CNG, LPG or Gasoline Engine, Transmission and/or Transfer Case Replacement
Process for Service Agents With Regional Empowerment Level
Beginning January 14, 2014, most Service Agents will no longer be required to contact the PQC for CNG, LPG or
gasoline engine, transmission and/or transfer case replacement authorization.
Some Service Agents will still be required to contact the PQC for ALL engine, transmission and/or transfer case
assembly replacement authorizations. Only those Service Agents that are required to contact the PQC, will be
notified by a GlobalConnect message and by their regional representative.

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.
It is required that all engine, transmission and/or transfer case assemblies with core charges are retained for 1 day
after the Warranty 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 Service Policies and Procedure Manual Article 1.7.3. Any
assembly that is replaced may need to be returned to the Warranty Parts Center for review.

Submitting Engine, Transmission and/or Transfer Case Transactions Into Global
Warranty Management — Record Retention
Service Agents MUST complete all of the following Steps 1-5, in order to submit engine, transmission and/or transfer
case warranty Transactions into GWM:
1. Scan the completed Job Card and attach it to the Warranty Transaction in GWM.
Notice: The Warranty Support Center requires that this action is performed on EVERY Warranty Transaction
2. Scan the completed Repair Estimate: Replacement Component Assembly Estimate: worksheet of the
Cost Comparison Worksheet for Assembly Repair vs Replacement and attach it to the Warranty
Transaction in GWM.
3. As applicable, insert the transmission flush code in the labor operation dependency field.

the failed component being removed and the replacement component being installed.
5. Submit the Warranty Transaction with the appropriate authorization code, if required: As an example: (A / E / P)
Record Retention
