Dear GMC Truck Owner:
General Motors has determined that some 1982 Light and Medium Duty GMC 1500 through 7000 Series Trucks equipped with manual transmissions may have contaminated transmission lubricant. The contaminated lubricant contains an excessive amount of water. Continued usage of this lubricant may result in premature wear of the transmission components and subsequent failure of the transmission.
To correct this condition on your vehicle, it will be necessary to drain and refill the transmission assembly with the proper lubricant. Instructions for the correction have been sent to your GMC Truck Dealer.
Please contact your dealer to arrange a mutually agreed upon service date to have the transmission lubricant replaced. The labor time to perform this correction is approximately thirty (30) minutes. This correction will be performed at no chdrge to you.
The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist him 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.
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.
