CAMPAIGN IDENTIFICATION LABEL
Each vehicle corrected in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label". Each label provides a space to include the five (5) digit dealer code of the dealer performing the campaign service. This information may be inserted with a typewriter or ball point pen.
Each "Campaign Identification Label" is to be located on the radiator core support in an area which will be visible when the vehicle is brought in for periodic servicing by the owner.
Apply "Campaign Identification Label" only on a clean dry surface.
ADMINISTRATIVE PROCEDURE
Procedures covering this campaign are outlined in Section V of your dealership's "GMC Truck Claims Processing Manual" #P8719.
Dear GMC Truck Owner:
General Motors has determined that certain 1988 GMC C/K 15-35 Sierra Trucks equipped with 4-speed manual transmission may have been built with a transmission and transmission shift lever which could remain in reverse after being put in that gear.
To correct this condition on your vehicle, please contact your GMC Truck dealer to arrange for a service date to have the transmission cover assembly in your truck replaced. This service will be completed at no charge to you.
Instructions for performing this service have been sent to your GMC Truck dealer. It is estimated that parts will be available to your dealer on September 1, 1987. The labor time necessary to replace the transmission cover assembly in your vehicle will vary from 1-1/2 hours to 2 hours. Please ask your dealer if you wish to know how much additional time will be needed to process your vehicle.
The enclosed 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 let us know by completing the postage paid owner reply card and returning it 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 products.
