Restore Peak Performance to Your GM Vehicle
Is your 1998 Firebird, Camaro, or another GM vehicle on our list running rough, shifting erratically, or showing a persistent Check Engine Light? These are classic symptoms of a failing Powertrain Control Module (PCM), the electronic brain of your engine and transmission. Don’t let a faulty computer keep you off the road. This replacement PCM, part number 9357034, is the reliable, straightforward solution to bring your car’s drivability and efficiency back to factory standards.
Over my 20+ years in the shop, I’ve seen countless drivers frustrated by intermittent electronic issues that are notoriously hard to diagnose. A failing PCM can mimic a dozen other problems, from bad sensors to transmission failure. This module is your direct path to a definitive fix, arriving at your door programmed with the latest GM software updates specific to your vehicle’s VIN. You get a component that’s ready to install right out of the box, eliminating the need for an expensive and time-consuming trip to the dealership for programming.
Case Study: A Tricky Diagnosis
A customer brought in a ’98 Camaro with the 3.8L V6—a sister car to the Firebird that uses this exact module. The complaint was random stalling at stoplights and a hard 1-2 shift, but no consistent trouble codes. We checked fuel pressure, sensors, and the transmission fluid, all of which were fine. On a hunch, I monitored the PCM data stream and noticed the processor would occasionally drop communication for a split second. That’s the tell-tale sign of an internal PCM failure. We installed one of these pre-programmed modules, performed the security relearn, and the car ran perfectly. It saved the customer from a costly transmission exploration and got them back on the road with confidence.

Common Signs of a Failing PCM
If you’re experiencing any of the following, a faulty PCM could be the culprit. Replacing it can often resolve multiple issues at once.
- ✔ Check Engine Light is on, especially with codes like P0601, P0602, or P0605 (Internal Control Module Errors)
- ✔ Engine cranks but refuses to start
- ✔ Poor or erratic automatic transmission shifting
- ✔ Unexplained drop in fuel mileage
- ✔ Rough or unstable idle
- ✔ Stalling or hesitation during acceleration
- ✔ Failure to pass an emissions test
A Straightforward Guide to Installation
Installing your new PCM is a job most DIYers can handle in under an hour. With our pre-programming, you skip the hardest part!
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the PCM: On most of these vehicles, the PCM is located in the engine bay or under the dashboard on the passenger side. It’s a metal box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new PCM into place and securely plug in all the electrical connectors. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Security Relearn: You will likely need to perform a simple security relearn procedure (often called Passlock or VATS relearn) to sync the new PCM with your vehicle’s anti-theft system. This typically involves turning the key to the ‘ON’ position for 10-15 minutes. Instructions are readily available online for your specific model.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive an email with instructions. You can simply reply to that email with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive your VIN.
Is any other programming required after installation?
No dealership programming is needed. However, you will need to perform a simple key-cycle security relearn procedure to sync the module to your car’s anti-theft system. This takes about 30 minutes and requires no special tools.
Will this fix my specific problem?
This module corrects issues directly caused by a failing PCM. While it resolves the vast majority of electronic engine and transmission problems, it’s essential to ensure your vehicle’s other components (sensors, wiring, etc.) are in good working order.
What if I have a different service number on my original part?
This module is a fully compatible replacement for all service numbers listed in the description, including 09356741, 16236757, 9357440, and others. As long as your vehicle is on the fitment list, this part will work correctly.
