Product Details

Cardone’s Transfer Case Control Module line focuses on remanufactured electronic modules that are tested before release and rebuilt with attention to connection integrity. For vehicles such as the Chevrolet Trailblazer, GMC Envoy, and Saab 9-7x, this module is intended to restore transfer case communication and control when the original unit has failed or become inconsistent.
