CAMPAIGN: TRANSAXLE HARSH SHIFTS OR SLOW RESPONSE. Oldsmobile Cutlass Supreme 1995

SUBJECT: TRANSAXLE HARSH SHIFTS or SLOW RESPONSE

YEAR: 1995

MODEL: CUTLASS SUPREME W/3.4L DOHC (VIN X) ENGINE

DEFECT INVOLVED

General Motors has decided that certain 1995 Oldsmobile Cutlass Supreme model vehicles equipped with a 3.4L DOHC (RPO LQ1) engine may have been built with a partially or fully blocked transaxle modulator port on the intake manifold plenum vacuum distribution block. This can result in harsh transaxle shifts or slow response of the vacuum modulator during certain driving conditions which could cause reduced customer satisfaction or durability. Replacement of the vacuum distribution block will allow the transaxle to have sufficient line pressure response to control bands and clutches during vehicle operation.

To prevent this condition from occurring, retailers are to replace the suspect intake manifold vacuum distribution block with a new part on all affected vehicles.

VEHICLES INVOLVED

Involved are all of the following sixteen (16) 1995 Oldsmobile Cutlass Supreme model vehicles equipped with the 3.4L DOHC VIN X (RPO LQ1) engine:
