For 1990-2009 cars

# CAMPAIGN: TRANSAXLE SHIFT CABLE DISENGAGEMENT

#### Subject: TRANSAXLE SHIFT CONTROL CABLE DISENGAGEMENT

#### Models/Years: 1991 TOURING SEDAN

#### CONDITION

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1991 Oldsmobile Ninety Eight Touring Sedans. The transaxle shift control cable may disengage from the shift control cable bracket (at the transaxle) resulting in loss of gear indicator reference and shift selector operation. The gear position indicated by the selector may differ from the actual gear position of the transaxle with the transaxle remaining in the position last selected prior to cable disengagement. If this occurs, a number of possible conditions can exist. Unless the transaxle is actually in the park or neutral position, the engine can not be started.

If the driver places the gear shift selector in the park position without setting the parking brake, the transaxle may not actually be in the park position and the vehicle may move if it is on an inclined surface. Also, if the driver places the gear shift selector in a drive or the reverse position without turning off the engine, the transaxle may not be in the position indicated and the vehicle may move in the opposite direction. In either case, unexpected vehicle movement could result in an accident without prior warning.

To correct this condition, dealers are to install two transaxle shift control cable retaining clips on each suspect vehicle as per the VEHICLES INVOLVED and SERVICE PROCEDURE sections of this bulletin.

#### DEALER ACTION

Dealers are to perform this campaign on all involved vehicles at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time forward.

Whenever a vehicle subject to this campaign is taken into your new or used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.

Dealers are to contact owners of vehicles recently sold from your new or used vehicle inventory and arrange for the campaign correction to be performed.

#### SERVICE PROCEDURE

1. Set parking brake and open hood.

2. Make sure the transaxle shift control cable is properly seated in the shift control cable bracket (see illustration, View A). Insert two retaining clips between the shift cable body and the cable retaining tabs (as per View A). This will force the tabs outward so that the cable is firmly locked to the bracket.

3. Install a Campaign Identification Label.

4. Close hood and release parking brake.

#### CAMPAIGN IDENTIFICATION LABEL

Each label provides space to print the campaign number, and the five (5) digit dealer code of the dealer performing the campaign. Insert this information with a typewriter or ballpoint pen. When installing label, clean and dry the surface of the radiator support tie bar and apply the campaign label where it is readily visible.

#### PARTS INFORMATION

Two retaining clips for each vehicle involved will be shipped with the VIN list to involved dealers by Oldsmobile on a no charge basis.

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.
