- ✔ Rough Idling or Stalling: Restores stable engine operation by correcting fuel and air mixture calculations.
- ✔ Poor Fuel Economy: Re-establishes efficient engine parameters to save you money at the pump.
- ✔ Harsh or Incorrect Shifting: Ensures smooth communication between the engine and transmission for seamless gear changes.
- ✔ No-Start Condition: Solves issues where the PCM fails to manage the ignition or fuel systems, leaving you stranded.
- ✔ Complete Plug-and-Play Solution: Arrives pre-programmed to your VIN, making the installation process as simple as possible.
Guided Installation to Restore Peace of Mind
Replacing the PCM is a manageable job for a confident DIYer. Follow these steps for a successful installation.
- Step 1: Safety First. Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to ensure the system is fully discharged.
- Step 2: Locate the Module. On your 2001-2002 Savana 2500, the PCM is typically found in the engine compartment on the driver’s side (LH rear). It’s a silver box with multiple large wiring harness connectors.
- Step 3: Disconnect and Remove. Carefully unclip the wiring harnesses from the old PCM. There are usually locking tabs that need to be released. Once the harnesses are free, unbolt the module from its mounting bracket.
- Step 4: Install the New PCM. Mount your new, pre-programmed PCM securely onto the bracket. Reconnect the wiring harnesses, ensuring they click firmly into place.
- Step 5: Reconnect and Verify. Reconnect the negative battery terminal. The vehicle may require a security relearn procedure to sync the new PCM with your keys. (See our FAQ for more details).
A Mechanic’s Note: The End of the Chase
I once had a customer with a 2002 Express van, a twin to the Savana, that had a ghost of a problem. It would randomly stall at traffic lights, but never threw a consistent code. The owner had already replaced the fuel pump and a few sensors, chasing the issue for weeks. When he brought it to me, we found that the PCM was intermittently failing when it got hot. Installing a pre-programmed module like this one didn’t just fix the van; it ended the frustrating and expensive chase. The relief on his face was immediate—he finally had his reliable workhorse back.

Frequently Asked Questions About Your 2001-2002 Savana 2500 PCM
Do I need to program this module?
No, you do not! That’s the primary benefit of our service. We program the module to the specific Vehicle Identification Number (VIN) you provide before we ship it, so it arrives ready to install.
What is the security relearn procedure?
After installation, some GM vehicles require a simple procedure to sync the new PCM with the anti-theft system. It typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating this cycle three times. This allows the system to recognize the new module. Detailed instructions are readily available online for your specific model.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically find this on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls the transmission’s electronic solenoids and shift points. If your module is failing, it can cause harsh shifting, delayed engagement, or being stuck in one gear. A new, correctly programmed PCM often resolves these issues.
Is this a new or used part?
This is a high-quality, inspected, and tested original equipment part that has been professionally programmed to ensure it meets or exceeds factory performance standards. It’s a reliable and cost-effective alternative to a new dealership part.
