Get Your Trusted GM Truck Back on the Road
Is your reliable Chevy, GMC, or Cadillac acting up? A faulty Powertrain Control Module (PCM) can be the hidden cause of frustrating issues that leave you stranded. If you’re dealing with a no-start condition, poor engine performance, or a persistent check engine light, you’ve found the solution. This genuine OEM Powertrain Control Module is the brain of your vehicle, and we provide it expertly programmed to your specific VIN, ensuring you can get your workhorse back in service with minimal downtime.
Common Symptoms & Your Solution
A failing engine computer can mimic a wide range of other mechanical problems. Before you spend hundreds on unnecessary parts, see if your vehicle is exhibiting these classic signs of a bad PCM:
- Engine cranks but refuses to start
- Random stalling or rough, inconsistent idling
- Poor fuel economy and loss of power
- Harsh or erratic automatic transmission shifting
- Check Engine Light is on with communication-related trouble codes (U-codes)
- Various electronic systems acting erratically
This pre-programmed GM 9355699 PCM is the definitive fix for these problems. We take a quality, inspected OEM unit and flash it with the latest official GM software calibrated specifically to your vehicle using the VIN you provide. It arrives ready for a straightforward installation, saving you a costly trip to the dealership for programming.

Expert Insight: The Critical Role of VIN Programming
On these late-90s GM vehicles, the PCM is deeply integrated with the vehicle’s anti-theft system (often Passlock I or II). Simply swapping a computer from another truck won’t workโthe vehicle will not start. That’s why our VIN programming service is essential. We don’t just load generic software; we match the module’s calibration files and security information to your exact vehicle. This ensures the new PCM is accepted by the Body Control Module and other systems, allowing for a successful and permanent repair. This attention to detail is what separates a quick fix from a reliable, long-term solution for your GM 9355699 PCM.
Frequently Asked Questions
What information do you need from me?
After you place your order, we will need the 17-digit Vehicle Identification Number (VIN) from your truck, van, or SUV. This is typically found on your driver’s side dashboard (visible through the windshield) or on the door jamb sticker.
Will I need to do anything after installing this PCM?
In most cases, you will need to perform a simple security relearn procedure. This can be done without any special tools and typically takes about 30 minutes. This process allows your vehicle’s anti-theft system to synchronize with the replacement GM 9355699 PCM. We can provide instructions for this procedure.
Is this a new part?
No, this is a high-quality, used OEM part that has been sourced from a salvaged vehicle. Each unit is carefully inspected and tested to ensure it is fully functional before being programmed and shipped to you.
How can I be sure this will fit my vehicle?
The best way to ensure compatibility is to match the part number from your original computer to one of the numbers listed in our description (e.g., 9355699, 16266645). Please review the detailed fitment list on this page carefully. If you are unsure, please contact us with your VIN before ordering.
What if my check engine light comes back on?
While this PCM will resolve issues related to a faulty computer, it will not fix other mechanical or electrical problems. If a check engine light returns, we recommend having the new codes scanned to diagnose any other potential issues with your vehicle.
