******GM installed this 12605843 PCM in all of the above applications.  This was possible because each of these models received their specific programming from the factory.  In other words, you can't simply swap a used PCM from one vehicle to the next.  We are a licensed user of the same software that your local dealer would use to program and update your computer.  With your purchase, we will program the PCM to your VIN (vehicle identification number) with the latest software updates available from GM.

******This PCM is used and was removed from a running salvaged vehicle.  This PCM comes with a 1-year replacement guarantee.  We have been in the PCM business for 17+ years.  We are also a 17+ year eBay member with an Excellent positive feedback score.

Other info:

Why buy your spare PCM from us?  You will be purchasing a high quality used PCM.  You get free Flash programming with every OBDII GM computer purchased. OBDII type computers have the “chip” embedded into the PCM and it is not removable.  The calibration file per the application is “Flashed,” or reprogrammed using a software package and a pass through device.  The “chip” is no longer removed for programming.  Proper programming is essential when replacing a PCM whether it is a used PCM or a remanufactured PCM.  A used GM computer will have the software installed that pertains to the original vehicle that it was removed from.  In some cases, GM OBDII type computers will interchange with many different vehicles including those with different engine and transmission configurations.  However, unless the computer is programmed with the correct software it won’t function properly upon installation.  We will flash program the computer purchased from us with your specific VIN number for the latest updated calibrations available for a stock calibration.  This is important to ensure specific vehicle programming and to guarantee flawless performance in your vehicle. At the end of the auction you will need to provide us with your VIN (Vehicle Identification Number).
