It has been determined that certain 1989 Chevrolet Cavalier & Corsica/Beretta models produced with 5-speed manual transaxles may have gears with a high carbon content in the tooth surface. 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.

To correct this condition, the involved transaxle assemblies are to be exchanged to prevent the above condition from recurring on the same vehicles as mileage accumulates.

The attached prorate indicates the number of vehicles involved in each Branch.
