From the Technician’s Bench: I once had a contractor bring in his ’01 Sierra 3500 dually. The truck was his entire livelihood for hauling heavy equipment, but it was shifting so hard it felt like it was going to tear itself apart. He’d thrown parts at it, but nothing worked. After diagnosing a failing PCM, we installed one of our VIN-programmed units. The change was immediate. The shifts were crisp and smooth, the power was back, and the look of relief on his face said it all. The PCM is the brain of that legendary diesel engine; when it’s working right, the truck feels unstoppable. That’s the confidence we deliver with every module.

Frequently Asked Questions
What do I need to do after I install this PCM?
After installation, you will need to perform a security relearn procedure, which can typically be done without special tools and takes about 30-40 minutes. You may also need to have a qualified technician perform a Crankshaft Variation (CASE) relearn for optimal performance and to clear certain engine codes.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please double-check it for accuracy to ensure a perfect match.
Will this fix my specific problem or check engine light?
This PCM is a direct solution for failures within the module itself, which cause a wide range of symptoms. While it resolves many common issues and check engine codes related to the computer, it is crucial to ensure your vehicle has been properly diagnosed. This part will not fix underlying mechanical or wiring issues.
Is this a brand new part from GM?
This is a quality, tested replacement Powertrain Control Module. Each unit undergoes rigorous inspection and is programmed with official GM software to ensure it meets or exceeds original performance specifications for your vehicle.
Where is the PCM located on my 2001 truck?
On the 2001 Silverado and Sierra HD diesel models, the Electronic Control Module (PCM/ECM) is typically located on the driver’s side of the engine bay, mounted to a bracket underneath the battery tray.
Why is programming to my VIN so important?
Programming the 2001 Silverado 2500 Diesel PCM to your VIN is critical. It ensures the computer has the correct software for your truck’s engine, transmission, emissions equipment, and other factory-installed options. An incorrectly programmed module will not function properly and can cause serious drivability issues.
