-04-003: Identifying
Non-GM ECM Calibration Use and Power-up
Hardware Detection in Duramax Diesel Engines
Using GDS 2
– Corporate Bulletin #08-06-04-006 for Duramax ®
Diesel Engines
– Corporate Bulletin #09-06-04-026 for Gasoline
Engines / Transmissions
• For automatic transmissions only, perform a
transmission cooler flush and record the code.
• The Condition and Cause including any diagnostic
trouble codes (DTCs), symptoms, Scan Tool
Snapshots and any other useful information
observed and recorded by the technician. The
technician must have detailed information
required for proper root cause analysis and
product concerns correction. This information is
very valuable in ensuring that the replacement
assemblies and current production parts help to
continually improve our products.
• Record the serial number of the failed assembly.
• Complete a PQC Cost Comparison Worksheet.
For help in locating this form, see the following
section titled: PQC Cost Comparison Worksheet
On Global Connect (U.S.)
• Complete the Repair Estimate and Replacement
Component Assembly Estimate for the assembly
category included in the PQC Cost Comparison
Worksheet. Accurate repair versus replacement
cost estimates (include the markups) are
ESSENTIAL in order to eliminate a second call to
the PQC.
• Have the repair order number, VIN and your BAC
code ready when calling the PQC along with a
detailed Customer Concern.
We are requesting that ALL service technicians use
this opportunity to help GM better understand how and
why a given component failed. For GM this is an
opportunity to have direct and thorough feedback from
the technician to provide to Engineering and thus
improve the reliability and durability of both OEM and
Genuine GM Parts assemblies.
