Product Details

The Cardone Powertrain Control Module line is built for electronic engine management and, where equipped, transmission control. Part number 77-6106F is intended for select Chevrolet Astro, Blazer, Express 1500, Express 2500, Express 3500, S10, and Silverado 1500, plus GMC Jimmy, Safari, Savana 1500, Savana 2500, Savana 3500, Sierra 1500, and Sonoma models from 2003-2004. This part cross-references OE numbers 12570558 and 12576106 for the same application.

Because this PCM is vehicle-specific, it must be flashed with the correct calibration after installation. Accurate VIN and mileage are required, and on-car programming must be completed after the module is installed to avoid drivability or starting concerns. Search terms such as 2003-2004 Chevrolet Silverado 1500 PCM replacement, 2004 GMC Safari powertrain control module, and Cardone 77-6106F remanufactured PCM apply to this part.

• Some GM vehicles use VATS, Pass Key, or Pass Lock anti-theft systems, and Chrysler models 1996 and newer require VIN programming.
• Ford PATS reset requirements vary by application; check the OE service information for the exact vehicle.
• Refer to the manufacturer service procedure for programming and anti-theft relearn steps before starting the vehicle.
