engine and transmission computers

listed below are GM factory surplus, OEM parts - new, never used or remanufactured. We carry ECU/ECM/PCM and TCM modules that fit a variety of GM made vehicles, such as the Chevrolet Silverado, GMC Sierra, Pontiac GTO, Cadillac CTS, and many more. Any EMC may work for a number of vehicles that match certain specifications, such as engine size and fuel type.

While it is sometimes possible to repair a faulty ECM with the proper skills and tools, an ECM can be damaged beyond repair. All of the ECM/PCM/ECU computers available on our website are new OEM GM factory surplus, and not remanufactured (repaired). There is no core charge when you purchase an EMC from SMC Performance and Auto Parts.

Please verify correct module fitment with your GM dealer using your vehicle identification number (VIN).
