***GM used the same computer for both the automatic or manual transmission equipped vehicles. They also used the same computer for the 4 wheel drive or 2 wheel drive applications. The difference between these applications is in the programming of the computer. With your purchase we program the computer to your 17 digit VIN (vehicle identification number) for an exact match to your vehicle.*Programmed to your specific vehicle with your VIN (vehicle identification number)*Shipped to your door ready to install*1 year replacement guarantee*No core charge –you keep your existing PCM - no extra trips to the post office to return a core.*We ship the same day or the following business day from receipt of your payment and your 17 digit VIN - item is in stock and ready to ship.
*******You can send us your 17 digit VIN at the time of payment in the note to seller section or by sending it to us in an message after you complete your purchase.******GM installed this 12576106 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 GM software that a GM garage would use to reprogram and update your computer. With your purchase we will reprogram the PCM, with the latest software updates available from GM, to your specific vehicle using your VIN (vehicle identification number).******This computer is used and was removed from a running salvaged vehicle. This ECM comes with a 1 year replacement guarantee. We have been in the ECM business for 19+ years. We are also a 19+ year member with Excellent positive response.
******All of our listings are of items that are on are shelves ready to ship. There are no delays.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 an 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 reprogram any OBDII computer purchased from us with your specific VIN number for the latest updated calibrations straight from GM 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 sale you will need to provide us with your VIN number.The core charge alone for the 12576106 PCM from a GM Dealer will cost you more then our total purchase price. There is no core charge with this listing. This is a great opportunity to own a spare ECM.

Many different names have been given to the engine computer since its inception over 30 years ago. Engine computers may be referred to as ECU (engine control unit), ECM (engine control module), PCM (power train control module), Brain Box, ECC (engine control computer), VPCM (vehicle control module), or Fuel Management System.
