BULLETIN COVERS:
New calibration update kit packages that contain calibration update items required when the overhaul and 3rd clutch plate assembly packages are no
longer available for early 1989 HYDRA-MATIC 4T60 models built before March 17, 1989 (Julian Date 076) (this includes early 1990 Cutlass Supreme

new style 3rd clutch plates must be used with the calibration update kit packages listed under "Service Parts Information".
