Bulletin No.: 02-07-30-029Z

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 their DMA, in Canada the DM-CCSP.
Service Agents required to contact the PQC must be
prepared to provide diagnostic information as well as a
completed repair/replacement estimate portion of the
Cost Comparison Worksheet for Assembly Repair vs
Replacement. Service Agents required to contact the
PQC, must advise the PQC when the DMA, in Canada
the DM-CCSP or the Brand Quality Manager (BQM)
authorizes the replacement of an engine, transmission
or transfer case assembly for Customer Enthusiasm
purposes vs 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
PQC Inbound-Outbound Email Handling
Dealers that are currently required to contact the PQC
by calling them by phone prior to replacing an
assembly, now have the ability to use the PQC email
address to email them the completed NEW web forms
which are: the Gas Engine, Diesel Engine and
Automatic Transmission Authorization Assembly and
Cost Comparison worksheet and are found in
GlobalConnect under Service Forms.
The following still applies prior to contacting the PQC:
If diagnosis performed by the Service Department
Personnel indicates a need for an engine, transmission
or transfer case assembly replacement, then Service
Agents currently required to contact/call the PQC must
perform the following actions prior to replacement and
before contacting the PQC:
1. 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
2. For automatic transmissions only, perform a

3. Document 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 GM products.
4. Record the serial number of the failed assembly.
5. Complete the: Cost Comparison Worksheet for
Assembly Repair vs Replacement form for the
appropriate assembly category.
6. Complete the: Repair Estimate: Replacement
Component Assembly Estimate: section of the
form. Accurate repair vs replacement cost
estimates (include the markups) are ESSENTIAL
in order to eliminate a second call to the PQC.
7. Have the Job Card number, VIN and the Service
Agent BAC code ready when calling the PQC
along with a detailed Customer Concern.
8. When the engine cannot be repaired, the PQC
requires that .jpg files (pictures) be emailed to the
PQC showing why the engine cannot be repaired
due to extensive cylinder block damage. Also,
when requesting an assembly replacement to
correct a noise condition, Service Personnel
should be prepared to provide a 30 second Sound
file documenting the engine noise.
