Sensor mounts between the transmission and speedometer cable, and supplies the ECM with the needed vehicle speed signal. Can be used with just about any Chevy transmission. 7/8-18 thread, .104 square drive. Installation instructions included.

Note - this sensor will not work on applications that use a VSS buffer box. If you will be using a VSS buffer box, contact us so we can assist you in identifying what VSS you need.
