CAMPAIGN: AUTOMATIC TRANSAXLE 4T60-E. Chevrolet Lumina 1993

Subject: PRODUCT CAMPAIGN 93C19 - AUTOMATIC TRANSAXLE 4T60-E

Model and Year: 1993 CHEVROLET LUMINA

To: All Chevrolet Dealers

General Motors has determined that certain 1993 Chevrolet Lumina model vehicles equipped with 4T60-E automatic transaxles (RPO M13) may contain a distorted channel plate assembly. The suspect channel plate may be bowed, affecting the transaxle "end play". This could result in a variety of symptoms including noise, fluid leaks and eventually loss of forward drive capability.

To prevent the possibility of these conditions occurring, dealers are to replace the transaxle assembly with a new transaxle assembly.

VEHICLES INVOLVED

Involved are certain 1993 Chevrolet Lumina motor vehicles equipped with 4T60-E automatic transaxles (RPO M13) built within the following VIN breakpoints: PLANT YEAR MODEL PLANT CODE FROM THROUGH ---- ----- ----- ----- ---- -------

1993 W-Car Oshawa #1 "9" P9253763 P9258306

1993 W-Car Oshawa #2 "1" P1161408 P1161865

NOTICE: Only certain vehicles within these ranges are affected. Please check your dealer listings or VIS to determine campaign status of vehicle.

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

OWNER NOTIFICATION

Owners will be notified of this campaign on their vehicles by Chevrolet Motor Division (see copy of owner letter included with this bulletin).

DEALER CAMPAIGN RESPONSIBILITY

All unsold new vehicles in dealers' possession and subject to this campaign must be held and inspected/repaired per the service procedure of this campaign bulletin before owners take possession of these vehicles.

Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.

Owners of vehicles recently sold from your new vehicle inventory with no owner information indicated on the dealer listing, are to be contacted by the dealer, and arrangements made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such owners a copy of the owners letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the owner may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

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.
