Is Your Truck or Van Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a dependable vehicle that suddenly isn’t. If your Chevrolet, GMC, or Isuzu is suffering from a persistent check engine light, erratic shifting, poor fuel economy, or a no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s a problem that affects your work, your family, and your peace of mind. Instead of guessing with used parts or paying steep dealership prices for programming, get the definitive, plug-and-play solution designed to restore your vehicle’s factory performance.
Common Symptoms & Your Solution
A faulty PCM can cause a cascade of confusing issues. You might be experiencing one or more of the following:
- Illuminated Check Engine Light: Often with communication error codes or internal module failure codes like P0601, P0605, or P0606.
- Poor Engine Performance: Stalling, hesitation, misfires, or a noticeable loss of power.
- Transmission Problems: Harsh or delayed shifting, or getting stuck in one gear.
- Failed Emissions Test: Inability to pass smog inspections due to module-related faults.
- Complete No-Start Condition: The engine cranks but refuses to start due to a lack of fuel or spark command from the PCM.
This Programmed GM PCM 09355699 is the direct answer to these problems. We take a high-quality replacement module and flash it with the latest, most stable GM-certified software calibration for your exact vehicle.

An Expert’s Note: The Work Van That Wouldn’t Quit Quitting
We had a customer, a contractor named Dave, whose ’99 Express 2500 work van was his livelihood. It started stalling intermittently at job sites, becoming unreliable and costing him time and money. His mechanic suspected the PCM but quoted him a fortune for a new one plus programming. Dave ordered a Programmed GM PCM 09355699 from us, provided his VIN, and installed it himself in under 20 minutes in his driveway. The van fired right up, the stalling issue was gone, and he was back on the road the next day. That’s the power of getting the right part, programmed correctly, without the runaround.
Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives fully programmed to the VIN you provide. The only step required after installation is a simple security relearn, which typically involves cycling the ignition key. No special tools are needed.
What information do you need from me?
After you complete your purchase, we will need the 17-digit Vehicle Identification Number (VIN) from your vehicle. This is usually found on your driver’s side dashboard (visible through the windshield) or on the driver’s door jamb sticker.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your original PCM, then this replacement part is the correct solution. It’s crucial to ensure the underlying issue is the module itself and not a separate sensor or wiring problem.
How do I know if this fits my vehicle?
This PCM is compatible with the vehicles listed in the fitment chart and is a direct replacement for part numbers 09355699, 16250279, and 09366810. Matching one of these part numbers from your original module is the best way to confirm compatibility.
Is this a difficult part to install?
For most of the listed GM vehicles, the PCM is located in the engine bay and is held in place by a few bolts and has several large electrical connectors. Installation is straightforward for anyone with basic mechanical skills. Always disconnect the battery before starting.
