Restore Peak Performance to Your GM Vehicle
n
Is your 1999-2000 Pontiac Bonneville, Grand Prix, or other GM vehicle suffering from frustrating and unpredictable issues? Symptoms like stalling, erratic shifting, a persistent check engine light, or a complete no-start condition often point to a failing Powertrain Control Module (PCM). This vital component is the brain of your vehicle, managing everything from fuel injection and spark timing to transmission shifting. When it fails, the entire system can become unreliable. This listing is for a dependable, used OEM Powertrain Control Module, part number 09361735, which serves as a direct-fit solution to get your car running smoothly again.
nn
We take the guesswork out of the repair. Unlike a generic module from a parts store, this PCM is specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN) before it ships. This crucial step ensures that all factory settings, including anti-theft systems and specific engine/transmission parameters, are correctly configured. The result is a straightforward installation process that restores your vehicle’s original functionality and reliability without the need for an expensive trip to the dealership for programming.

From the Diagnostic Bay
n
I remember a 1999 Pontiac Grand Prix with the 3.8L V6 that came into the shop on a tow truck. The owner had spent hundreds of dollars chasing a ghost. He’d replaced the spark plugs, ignition coils, and even the mass airflow sensor, but the car would still randomly stall and refuse to restart for hours. The codes were all over the place—misfires, O2 sensor faults, communication errors. After checking the basics, we hooked up our scanner and monitored the PCM’s data stream. We saw erratic sensor readings and injector pulse widths that made no sense. It was clear the PCM itself was the source of the chaos. We installed a VIN-programmed module just like this one, performed the security relearn, and the car fired up instantly and ran perfectly. It’s a classic case where the central computer was the true culprit, making all the other components seem faulty.

Diagnosing a Faulty 1999-2000 Bonneville PCM
n
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing several of the following symptoms, your module is a likely suspect. This replacement part is designed to resolve these common issues and restore your vehicle’s proper operation.
n
- n
- ✔ Check Engine Light: The light is on, and you may have codes related to multiple, unrelated sensors or communication errors (U-codes).
- ✔ No-Start or Intermittent Start: The engine cranks but won’t start, or it starts unreliably.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and rough idling.
- ✔ Reduced Fuel Economy: A sudden and unexplained drop in your vehicle’s MPG.
- ✔ Harsh or Erratic Shifting: The transmission may shift hard, slip between gears, or get stuck in one gear (limp mode).
- ✔ Stalling: The engine may stall unexpectedly while driving or when coming to a stop.
- ✔ Failed Emissions Test: Inability to pass a smog check due to persistent engine codes or system readiness monitor issues.

VIN Programming: The Key to a Successful Repair
n
Your vehicle’s VIN is more than just a serial number; it’s a blueprint that details its specific engine, transmission, emissions equipment, and security system. By providing us with your VIN after purchase, we flash this module with the latest GM-certified software updates specific to your car. This ensures seamless communication between the new PCM and all other onboard modules, making the installation as close to plug-and-play as possible. Please note that for many GM vehicles of this era, a simple security relearn procedure may be required after installation, which can typically be done in your driveway without special tools.

Frequently Asked Questions
Is this part really plug-and-play?
Yes, because we program it with your vehicle’s VIN, it is designed to be a direct replacement. However, most GM vehicles of this period require a simple security relearn procedure (often called Passlock or Pass-Key relearn) after installation. This procedure pairs the new PCM to your car’s anti-theft system and can be done at home without any special tools. Instructions are readily available online.
Where do I send my VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship the part until we receive your VIN, as the programming is a critical step.
Is this a new part?
No, this is a high-quality, tested used OEM part sourced from a salvaged vehicle. Each unit is inspected and verified to be fully functional before being programmed and shipped. This provides OEM reliability at a fraction of the cost of a new unit.
What if my original part number is different?
GM often uses several interchangeable part numbers for the same module. As long as your vehicle’s year, make, and model are on our compatibility list, this module will function correctly once programmed to your VIN. This part, 09361735, is a common replacement for many similar modules.
Where is the PCM located on my 1999 Bonneville?
On most vehicles on this platform, including the 1999 Bonneville, the PCM is located in the engine compartment, inside the air filter box assembly on the driver’s side (LH). Always disconnect the negative battery terminal before attempting to remove or install the module.
