CUSTOMER SATISFACTION PROGRAM
SUBJECT:

Auxiliary Transmission Cooler Line

MODELS:

2014 Chevrolet Corvette Convertible

CONDITION
Certain 2014 model year Chevrolet Corvette convertible vehicles have a cooler outlet connector
pipe on the auxiliary transmission cooler that may not be properly sealed to its mating
connection. The improper seal may cause transmission oil to leak or, under certain conditions,
the connector pipe to disconnect from the mating connection. The disconnection of the connector
pipe may result in a loss of vehicle propulsion, and leaking transmission oil could cause smoldering
if it contacts the heated intake exhaust pipes or mufflers.
CORRECTION
Dealers are to replace the auxiliary transmission cooler assembly.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle
History screen in GM Global Warranty Management system. Dealership service personnel should
always check this site to confirm vehicle involvement prior to beginning any required inspections
and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar
vehicles may be involved regardless of description or option content.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle
identification number, customer name, and address information 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. Dealers will not have a report available if they have no involved vehicles
currently assigned.
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 U.S. and Canada
The General Motors Courtesy Transportation program is intended to minimize customer
inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited
Warranties. The availability of courtesy transportation to customers whose vehicles are within the
warranty coverage period and involved in a product program is very important in maintaining
customer satisfaction. Dealers are to ensure that these customers understand that shuttle service
or some other form of courtesy transportation is available and will be provided at no charge.
Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy
Transportation guidelines.

CUSTOMER NOTIFICATION – For U.S. and Canada
General Motors will notify customers of this program by letter (see copy of customer letter included
with this bulletin) and attempt follow-up by telephone.
CUSTOMER NOTIFICATION – For Export
Letters will be sent to known owners of record located within areas covered by the U.S. National
Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify

DEALER PROGRAM RESPONSIBILITY
All unsold new vehicles in dealers' possession and subject to this program must be held and
inspected/repaired per the service procedure of this program bulletin before customers take
possession of these vehicles.
Dealers are to service all vehicles subject to this program at no charge to customers, regardless
of mileage, age of vehicle, or ownership, from this time forward.
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 follow-up 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 in the future, you must take the steps necessary to be sure the program
correction has been made before selling or releasing the vehicle.

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.

Dear General Motors Customer:
We have learned that your 2014 model year Chevrolet Corvette convertible may have a cooler
outlet connector pipe on the auxiliary transmission cooler that may not be properly sealed to its

the connector pipe may result in a loss of vehicle propulsion, and leaking transmission oil could
cause smoldering if it contacts the heated intake exhaust pipes or mufflers.
Your satisfaction with your Corvette is very important to us, so we are announcing a program to
prevent this condition or, if it has occurred, to fix it.
