On a 1997 Chevrolet S10 with a 4.3L engine and 4WD, the vehicle speed sensor (VSS) buffer module is typically located near the transmission. Specifically, it is mounted on the side of the transmission case, often near the output shaft area. To access it, you may need to raise the vehicle for better visibility and maneuverability. Always refer to a repair manual for precise details and safety precautions.
