CAMPAIGN: 5 SPEED MANUAL TRANSAXLE REPLACEMENT

Models: 1989 Cavalier, Sunbird, Grand Am and Cutlass Calais

TO: ALL AFFECTED DEALERS:

General Motors of Canada has determined that certain 1989 Chevrolet Cavalier, Pontiac Sunbird and Grand Am and Oldsmobile Cutlass Calais models were produced with 5-speed manual transaxles which may have gears with a high carbon content in the tooth surfaces. These gears could, as mileage accumulates, damage the softer gears to which they mate. The first notice to a driver would be gear noise resulting from spalling (pitting) of gear surfaces. If the transaxle is left unserviced, internal damage may occur, leading to vibration or the shifter "popping out of gear", and finally to a loss of drive in one or more gears.

Up to ten different gears in each of the involved transaxles may have excess carbide, hence the involved transaxles are to be replaced to prevent the above condition from recurring on the same vehicles as mileage accumulates.

Dear General Motors Customer:

General Motors of Canada has determined that certain 1989 Chevrolet Cavalier, Pontiac Sunbird and Grand Am and Oldsmobile Cutlass Calais models were produced with 5-speed manual transaxles which may have gears with a high carbon content in the tooth surfaces. These gears could, as mileage accumulates, damage the softer gears to which they mate. The first notice to a driver would be gear noise resulting from pitting of gear surfaces. If the transaxle is left unserviced, internal damage may occur, leading to vibration or the shifter "popping out of gear", and finally to a loss of drive in one or more gears.

To prevent this condition from occurring on your vehicle, your GM Dealer will replace the transaxle at no charge to you.

Contact your GM Dealer to arrange a service date. Instructions have been sent to your dealer. Your dealer will need to order the specific type traxsaxle which is designed for your vehicle; hence, you should expect to arrange a service date which will be several working days after your call. The labour time to replace the transaxle is about three (3) hours. Please allow additional time for your Dealer to process your vehicle.

Even if you have already had a gear repair in the transaxle on your vehicle, you need to contact your dealer to have the transaxle replaced; the condition may recur with other gears in the transaxle.

This letter identifies your vehicle. Presentation of this letter to your dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.

Further assistance, if required, may be obtained from our Customer Assistance Centre, toll free, by calling 1-800-263-3777.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
