Restore Your Vehicle’s Performance and Reliability
Is your 1999 Oldsmobile Alero or other GM vehicle suffering from frustrating issues like a persistent check engine light, erratic shifting, poor fuel economy, or even a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the computer that serves as your vehicle’s brain. This replacement PCM is the definitive, hassle-free solution to restore your car’s proper function and get you back on the road with confidence. We eliminate the guesswork and costly dealership visits by pre-programming this unit specifically for your car using your VIN.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of problems that are often misdiagnosed. If you’re experiencing any of the following, this module is your solution:
- Persistent Check Engine Light (CEL) for codes like P0601, P0602, P0605
- Vehicle fails to start or starts intermittently
- Noticeable decrease in fuel mileage
- Harsh or unpredictable automatic transmission shifting
- Engine stalling, stumbling, or running rough
- Failure to pass emissions testing
This 1999 Alero PCM programmed unit is meticulously flashed with the latest official GM software updates. This ensures it communicates perfectly with your engine, transmission, and all other onboard systems, resolving these issues and often improving overall vehicle operation. It’s a comprehensive fix, not just a temporary patch.
An Expert’s Note on VIN Programming
From over 20 years in the shop, I’ve seen countless drivers waste time and money on used modules from a salvage yard. They seem like a bargain, but without the correct VIN-specific programming, they can cause more problems than they solve—from transmission issues to security system lockouts. Our process eliminates that gamble. We ensure the brain of your car is a perfect match, not a ‘close-enough’ guess. This is the difference between a lasting repair and a recurring headache.

Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to work correctly.
Will I need to do anything after installing this PCM?
In most cases, you will need to perform a simple security relearn procedure, which can typically be done without special tools and takes about 30 minutes. This process allows the new PCM to synchronize with your vehicle’s anti-theft system. Instructions are readily available online for your specific model.
Is this the correct part for my vehicle?
This PCM is compatible with a wide range of GM vehicles. Please review the detailed fitment list on this page and compare the service numbers provided (e.g., 09356741, 16236757) with the number on your original module to ensure a perfect match.
What does “programmed” actually mean?
Programming, or “flashing,” is the process of loading the vehicle-specific software onto the PCM. This software controls everything from fuel injection and spark timing to transmission shift points. By programming it to your VIN, we ensure all these parameters are set exactly as the factory intended for your specific car.
Is this a difficult part to replace?
For most of the vehicles this part fits, the PCM is located in an accessible area, often in the engine bay or under the dashboard. The replacement typically involves disconnecting the battery, unplugging a few electrical connectors, and unbolting the old module. It is a manageable job for a confident DIYer with basic hand tools.
