Here we have a good used OEM engine computer removed from a 2008 Chevrolet Silverado 2500. This unit is compatible with 2008–2010 trucks equipped with the LMM Duramax diesel engine only. The part is in proper working condition with no damage. Please ensure the part number matches your original unit for compatibility. This module may require programming to work with your specific vehicle. Refer to the photos for the exact condition of the item. We are also parting out the rest of the vehicle, so feel free to reach out if you need anything else.
