Identifying Aftermarket
Non-GM Calibrations
For more details, refer to bulletins 08-06-04-033 (Gasoline Engines) and
08-06-04-006A (Diesel Engines).
General Motors is identifying an increasing number of engine, transmission and
catalytic converter part failures that are the result of non GM – aftermarket engine
and transmission control calibrations being used.
When alteration to the GM released engine or transmission control calibrations
occurs, it subjects powertrain and driveline components (engine, transmission,
transfer case, driveshaft and rear axle) to stresses that were not tested by
General Motors. It is because of these unknown stresses, and the potential to
alter reliability, durability and emissions performance, that GM has adopted a
policy to cancel any remaining warranty coverage to the powertrain and driveline
components, whenever the presence of a non-GM/aftermarket calibration is con-
firmed – even if the non-GM control module calibration is subsequently removed.
