Restore Peak Performance to Your GM Vehicle
Is your 2001-2002 Chevrolet Express or GMC Savana van running rough, stalling unexpectedly, or displaying a persistent Check Engine Light? These are classic signs of a failing Powertrain Control Module (PCM), the central computer responsible for managing your vehicle’s engine and transmission. A faulty PCM can lead to a cascade of issues, from poor fuel economy and erratic shifting to a complete no-start condition, leaving you stranded and your business on hold. This replacement PCM, part number 12576160, is the definitive solution to restore your vehicle’s reliability and performance.
From the Diagnostic Bay
We had a 2002 Savana 2500 work van come in that was driving the owner crazy. It would randomly stall at stoplights, but then start right back up. No consistent codes were stored, just a few random communication errors. We checked fuel pressure, sensors, and wiring harnesses for hours. Finally, we monitored the PCM’s internal temperature data and noticed it would spike just before a stall. We swapped in a pre-programmed PCM, and the problem vanished. The original unit had an internal fault that only appeared when it got hot, a common issue with these modules as they age. It’s a reminder that sometimes the ‘brain’ itself is the source of the ghost in the machine.
Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) on your dashboard.
- ✔ Engine stalling, misfiring, or running rough.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
- ✔ Loss of communication with diagnostic scan tools.
Why Choose Our 2001-2002 Express 1500 PCM?
This isn’t just a replacement part; it’s a complete, plug-and-play solution. We take the guesswork and hassle out of the repair process. When you order, you provide us with your vehicle’s Vehicle Identification Number (VIN). Our technicians then use this VIN to flash the module with the latest, most up-to-date OEM software directly from GM. This critical step ensures that the PCM is perfectly matched to your vehicle’s specific configuration, including its engine, transmission, and factory options. This eliminates the need for an expensive trip to the dealership for programming, saving you both time and money.

Frequently Asked Questions
Do I need to do anything after installing this PCM?
In most cases, you will need to perform a security relearn procedure, also known as a CASE relearn or Passlock relearn. This procedure can typically be done without special tools and involves a sequence of key turns. Instructions are widely available online for your specific vehicle, or you can consult a service manual.
Why do you need my VIN?
Your vehicle’s VIN is essential for us to load the correct GM-certified software for your specific engine, transmission, and options. This ensures the module works seamlessly with your vehicle right out of the box, preventing compatibility issues.
Is this a plug-and-play part?
Yes, because we program it to your VIN before shipping, it is a plug-and-play installation. Once you complete the security relearn procedure, your vehicle should start and run correctly. No trip to the dealer for programming is required.
Will this fix my transmission shifting problems?
If your shifting issues are caused by a faulty PCM, then yes, this part will resolve them. The PCM controls transmission shift points and line pressure. However, shifting problems can also be caused by mechanical issues within the transmission, so a proper diagnosis is always recommended.
Where is the PCM located on my 2001 Express Van?
On the 2001-2002 Express and Savana vans, the Electronic Control Module is typically located in the engine compartment, on the driver’s side (LH) towards the rear. Always disconnect the battery before attempting to remove or install any electronic module.
