Is Your GM Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a trusted vehicle that suddenly won’t perform. If your early 2000s Impala, Grand Am, Monte Carlo, or other GM vehicle 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 a part; it’s the brain of your engine. We offer the definitive, hassle-free solution: a reliable, VIN-specific Programmed 09378702 PCM that gets your car running smoothly again.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of confusing issues that might seem unrelated. Before you spend hundreds on sensors or transmission work you don’t need, see if these symptoms sound familiar:
- Check Engine Light: Specifically for internal module fault codes like P0601, P0602, P0603, P0604, P0605, or P0606.
- No-Start or Stalling: The engine cranks but won’t fire up, or it stalls intermittently while driving.
- Harsh or Erratic Shifting: Your automatic transmission may shift hard, slip between gears, or get stuck in one gear (limp mode).
- Poor Performance & Fuel Economy: A noticeable drop in power, hesitation during acceleration, and more frequent trips to the gas station.
- Communication Errors: Your diagnostic scan tool cannot communicate with the PCM.
This Programmed 09378702 PCM is the direct solution to these problems. We take the guesswork out of the repair by pre-flashing the module with the latest GM software updates, tailored specifically to your vehicle’s Vehicle Identification Number (VIN). It arrives ready to install, saving you a costly trip to the dealership for programming.

Expert Insight: The Ghost in the Machine
“We once had a customer with a 2001 Monte Carlo who was convinced his transmission was failing. It was shifting hard and randomly dropping into neutral. He had already replaced the vehicle speed sensor and the shift solenoids with no luck. The real culprit? A failing PCM was sending erratic signals to the transmission. Once he installed our Programmed 09378702 PCM, all the ‘transmission’ problems vanished instantly. A failing computer can mimic many other mechanical issues, so always verify the PCM’s health before replacing expensive hardware.”
Frequently Asked Questions
Do I need to do any programming myself?
No. We handle the programming for you before we ship the part. The module will be flashed with the latest GM software and coded to the VIN you provide. The only thing you may need to do is a simple security relearn procedure, which typically involves cycling the key in the ignition. We provide instructions for this easy process.
How do I provide my vehicle’s VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the part to function in your car.
Will this fix my specific check engine light codes?
This PCM is a very common and effective solution for internal processor fault codes (P0601-P0606). However, while it can resolve many issues, it’s crucial to have your vehicle properly diagnosed to ensure the PCM is the root cause of the problem. This part will not fix codes related to other faulty sensors or mechanical issues.
What is the security relearn procedure?
For most GM vehicles of this era, it’s a simple process. After installing the new PCM, you’ll insert the key and turn it to the ‘ON’ position (without starting the engine) for 10-15 minutes, or until the ‘Security’ light on the dash stops flashing or turns off. Turn the key off for 10 seconds, and then repeat the cycle two more times. After the third cycle, the vehicle should start and run normally.
Where is this part located on my vehicle?
The location varies slightly by model. On the Impala, Monte Carlo, Intrigue, Aurora, and Silhouette, it’s typically found in the LH (driver’s side) engine compartment, often inside the air filter box assembly. On the Grand Am, it’s located inside the vehicle, near the center of the dash.
