For 1990-2009 cars

# CAMPAIGN: 200-4R MANUAL VALVE LINK SEPARATION

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a product campaign of this type, must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately 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 owner 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 solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the owner letter, owners are being instructed to contact the nearest Cadillac Zone Office if their dealer does not remedy the condition within five days of the agreed service date. If the condition is not remedied within a reasonable time, owners are instructed how to contact the National Highway Traffic Safety Administration.

#### CONDITION

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1987 Cadillac Broughams. These vehicles may have an automatic transmission with a manual valve link which was improperly formed. This condition could lead to the link separating, resulting in a gear selection different from what the driver selects with the shift lever and what appears on the shift indicator. Also, the car could be started when the transmission is in gear. Thus when selecting a gear or starting the vehicle, it is possible for the vehicle to unexpectedly move in an unanticipated direction. Such unexpected movement could result in an accident without prior warning.

#### DEALER ACTION

To prevent the possibility of this condition occurring on vehicles involved, dealers are to replace the transmission manual valve link per the Vehicles Involved and Service Procedure sections of this bulletin.

#### VEHICLES INVOLVED

Certain 1987 Cadillac Broughams within the following VIN range require this campaign:

H9761737 through H9765651

Although approximately 5,000 vehicles fall within this VIN Range, Cadillac records indicate a total of 2,134 vehicles are actually involved. Your Dealer Lists will reflect those determined to be your responsibility.

#### OWNER NOTIFICATION

OWNERS OF VEHICLES AFFECTED BY THIS CAMPAIGN WILL BE NOTIFIED BY LETTER FROM CADILLAC MOTOR DIVISION. A COPY OF THE OWNER LETTER IS ATTACHED.

#### DEALER LIST

A list of vehicles involved is enclosed for your follow-up. The list includes: (A.) Those vehicles originally sold by you, providing the current owner is located in your zone; and, (B.) Those vehicles originally sold outside of your zone whose current owner is located in your area of sales/service responsibility.

This list contains owner names and addresses obtained from state motor vehicle registration records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this list for the follow-up necessary to complete this campaign. If no list is attached, none of the involved vehicles are known to be in your area.

WE SUGGEST YOU USE THE LIST OF "VEHICLES INVOLVED" TO ORDER YOUR INITIAL PARTS REQUIREMENTS AS SOON AS POSSIBLE.

#### DEALER CAMPAIGN RESPONSIBILITY

Dealers are to service all vehicles involved in this campaign, at no charge to owners, regardless of mileage, age of vehicle, or ownership.

Whenever a vehicle subject to this campaign is taken into used car inventory, dealers are to take the steps necessary to be sure the campaign correction has been made before reselling the vehicle.

In addition, dealers are to perform the campaign on all affected vehicles as they are brought in for any kind of service.

Dear Cadillac Owner:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1987 Cadillac Broughams. These vehicies may have an automatic transmission with a manual valve link which was improperly formed. This condition could lead to the link separating, resulting in a gear selection different from what the driver selects with the shift lever and what appears on the shift indicator. Also, the car could be started when the transmission is in gear. Thus when selecting a gear or starting the vehicle, it is possible for the vehicle to unexpectedly move in an unanticipated direction. Such unexpected movement could result in an accident without prior warning.

To prevent the possibility of this condition from occurring on your vehicle, please contact your Cadillac dealer to arrange a service date. Your Cadillac dealer will replace the manual valve link. This service will be completed at no charge to you.

Instructions for making this correction have been sent to your Cadillac dealer. The labor time to perform this correction is approximately forty-five minutes. Please allow additional time for the dealer to process your vehicle.

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.
