Is a vss buffer or drac used in a 1996 Chevy 3500 4x4 5.7 gas engine truck?

A 1996 Chevy 3500 4x4 with a 5.7 gas engine typically does not use a VSS (Vehicle Speed Sensor) buffer or a DRAC (Digital Ratio Adapter Converter). Instead, it employs a VSS that directly feeds the speed signal to the engine control module (ECM) and the speedometer. The DRAC was more commonly used in older models or specific configurations, but it is not standard for this particular truck.
