Restore Peak Performance to Your 3.8L V6
Is your 1998 Chevrolet Camaro or another GM vehicle from this era running rough, shifting erratically, or showing a persistent Check Engine Light? The Powertrain Control Module (PCM) is the central computer of your vehicle, orchestrating everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This replacement Powertrain Control Module is the definitive solution to get your vehicle running reliably again.
This isn’t just a generic, off-the-shelf part. We provide a fully programmed module specific to your vehicle. Upon purchase, simply provide us with your Vehicle Identification Number (VIN), and our technicians will flash the unit with the latest, most stable software updates directly from GM. This critical step ensures seamless communication with your vehicle’s other modules, correct engine and transmission parameters, and a true plug-and-play installation experience, minimizing post-installation headaches.
From the Diagnostic Bay
We had a 1998 Pontiac Firebird with the 3.8L V6 come into the shop with a complaint that was driving the owner crazy. The car would randomly stall at stoplights, but only when the engine was fully warmed up. It would also occasionally have a hard, jarring shift from first to second gear. There were no consistent trouble codes, just a generic P0300 random misfire code that would pop up now and then. We checked the fuel pressure, spark plugs, wires, and even the crankshaft position sensor. Everything checked out. On a hunch, we connected a scope to the injector control signals coming from the PCM. We noticed that after about 20 minutes of driving, the signal to injector #3 would start to drop out intermittently. The heat soak was causing a component inside the original PCM to fail. We installed one of our pre-programmed modules, performed the security relearn, and the car ran perfectly. It’s often these intermittent, heat-related issues that point directly to a failing PCM.
Common Symptoms of a Failing 1998 Camaro PCM
A faulty PCM can manifest in numerous ways. If you’re experiencing any of the following issues, a failing engine computer could be the culprit. This module is a direct replacement for service numbers 09356741, 16236757, 9357034, 9357440, and 9366314.
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Rough or erratic idling.
- ✔ Poor fuel economy.
- ✔ Harsh or delayed automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Failure to pass state emissions testing.
- ✔ Intermittent loss of communication with diagnostic scan tools.
Why VIN Programming is Essential
In modern vehicles, the PCM is not a one-size-fits-all component. It must be calibrated for your car’s specific engine, transmission, emissions equipment, and even tire size. Our VIN-based programming service ensures that the module you receive is an exact match for your vehicle’s original factory specifications. This eliminates compatibility conflicts and ensures all systems function as the manufacturer intended. Installing a non-programmed or incorrectly programmed module can lead to further drivability issues or even prevent the vehicle from starting at all due to anti-theft system conflicts.
Broad GM Compatibility
While this is a perfect solution for the 1998 Camaro PCM with the 3.8L V6, this versatile module also fits a wide range of other GM vehicles from the same era. Please verify your service number and check the compatibility list below to ensure a perfect match for your car.

Frequently Asked Questions
Do I need to do anything after installing this PCM?
Because this module is pre-programmed to your VIN, it is nearly plug-and-play. However, on most GM vehicles of this era, you will need to perform a security relearn procedure (often called VATS relearn) to sync the module with your key’s anti-theft chip. This procedure is simple, requires no special tools, and instructions can easily be found online. A Crankshaft Variation Relearn (CASE) may also be required, which can be done with a capable bidirectional scan tool.
Where do I provide my VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship the module until we receive this information, as the programming is the most critical step of the process.
Is this a brand new part?
This is a high-quality, genuine GM replacement part that has been thoroughly inspected, tested, and prepared to meet or exceed original factory specifications. It is programmed with the latest GM software for optimal performance and longevity.
What if my original service number isn’t on the list?
The service numbers listed (09356741, 16236757, etc.) are the most common compatible units. If your number is different, please contact us with your VIN and original part number. We can verify compatibility and ensure you receive the correct module for your vehicle.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM also functions as the Transmission Control Module (TCM) in these vehicles. It controls shift solenoids and line pressure. If your shifting issues are electronic in nature and not caused by an internal mechanical failure of the transmission, a replacement PCM is often the solution.
