Restore Peak Performance to Your GM Vehicle
Is your 1998-1999 Oldsmobile Cutlass, Pontiac Grand Am, or other compatible GM vehicle suffering from perplexing issues like a persistent check engine light, poor fuel economy, erratic shifting, or a no-start condition? These are classic signs of a failing Powertrain Control Module (PCM), the central computer responsible for managing your engine’s performance and efficiency. Don’t let a faulty module keep you off the road. This direct-fit replacement PCM, part number 9357034, is the definitive solution to restore your vehicle’s original drivability and reliability.
The PCM is the brain of your vehicle’s powertrain. It processes data from dozens of sensors to precisely control fuel injection, ignition timing, transmission shift points, and emissions systems. When it begins to fail, the entire system can become unstable, leading to a cascade of performance problems. Our replacement module is meticulously prepared to integrate seamlessly with your vehicle, eliminating the guesswork and frustration of a faulty computer.

Expert Pro Tip
Before condemning your PCM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections (engine block to chassis, battery to chassis). A weak battery or a corroded ground wire can cause low voltage issues that often mimic the symptoms of a failed PCM. Ensuring your electrical system is healthy is a crucial first step in any powertrain diagnosis.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or misfiring unexpectedly.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ The engine cranks but refuses to start.
- ✔ Failure to communicate with diagnostic scan tools.
- ✔ Intermittent issues that are difficult to replicate.
Why Our 1998-1999 Cutlass PCM is the Right Choice
This isn’t just a replacement part; it’s a complete solution. The biggest challenge when replacing a modern vehicle computer is programming. This module is professionally programmed specifically for your vehicle using your unique Vehicle Identification Number (VIN). We install the latest, most stable software updates available from GM, which can often resolve factory bugs and improve overall performance beyond the original specifications. This VIN-specific programming ensures that the module communicates perfectly with all other systems in your car, from the anti-lock brakes to the instrument cluster. It arrives ready for installation, making the repair process as straightforward as possible.
This unit is a direct replacement for a wide range of GM service numbers, including 09356741, 16236757, 9356741, 9357034, 9357440, and 9366314, ensuring broad compatibility across numerous models like the Buick LeSabre, Chevrolet Malibu, Pontiac Bonneville, and many more. By providing your VIN at checkout, you guarantee a perfectly matched and updated component for your exact vehicle configuration.
The Importance of VIN Programming
In vehicles from this era, the PCM is coded to the specific options and systems of the car it came from. Simply installing a used module from another vehicle will almost certainly result in a no-start condition, incorrect transmission operation, or a host of other compatibility problems. Our mandatory VIN programming service eliminates these issues. We configure the module to recognize your engine, transmission, and emissions equipment, providing a true plug-and-play repair. Get your 1998-1999 Cutlass PCM programmed correctly the first time and avoid the headaches of an incompatible part.
