Is Your Car Running Rough? Get Back on the Road Fast.
There’s nothing more frustrating than a vehicle you can’t rely on. If your Chevrolet, Pontiac, Buick, or Oldsmobile is suffering from a persistent check engine light, erratic shifting, stalling, or a no-start condition, a faulty Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it affects your car’s performance, fuel economy, and safety. You need a reliable, straightforward solution that gets you back to your life without the hassle and expense of a dealership visit. This is that solution.
Common Symptoms & Your Direct-Fit Solution
A failing PCM can manifest in numerous ways. You might be experiencing one or more of the following issues:
- Illuminated Check Engine Light (CEL) with communication error codes.
- Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0605.
- Poor engine performance, including rough idling, hesitation, or misfires.
- Decreased fuel efficiency.
- Harsh or incorrect automatic transmission shifting.

Expert Insight: The Critical Role of VIN Programming
As a technician with over two decades of experience, I’ve seen countless DIY repairs go wrong because of an unprogrammed module. On these late-90s GM vehicles, the PCM is the central hub that communicates with the engine, transmission, and the anti-theft system (VATS/Passlock). Using a generic, unprogrammed computer will almost always result in a no-start condition because the security systems won’t recognize it. By programming the module to your VIN before shipping, we ensure the security handshake is perfect, all your car’s options are recognized, and the transmission shift points are correct. It’s the difference between a 15-minute fix and a car that needs to be towed to a specialist.

Will this fit models other than the 1999 Lumina?
