Reference: Dealer notification letter # 281T, December, 1989, for 1988-9 AS-Body vehicles with heavy duty trailer tow package and located in Northern U.S.
The initial notification for recall # 281T involved 1988 and 1989 model year AS-Body vehicles equipped with trailer tow and operating in cold climates. The action was taken to eliminate the potential for transmission damage due to oil flow restriction through the oil cooler during cold weather.
The recall population is now being expanded to also include certain additional 4- speed transmission equipped AS, AC and AY-Body vehicles with external transmission oil-to-air coolers operating in frigid climate regions.
Note: Vehicles already equipped with oil cooler bypass valve systems under Technical Service Bulletin # 21-28-89 do not require further service for this condition.
All service requirements for the additional vehicles are the same as for the original Recall # 281T except as noted in the following sections. A copy of the original dealer notification letter of December, 1989 is enclosed for your reference.
