Restore Peak Performance to Your GM Vehicle
Is your 2001-2002 Pontiac Montana, Chevy Venture, or Oldsmobile Silhouette running poorly? Are you battling a persistent Check Engine Light, experiencing erratic shifting, or dealing with frustrating stalling issues? These are classic signs of a failing Powertrain Control Module (PCM), the central computer that manages your vehicle’s engine and transmission. This replacement PCM, part number 12202600, is the definitive solution to restore your vehicle’s reliability and drivability.
Unlike a generic part from a local store, this module is not a simple off-the-shelf item. We provide a crucial service: programming the module specifically to your vehicle’s unique Vehicle Identification Number (VIN). This step is essential for ensuring perfect communication between the PCM and all other electronic systems in your car. By flashing it with the latest GM software updates, we ensure optimal performance, fuel efficiency, and emissions control, eliminating the guesswork and potential compatibility problems that come with unprogrammed modules.
From the Diagnostic Bay
We had a 2002 Chevy Venture come in that was a real head-scratcher for the owner. It would stall intermittently at stoplights and occasionally refuse to start, but there were no consistent trouble codes, just a generic P0601 (Internal Control Module Memory Check Sum Error) that would pop up now and then. The owner had already replaced the crank sensor and fuel pump with no luck. We hooked up our diagnostic scanner and saw erratic data streams from the PCM. After confirming power and ground to the module were solid, we knew the internal processor was failing. We installed one of our VIN-programmed PCMs, performed the quick security relearn procedure, and the van ran perfectly. The owner was thrilled to have his reliable family vehicle back without wasting any more money on unnecessary parts.
Common Symptoms of a Failing GM PCM
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Stalling, stumbling, or hesitation during acceleration
- ✔ Harsh or erratic automatic transmission shifting
- ✔ A noticeable decrease in fuel economy
- ✔ Engine misfires or rough idling
- ✔ The vehicle fails to start, even with a good battery and starter
- ✔ Communication error codes with a diagnostic scanner

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) is like its fingerprint. It contains specific information about the engine, transmission, emissions systems, and other options. We use the VIN to load the exact GM-certified software and calibrations for your specific vehicle onto the PCM. This ensures flawless compatibility and performance, preventing issues that arise from using a generic, unprogrammed module.
Is any additional programming required after I install it?
In most cases, you will need to perform a simple security relearn procedure after installation. This process, also known as the Passlock or anti-theft relearn, syncs the new PCM with your vehicle’s anti-theft system. It typically takes about 30 minutes and can be done without any special tools. We include instructions to guide you through this straightforward process.
How do I know for sure that my PCM is the problem?
While the symptoms listed are strong indicators, it’s always best to have a proper diagnosis. Common diagnostic trouble codes (DTCs) pointing to a bad PCM include P0600 through P0606. If other potential causes like sensors, wiring, and fuel delivery have been ruled out, the PCM is the most likely culprit, especially if multiple unrelated issues are occurring simultaneously.
Where is this module located on my vehicle?
The location varies slightly by model. On most vans like the Montana, Venture, and Silhouette, you will find the PCM located in the LH (driver’s side) engine compartment, typically inside the air filter housing for protection. On sedans like the Grand Am or Alero, it is often found inside the vehicle, near the LH (driver’s side) center of the dashboard.
Will this part fix my transmission shifting problems?
Yes, in many cases it will. The PCM controls the electronic solenoids inside the transmission that manage shifting. If the PCM is sending faulty signals, it can cause harsh shifts, delayed engagement, or slipping. If the transmission itself is mechanically sound, a new, correctly programmed PCM is often the solution to these electronic shifting issues.
