CAMPAIGN: AUTOMATIC TRANS. SHIFTER ASSEMBLY
Model and Year: 1983-1986 CHEVETTE EQUIPPED WITH AUTOMATIC TRANSMISSION
THIS BULLETIN IS BEING REISSUED TO REVISE THE SERVICE PROCEDURE AND CLAIM INFORMATION SECTIONS OF PRODUCT CAMPAIGN BULLETIN 86C24 ISSUED APRIL, 1988. ALL COPIES OF ORIGINAL BULLETIN 86C24 SHOULD BE DESTROYED.
The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to repair within sixty (60) days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.
If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.
To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owners are being instructed to contact the Chevrolet Customer Assistance center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.
DEFECT INVOLVED
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1983-1986 Chevette model vehicles equipped with an automatic transmission. The automatic transmission shift lever button (detent) mechanism can, over time, wear to the point that the button on the shift lever no longer needs to be depressed to shift from "Drive" to "Reverse." A lever with this condition could be inadvertently bumped or moved from "Drive" to "Reverse" by the driver or a passenger while the vehicle is being driven. A sudden unexpected shifting of the transmission from "Drive" to "Reverse" could cause loss of vehicle control and a vehicle crash could occur.
To prevent this condition from occurring, the automatic transmission shift lever will be replaced with a newly designed lever on all involved vehicles.
VEHICLES INVOLVED
Involved are certain 1983-1986 Chevrolet Chevette model vehicles equipped with an automatic transmission and produced within the following VIN breakpoints:
MODEL/YEAR PLANT FROM THROUGH ---------- ----- ---- ------- 1983 Wilmington DY100001 DY269557 1984 Lakewood EA100001 EA172527 1984 Wilmington EY100005 EY271366 1985 Lakewood FA100002 FA223498 1986 Lakewood GA100002 GA146061
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.

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