Adjustment

Certain 2016 Chevrolet Silverado, GMC Sierra/Yukon and Cadillac Escalade vehicles with a 6.2L
engine may have a condition that affects the electrical connection to the transmission oil temperature
sensor. If this condition occurs, rough transmission shifts or hesitation during acceleration may occur.
Additionally, the Malfunction Indicator Light (Check Engine Light) would illuminate and a diagnostic
trouble code related to the temperature sensor would set.
This special coverage covers the condition described above for a period of 10 years or 120,000 miles
(193,000 km), whichever occurs first, from the date the vehicle was originally placed in service,
regardless of ownership.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after July
29, 2020, are covered by this special coverage and must be submitted using the labor operation codes
provided with this bulletin. Claims with repair orders prior to July 29, 2020, must be submitted to the
Service Contract provider.

and does not confer any third party beneficiary, subrogation or contribution rights, or any other rights

Service Procedure
1.

A customer’s vehicle may present with MIL illumination, rough shifting, and/or hesitation during acceleration. DTCs
present may include P0711, P0712, P0713. Following SI diagnostics for these issues may lead to a diagnosis of a
failed transmission control wiring harness contained inside the transmission oil pan, or a failure of the transmission
fluid temperature sensor included in that harness.
•

If following the diagnostics in SI does NOT lead to a diagnosis of an issue with the transmission control
wiring harness or transmission fluid temperature sensor, no further action is required. Claim up to one
hour of diagnostic time and inform the customer that any further diagnosis or repair will not be covered
by this special coverage.

•

If following the diagnostics in SI DOES lead to a diagnosis of an issue with the transmission control
wiring harness, or transmission fluid temperature sensor, replace the transmission control wiring
harness. Refer to Transmission Control Wiring Harness Replacement in SI.

Courtesy Transportation – For USA & Canada
Courtesy transportation is available for Customers whose vehicles are involved in a product program and still within the
warranty coverage period. See General Motors Service Policies and Procedures Manual for courtesy transportation
program details.
Customer Notification
General Motors will notify Customers of this special coverage on their vehicle (see copy of typical Customer letter included
with this bulletin).
Customer Reimbursement
Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to
be submitted to the dealer prior to or by August 31, 2021. See General Motors Service Policies and Procedures Manual,
Product Field Action Customer Reimbursement Procedure (USA & Canada) or local Policies and Procedures, for details.

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 tools, equipment, 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 dealer for information on whether your
vehicle may benefit from the information.
