Restore Your Vehicle’s Brain, Restore Your Drive
Is your Oldsmobile Alero, Pontiac Grand Am, or other GM vehicle suffering from strange, unpredictable issues? A failing Powertrain Control Module (PCM) can cause a host of frustrating problems, from a persistent check engine light to a car that won’t start at all. This isn’t just an inconvenience; it’s a breakdown in your vehicle’s central nervous system. We offer the definitive solution: a professionally programmed PCM, flashed with the latest GM software and tailored specifically to your vehicle’s VIN. This isn’t a generic, one-size-fits-all part; it’s the precise component you need to get back on the road with confidence and reliability.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways. If you’re experiencing any of the following, your vehicle’s computer is likely the culprit:
- Erratic engine performance, such as stalling, rough idling, or misfires.
- Poor fuel economy and loss of power.
- Failure to pass an emissions test.
- Transmission shifting problems or harsh engagement.
- A persistent Check Engine Light with communication-related Diagnostic Trouble Codes (DTCs), such as P0600-P0606.
- The vehicle cranks but refuses to start.

An Expert’s Note on VIN Programming
As a technician, I’ve seen countless drivers try to save a few dollars with a junkyard module, only to end up with more problems. Without proper VIN programming, a replacement PCM can cause transmission damage, anti-theft system lockouts, or simply fail to start the car. Our process eliminates that risk entirely. By flashing the 1999 Alero PCM 16236757 to your exact VIN before it ships, we ensure all the unique options and calibrations for your car are correctly loaded. It’s the difference between a quick fix and the right fix.
Frequently Asked Questions
What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We cannot ship the module until we have this information, as we use it to program the unit specifically for your car.
Do I need to do any programming myself?
No. This PCM arrives fully programmed and ready for installation. In some cases, a CASE (Crankshaft Angle Sensor Error) relearn procedure may be required after installation, which can be performed by most professional scan tools.
Where can I find my VIN?
Your VIN can be found on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM or a related communication error, this part will resolve the issue. However, it’s crucial to ensure the underlying problem isn’t a separate faulty sensor or wiring issue. We always recommend a proper diagnosis before ordering.
Is this a difficult part to install?
For someone with moderate mechanical experience, replacing a PCM is typically straightforward. It usually involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The exact location varies by model. If you are not comfortable with automotive repair, we recommend professional installation.
