Recall Bulletin

EQUIPMENT NONCOMPLIANCE RECALL
SUBJECT:

Transmission Control Module

MODELS:

2014 Chevrolet Silverado HD
2014 GMC Sierra HD
Equipped with Allison A1000 Transmission (RPO MW7)

This bulletin has been revised to include a copy of the customer letter. Please discard all
copies of bulletin 13442.
All involved vehicles that are in dealer inventory must be held and not delivered to customers,
dealer traded, or used for demonstration purposes until the repair contained in this bulletin has
been performed on the vehicle.
CONDITION
General Motors has decided that a motor vehicle equipment defect has caused 2014 model
year Chevrolet Silverado HD and GMC Sierra HD vehicles equipped with an Allison A1000
transmission (RPO MW7) to fail to conform to Federal Motor Vehicle Safety Standard 102.
These vehicles were reprogrammed with a 2015 model year software and calibration which
was inadvertently released by GM for service. If the driver moves the transmission shift lever
to the “1” position, the PRNDM display will not indicate the position selected. If the driver is
not aware of the position of the shift lever and attempts to accelerate only in first gear, it could
increase the possibility of a crash without prior warning. Our records indicate that 28 vehicles
were reprogrammed by dealers.
CORRECTION
Dealers are to reprogram the transmission control module with the correct software and
calibration.
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.

Bulletin No.: 13442A

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 US and Canadian dealers through the GM GlobalConnect Recall
Reports. 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 recall 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 recall.
PART INFORMATION
No parts are required.
SERVICE PROCEDURE


DO NOT program a control module unless directed to by a service procedure or a
service bulletin. If the control module is not properly configured with the correct
calibration software, the control module will not control all of the vehicle features
properly.



Do NOT attempt to order the calibration number from GM Customer Care and
Aftersales. The calibration numbers required for this service procedure are
programmed into control modules via a Multiple Diagnostic Interface (MDI) with the
calibration update. Use TIS2WEB on or after 12/12/13 to obtain the calibration. If you
cannot access the calibration, call the Techline Customer Support Center and it will be
provided.



Ensure the programming tool is equipped with the latest software and is securely
connected to the data link connector. If there is an interruption during programming,
programming failure or control module damage may occur.



Stable battery voltage is critical during programming. Any fluctuation, spiking, over
voltage or loss of voltage will interrupt programming. When required install the EL49642 SPS Programming Support Tool to maintain system voltage. If not available,
connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage
supply. DO NOT connect a battery charger.



Turn OFF or disable systems that may put a load on the vehicles battery such as;
interior lights, exterior lights (including daytime running lights), HVAC, radio, etc.



During the programming procedure, follow the SPS prompts for the correct ignition
switch position.



Clear DTCs after programming is complete. Clearing powertrain DTCs will set the
Inspection/Maintenance (I/M) system status indicators to NO.

To program an existing transmission control module (TCM), perform the following procedure:
1. Install EL-49642 SPS programming support tool.
2. Connect a scan tool to the vehicle and access SPS. Refer to Service Programming System
(SPS) in SI.
3. Ensure the ignition switch is in the RUN position.

(SPS) documentation in SI for programming instructions.
4.1 Access the Service Programming System (SPS) and follow the on-screen instructions.
4.2 On the SPS Supported Controllers screen, select TCM Transmission Control Module -Programming and follow the on-screen instructions.
5. At the end of programming, choose the “Clear All DTCs” function on the SPS screen.
6. With a scan tool, clear All DTCs.
COURTESY TRANSPORTATION – For US 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 US and Canada
General Motors will notify customers of this recall on their vehicle (see copy of customer letter
included with this bulletin).
DEALER RECALL RESPONSIBILITY – For US and Export (US States, Territories, and
Possessions)
It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used
item of motor vehicle equipment (including a tire) covered by this notification under a sale or
lease until the defect or noncompliance is remedied.
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject
to a recall of this type must be adequately repaired within a reasonable time after the customer
has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima
facie evidence of failure to repair within a reasonable time. If the condition is not adequately
repaired within a reasonable time, the customer may be entitled to an identical or reasonably
equivalent vehicle at no charge or to a refund of the purchase price less a reasonable
allowance for depreciation. To avoid having to provide these burdensome remedies, every
effort must be made to promptly schedule an appointment with each customer and to repair
their vehicle as soon as possible. In the recall notification letters, customers are told how to
contact the US National Highway Traffic Safety Administration if the recall is not completed
within a reasonable time.

Bulletin No.: 13442A

This bulletin is notice to you that the new motor vehicles included in this recall may not
comply with the standard identified above. Under Title 49, Section 30112 of the United
States Code, it is illegal for a dealer to sell a new motor vehicle which the dealer knows
does not comply with an applicable Federal Motor Vehicle Safety Standard. As a
consequence, if you sell any of these motor vehicles without first performing the recall
correction, your facility may be subject to a civil penalty for each such sale.
DEALER RECALL RESPONSIBILITY - All
All unsold new vehicles in dealer's possession and subject to this recall must be held and
inspected/repaired per the service procedure of this recall bulletin before customers take
possession of these vehicles.
Dealers are to service all vehicles subject to this recall 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 dealer 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. Recall 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 recall enters your vehicle inventory, or is in
your facility for service in the future, you must take the steps necessary to be sure the recall
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.

January 2014

Dear General Motors Customer:
This notice is sent to you in accordance with the requirements of the National Traffic and
Motor Vehicle Safety Act.
General Motors has decided that a motor vehicle equipment defect has caused 2014 model
year Chevrolet Silverado HD and GMC Sierra HD vehicles equipped with an Allison A1000
transmission to fail to conform to Federal Motor Vehicle Safety Standard 102. As a result, GM
is conducting a recall. We apologize for this inconvenience. However, we are concerned
about your safety and continued satisfaction with our products.

IMPORTANT




Your vehicle is involved in recall 13442.
Schedule an appointment with your GM dealer.
This service will be performed for you at no charge.

Why is your
vehicle being
recalled?

These vehicles were reprogrammed with a 2015 model year
software and calibration which was inadvertently released by GM for
service. If the driver moves the transmission shift lever to the “1”
position, the PRNDM display will not indicate the position selected.
If the driver is not aware of the position of the shift lever and
attempts to accelerate only in first gear, it could increase the
possibility of a crash without prior warning.

What will we
do?

Your GM dealer will reprogram your vehicle’s transmission control
module with the correct software and calibration. This service will
be performed for you at no charge. Because of service scheduling
requirements, it is likely that your dealer will need your vehicle
longer than the actual service correction time of approximately 30
minutes.
If your vehicle is within the New Vehicle Limited Warranty, your
dealer may provide you with shuttle service or some other form of
courtesy transportation while your vehicle is at the dealership for
this repair. Please refer to your Owner Manual and your dealer for
details on courtesy transportation.

What should
you do?

You should contact your GM dealer to arrange a service
appointment as soon as possible.
