Parts Information

In most instances, parts will not be required to complete this campaign. However, if transmission fluid shows signs of excessive heat, a transmission will be required and should be ordered from General Motors Service Parts Operations (GMSPO). These parts should be ordered on a "C.I.O." order with no special instruction code, but on an advise code two (2).

NOTICE:
The correct transmission assembly is based on the engine option and axle ratio combination of each vehicle. Refer to the GMSPO parts selection catalog for the correct transmission assembly for each vehicle.
