Restore Your GM Truck’s Dependability and Power
Is your trusty GMC Savana, Chevy Express, or Silverado plagued by frustrating issues like stalling, a persistent check engine light, or erratic engine behavior? A failing Powertrain Control Module (PCM) is often the hidden culprit behind these problems, acting as a faulty brain for your engine. This direct-replacement PCM is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN with the latest GM software updates. Stop chasing phantom sensor codes and get your workhorse running the way it was meant to.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing engine computer is the likely cause. This pre-programmed module is designed to permanently resolve these issues:
- Unexpected stalling or rough idling
- Difficulty starting the engine
- Poor fuel economy
- Illuminated Check Engine Light (CEL) with various codes
- Failure to pass emissions testing
- Harsh or incorrect shifting patterns
By installing this correctly flashed 1998 Savana 1500 PCM, you’re not just replacing a part; you’re restoring the core logic that controls your engine’s fuel delivery, spark timing, and transmission function, ensuring peak operational efficiency.
Expert Insight: The Power of Proper Programming
For these late-90s GM Vortec engines, the programming inside the PCM is just as critical as the hardware itself. We’ve seen countless vehicles where owners have spent hundreds on sensors and diagnostics, only to find the root issue was outdated or corrupt software in the original computer. By flashing this module with the latest GM calibrations for your specific VIN, we eliminate those software-based gremlins. This process corrects known factory bugs, optimizes fuel tables, and ensures the computer communicates flawlessly with every sensor, restoring the smooth, reliable performance these trucks are famous for.

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as programming is a required step.
Will I need to do anything after installing the PCM?
In most GM vehicles of this era, you will need to perform a security relearn procedure (often called a CASE learn or Passlock relearn). This syncs the new PCM with your vehicle’s anti-theft system and can typically be done without special tools. Instructions are widely available online or in service manuals.
Is this the correct part for my truck or van?
This module replaces part numbers 09366810, 16250279, and 09355699. Please check the extensive fitment list on this page and verify the part number on your original module. If you are unsure, please contact us with your VIN before ordering.
What does ‘flashed with the newest updates’ actually mean?
Think of it like a software update for your phone. Over the years, manufacturers release improved software for their vehicles to fix bugs, improve efficiency, and enhance performance. We ensure your replacement PCM has this latest and most stable software version from GM, which is often better than what your vehicle had from the factory.
My vehicle isn’t a Savana. Will this 1998 Savana 1500 PCM still work?
Yes, absolutely. While we use a specific model in our title for SEO, this PCM fits a wide range of GM trucks, vans, and SUVs from 1998-1999 as detailed in the compatibility list. The critical factor is the part number and the VIN-specific programming we perform.
