Is Your Truck or Van Running Rough? Get It Back on the Job.
A failing Powertrain Control Module (PCM) is more than an inconvenience—it’s downtime for your work van, family SUV, or trusty pickup. If you’re dealing with a persistent check engine light, erratic shifting, stalling, or a no-start condition, the vehicle’s computer is likely the culprit. This isn’t just a part; it’s the solution to restore the reliable performance you depend on. We provide a professionally programmed Programmed 1999-2002 Express 1500 PCM that arrives ready to install, getting you back on the road without a costly trip to the dealership.
Common Symptoms of a Failing PCM & Your Solution
A faulty PCM can cause a wide range of frustrating issues. You might be experiencing:
- Check Engine Light (CEL): Often with communication error codes like P0601, P0602, or P0606.
- Poor Performance: Reduced power, terrible fuel economy, and hesitation during acceleration.
- Transmission Problems: Harsh or incorrect shifting, or getting stuck in one gear.
- Engine Stalling: The engine may stall intermittently or fail to start at all.
- Failed Emissions Test: Inability to communicate with the OBD-II port or incorrect sensor readings.
This module is the definitive fix for these problems. By providing us with your Vehicle Identification Number (VIN) during checkout, we flash the unit with the latest official GM software specific to your vehicle’s configuration. This ensures all systems—from the engine and transmission to the anti-theft system—function exactly as the factory intended.

An Expert’s Note on VIN Programming: Why is programming so critical for these vehicles? This isn’t just about making the engine run; the PCM is the central hub that communicates with nearly every other module. Without the correct VIN-specific software, your transmission may shift incorrectly, your ABS might not function properly, and the vehicle’s anti-theft system (VATS/Passlock) will prevent the engine from starting. Our service ensures all these components are perfectly synchronized from the moment you turn the key, avoiding the complex and expensive troubleshooting that comes with a generic, non-programmed unit.
Don’t let a faulty computer keep your vehicle sidelined. This Programmed 1999-2002 Express 1500 PCM is your direct path to a reliable repair. By matching the software to your VIN, we ensure a seamless integration that restores the performance and dependability you need to get the job done.
