SERVICE UPDATE
SUBJECT:

Service Update for Inventory Vehicles Only
Transmission Snap Ring Misalignment
Expires September 30, 2014

MODELS:

2013 Buick Regal, LaCrosse
2013 Chevrolet Malibu
Equipped with 6T40 Automatic Transmission (MHH)

Vehicles involved in this service update were placed on stop delivery August 29, 2013.
Completion of the service procedure contained in this bulletin will release the vehicle
from stop delivery and allow a dealer to deliver the vehicle to a customer.
An analysis of transmission build data revealed that there could be a durability issue with
the transmissions originally installed in these vehicles. To ensure the highest quality and
best ownership experience for our customers, these transmissions need to be replaced
prior to vehicle delivery. In the interest of full disclosure, dealer must inform the
customer of the transmission repair before the customer purchases the vehicle. Some
states and provinces also have laws or regulations requiring disclosure.
A written
acknowledgement of this pre-delivery repair from the customer is strongly
recommended.
PURPOSE
This bulletin provides a service procedure to replace the transmission assembly on certain 2013
model year Buick Regal, LaCrosse and Chevrolet Malibu equipped with 6T40 automatic
transmission (MHH). The transmissions in these vehicles may have been assembled with an
improperly manufactured snap ring. A burr on the snap ring can cause it to stick to the
aluminum housing causing the snap ring to compress and come out of the retaining groove. If
this occurs, the Check Engine Light illuminates and the transmission enters default mode
(Second Gear - 65 mph or 104 km/h maximum and Reverse Gear operation only). Customer
complaints may include no shift, erratic shifts, growls and slipping, hesitation and jerks.

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.
