North America, Middle East, Israel, S. America, S. Korea, Thailand, Australia, New
Zealand, Egypt and Africa
Some customers may comment on, but not limited to, one or more of the following
conditions:
Note: This is a multi-wire bundled harness and depending on which wire is damaged,
can set a variety of DTCs. Not all of the effects or driver notifications listed have been
experienced. However, the different effects and driver notifications may be caused by one
of the wires in the harness being chafed or cut. Components on different lines in the list
below are in different circuits. Due to the cause of the condition, and the positions of the
wires in the harness, it is unlikely that more than one circuit and/or fuse will be affected by
the condition.

Condition

• MIL illuminated
• Service Transmission message displayed on DIC
• Service Parking Brake/Parking Brake Warning on
• Parking Brake remains on causing no vehicle movement
• Transmission will not shift
• No Reverse
• Stabilitrac message on
• Vibration on rough roads or on acceleration or deceleration (torque related)
Some technicians may find one or more of the following DTCs in history:
• P057D
• P057E
• P0658
• P0700
• P073D
• P07E4
• P16F4
• P175F
• P1778
• P1789
• P2760
• U0073
• U0101
• U0121

Cause

This condition may be caused by one or more of the following conditions.
• Engine wiring harness contacting the transmission mount bracket
• Engine wiring harness contacting a transmission control valve body cover stud.

Correction

Validate and inspect the engine wiring harness at the engine bracket or at the
transmission control valve cover stud, refer to the Service Procedure below.

Important: Service agents must comply with all
International, Federal, State, Provincial, and/or
Local laws applicable to the activities it performs
under this bulletin, including but not limited to
handling, deploying, preparing, classifying,
packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict between
the procedures set forth in this bulletin and the
laws that apply to your dealership, you must follow
those applicable laws.

Note: Possible multiple effects or driver notifications
may be experienced by one of the wires in the engine
harness being chafed or cut in different circuits. Due to
the cause of the condition, and the positions of the
wires in the engine harness, it is unlikely that more than
one circuit and/or fuse will be affected by the condition.
Cars with the 6–speed could have a chafing issue at
the mount location as well, it might not be for the
specific circuit noted. The transmission studs in the 2nd
section are for 9–speed only. The 6–speed has bolts,
not studs.

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.
