Product Details and Specifications

The SC806 sensor from Standard Ignition is engineered to monitor the input shaft speed of automatic transmissions in Buick Encore, Chevrolet Malibu, and Chevrolet Trailblazer models.

Installation Notes and Tips

Installation requires removing the old sensor from the transmission mount and securing the new SC806 sensor using the included bolt.
