Condition
Some customers may comment on one or more of the following conditions:
• Start/Stop inoperative
• MIL illuminated
Some technicians may find DTC P2797 (Auxiliary Transmission Fluid Pump
Performance) set in the Transmission Control Module (TCM).
Cause
This condition may be caused by an internal failure in the auxiliary fluid pump.
Note: Inspect the auxiliary pump harness for a backed out/loose fitting terminal on both
ends of the harness and repair/replace as necessary.
Replace the auxiliary transmission pump. Refer to Automatic Transmission Fluid Pump
Removal and Installation in SI.
Important: To remove the pump assembly, grasp the turbine shaft and remove the
forward clutch and pump assembly as one piece. Keep the clutch assembly inserted in
the pump. This will protect the shaft seals and they will not need to be replaced.
Correction
⇒ Refer to Transmission Fluid Pump Disassemble for instructions on replacing
the auxiliary pump.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
