BULLETIN COVERS:
Some 1989 through 1991 6000 or Grand Prix models equipped with a 2.8L (VIN W) or 3.1L (VIN T) engine and a HYDRA-MATIC 4T60 transaxle
may exhibit a 3-2 light throttle tip-in flare/slip-bump condition at 18-24 MPH. A new 3-2 line control system and spacer plate are now available that will
better control the transaxle operation. These conditions can be corrected by replacing the components listed under "Service Procedure".
