Condition

Correction

Certain 2016-2017 model year Chevrolet Camaro vehicles equipped with a 6.2L engine (RPO LT1), rear
differential cooler (RPO KNR), and an 8-speed transmission (RPO M5U), may have a condition in which
the left hand front transmission oil cooler (TOC) line can move out of its design position and come into
contact with either an underbody stud or the transmission mount. This may result in a potential rub
through of the TOC line and transmission fluid may come in contact with a hot surface resulting in hot
surface ignition.
Dealers are to inspect and replace the transmission oil cooler line as required, and cut off the body stud
on the driver side of the vehicle near the transmission support.

Dealer Responsibility
All new, used, GM Certified Used, courtesy transportation vehicles, dealer shuttle vehicles, etc. in dealers' possession
and subject to this program must be held and inspected/repaired per the service procedure of this bulletin before
customers take possession of these vehicles. Involved vehicles must be held and not delivered to customers, dealertraded, released to auction, used for demonstration, or any other purpose.
All GM Certified Used vehicles currently in the dealers’ inventory within the Certified Pre-Owned Inventory System
(CPOIS) will be de-certified and must be held and remedied per the service procedure in this bulletin. Upon submitting
an accepted/paid warranty transaction in the Global Warranty Management (GWM) system, the vehicle can be re-certified
for sale within the CPOIS system, or once again be used in the CTP program.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle,
or ownership, through December 31, 2018. Customers who have recently purchased vehicles sold from your vehicle
inventory, and for which there is no customer information indicated on the involved vehicle listing, are to be contacted by
the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this
bulletin. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Program followup cards should not be used for this purpose, since the customer may not as yet have received the notification letter.
In summary, whenever a vehicle subject to this program enters your vehicle inventory, or is in your facility for service
through December 31, 2018, you must take the steps necessary to be sure the program correction has been made before
selling or releasing the vehicle.
Dealer Reports
For dealers with involved vehicles, a listing with involved vehicles has been prepared and will be provided to U.S. and
Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. The listing may
contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor
vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in
several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to
complete this program.
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, Sections 1.4 and 6.1.10, for
courtesy transportation program details.
Customer Notification
USA & Canada - General Motors will notify customers of this program on their vehicle (see copy of customer letter included
with this bulletin).
Export - Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor
Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached sample letter.

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.

This notice applies to your vehicle, VIN: ________________________________
Dear General Motors Customer:
We have learned that your 2016 or 2017 model year Chevrolet Camaro equipped with a 6.2L engine, rear differential
cooler, and an 8-speed transmission, may have a condition in which the left hand front transmission oil cooler (TOC)
line can move out of its design position and come into contact with either an underbody stud or the transmission mount.
This may result in a potential rub through of the TOC line and transmission fluid may come in contact with a hot surface
resulting in hot surface ignition.
Your satisfaction with your Chevrolet Camaro is very important to us, so we are announcing a program to prevent this
condition or, if it has occurred, to fix it.
What We Will Do: Your GM dealer will inspect and replace the transmission oil cooler line as required, and cut off the
body stud on the driver side of the vehicle near the transmission support. This service will be performed for you at no
charge until December 31, 2018. After that, any applicable warranty will apply.
What You Should Do: Due to limited part availability at this time, and to limit any possible inconvenience, we
recommend that you contact your dealer after February 1, 2017 to schedule an appointment for this repair. By
scheduling an appointment, your dealer can ensure that the necessary parts will be available on your scheduled
appointment date. If a red transmission fluid leak is evident underneath your car, please contact your dealer.
If you have any questions or concerns that your dealer is unable to resolve, please contact the appropriate Customer
Assistance Center at the number listed below.
