CAMPAIGN: KINKED TRANS. AUX. OIL COOLER INLET LINE
CUSTOMER SATISFACTION CAMPAIGN
SUBJECT: 96-C-33(A)- KINKED TRANSMISSION AUXILIARY OIL COOLER INLET LINE ---------------------------------------------------------------
MODELS: 1996 K- PICKUPS & C/K SUBURBANS WITH DIESEL ENGINE (L56/L65) AND 4L80-E AUTOMATIC TRANSMISSION (MTI) BUILT AT OSHAWA & JANESVILLE ASSEMBLY PLANTS ---------------------------------------------------
THIS CAMPAIGN UPDATES AND REPLACES GMC CAMPAIGN NUMBER 96-C-33, ISSUED JUNE 1996. REVISIONS HAVE BEEN MADE TO THE CAMPAIGN NUMBER IN THE HEADER ON PAGE 6 & 7 AND THE BEGINNING PARAGRAPH IN THE CUSTOMER LETTER.
ALL COPIES OF 96-C-33 SHOULD BE DESTROYED.
General Motors has decided that certain 1996 K- Pickups and C/K Suburbans with diesel engine (L56/L65) and 4L80-E automatic transmission (MT1) built at Oshawa and Janesville Assembly plants, may have a condition in which the automatic-transmission auxiliary oil-cooler inlet hose is kinked. Restricted transmission fluid flow can result from this kinked hose, which can cause lack of lubrication to the transmission gear components. This can result in premature wearing of load carrying members, which can lead to noises, slipping, and/or loss of gear ranges, and eventually complete loss of transmission function. Further, since the kinked hose is not readily noticeable to the dealer, transmission replacement without correcting the kinked hose condition can result in repeat transmission failures.
To correct this condition, dealers are to inspect for a kinked oil-cooler inlet hose. If it is kinked, a new hose will be installed, and if the vehicle has customer usage, the transmission fluid will be changed.
VEHICLES INVOLVED
Involved are CERTAIN 1996 K Pickups and C/K Suburbans with L56/L65 6.5L diesel engines and 4LBO-E automatic transmissions built within the following VIN breakpoints:

Dear GMC Customer:
As a valued customer, your complete satisfaction with your 1996 GMC Sierra or Suburban is our goal. In keeping with this goal, we want to let you know that we have discovered a condition that could affect your vehicle and we want to take care of it at no charge to you.
CERTAIN 1996 K- Pickups and CIK Suburbans with diesel engine (L56/L65) and 4L80-E automatic transmission (MT1) built at Oshawa and Janesville Assembly plants, may have a condition in which the automatic- transmission auxiliary oil-cooler inlet hose is kinked. Restricted transmission fluid flow can result from this kinked hose, which can cause lack of lubrication to the transmission gear components. This can result in premature wearing of load carrying members, which can lead to noises, slipping, and/or loss of gear ranges, and eventually complete loss of transmission function.
C/K Trucks equipped with 6.5L diesel engines built at Oshawa Truck Assembly or at Janesville Assembly, may have an automatic-transmission auxiliary oil-cooler inlet hose that is kinked. Restricted transmission fluid flow can result from this kinked hose, which can cause lack of lubrication to the transmission gear components. This can result in premature wearing of load carrying members, which can lead to noises, slipping, and/or loss of gear ranges, and eventually complete loss of transmission function.
To be sure that your vehicle is to specifications, we will inspect for a kinked oil-cooler inlet hose. If it is kinked, a new hose will be installed, and the transmission fluid will be changed.
Instructions for performing this service have been sent to your GMC dealer, and parts are available. Please contact your GMC dealer to arrange a service date as soon as possible. This procedure will take about 2 hours to complete, but you should ask how much additional time your dealer will need to schedule and process your vehicle.
The enclosed postage paid owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please furnish us the complete name and address of the person you sold or traded your vehicle to and return the card to us.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our product.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 equipment, tools, 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
