To: All Dodge and Chrysler-Plymouth Dealers

Subject: Customer Satisfaction Notification # 281T Transmission Oil Cooler Bypass Valve

Models: 1988 and 1989 S-Body Models Equipped With Heavy Duty Trailer Tow Package -- Plymouth Voyager and Grand Voyager, Dodge Caravan, Grand Caravan, Caravan C/V and Grand Caravan C/V

The listed model vehicles equipped with the trailer tow package may experience restricted transmission fluid flow through the oil cooler at low temperature (-15 degrees F and below). This may result in lack of lubrication to the transmission and possible transmission failure.

To ensure adequate lubrication, a transmission oil cooler bypass valve system must be installed.

Important: Some of the involved vehicles may still be in dealer inventory. Be sure to complete the service on these vehicles before delivery to customers.

Because of the cold weather nature of the condition, only those vehicles invoiced to dealers in the Northern U.S. are included in this notification and service action. The following Zones are included:

Boston, Chicago, Denver, Detroit, Kansas City, Milwaukee, Minneapolis, Pittsburgh and Syracuse; also the State of Alaska.

Parts distribution and Vehicle Lists will be limited to these dealers. However, vehicles in other areas are eligible for the repair as needed to meet cold weather operation requirements upon owner request.

Details of this service action are explained in the following sections. As an additional service aid, a videotape demonstrating the service procedure is included in the December, 1989 Master Tech program.
