Frequently Asked Questions
Do I need to do any programming after installation?
No. This module is shipped fully programmed to your vehicle’s VIN and is ready for installation right out of the box. In some cases, a transmission adaptive pressure relearn procedure may be recommended, but no special tools are required.
How do I provide my VIN?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN, or add it to the ‘notes’ section during checkout. We cannot ship your part until we receive your VIN, as the programming is essential.
Is this the correct part for my truck?
This PCM is a direct fit for the 2001 Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 pickup trucks equipped with the diesel engine. The original part numbers it replaces include 9388505, 97780075, 977800770, and 9355100.
Where is the PCM located on my 2001 truck?
On these specific models, the Electronic Control Module (PCM) is located in the engine bay on the driver’s side (LH side), positioned under the battery tray.
Why is a VIN-programmed module better than a generic one?
A VIN-specific program ensures all the unique options and parameters for your truck are correctly loaded. This includes things like axle ratio, tire size, and emissions equipment, which are critical for proper engine and transmission function. A generic 2001 Silverado 3500 PCM will not operate correctly.
