9218oldsmobile02
Number: 92-C-04
Date: November 1991
Section: 7A
Subject:
4T60 REVERSE SERVO APPLY PIN BORE
Models/Years:
CERTAIN 1992 CUTLASS CIERA AND CUTLASS SUPREME MODELS
WITH 4T60 (ME9, 4 SPEED) TRANSAXLE
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1992 Oldsmobile Cutlass Ciera and Cutlass Supreme model vehicles equipped with four speed transaxles (RPO ME9; 4T60). The reverse servo apply pin may bind in the case which could cause reverse band distress (loss or slipping of reverse), reverse band drag in drive range (poor performance/low power), or the vehicle to remain in reverse while the shift indicator shows neutral gear position. If the vehicle remains in reverse while the shift indicator shows neutral, and the driver does not apply the brake, the vehicle may unexpectedly move rearward and cause an accident without prior warning.
To prevent this condition from occurring, dealers are to inspect involved vehicles; then if necessary, test involved vehicles; and, finally, replace transaxles as required. DCS messages # 91-238 and # 91-239, were sent to all Oldsmobile dealers November 11, 1991, to hold all unsold suspect vehicles pending further information. All unsold suspect vehicles MUST be held at dealers and inspected/repaired per the campaign service procedure BEFORE delivery to owners. Completion of this campaign lifts the hold on unsold vehicles in the DCS message.
VEHICLES INVOLVED
Certain 1992 Oldsmobile Cutlass Ciera and Cutlass Supreme model vehicles equipped with 4T60 (option ME9), 4 speed automatic transaxles AND built within Julian date codes 282 though 297 inclusive, AND with machine operation number 50 AND machine unit number 4 (see Figure 2), within the following breakpoints:
Transaxle Beginning Through & Transaxle
Model Model Name Plant Type VIN Including Julian Dates
A Cutlass Ciera Oklahoma City 4T60 N6324248 N6340744 282 - 297
W Cutlass Supreme Doraville 4T60 ND324555 ND333811 282 - 297
NOTE: VIN RANGES ARE DIFFERENT THAN LISTED IN DCS MESSAGE # 91-238.
ABOUT 7% OF INSPECTED VEHICLES MAY REQUIRE A TRANSAXLE REPLACEMENT.
Some of the subject vehicles within the breakpoints listed above were corrected at the assembly plant prior to being shipped to the dealer and will not require inspection by the dealer. Factory corrected transaxles can be identified by a BLACK "X" marked on the barrel of the case as shown in Figure 3. All subject vehicles which are listed on the dealer's campaign printout will require inspection (and as necessary, further action) as outlined in the SERVICE PROCEDURE section of this bulletin. Other suspect vehicles should be checked for campaign involvement by utilizing the Vehicle Information Service System (V.I.S.S.).
DEALER ACTION
Dealers are to perform this campaign on all involved vehicles at no charge to owners, regardless of mileage, age of vehicle, or ownership from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used car inventory, or it is in your dealership for service, you are to ensure the campaign correction has been made before selling or releasing the vehicle.
Dealers are to contact owners of vehicles recently sold from your new or used vehicle inventory and arrange for the campaign correction to be performed.
