Restore Peak Performance to Your Vehicle’s Engine
Is your 2003 Chevrolet Malibu, or another compatible GM vehicle, suffering from perplexing issues like poor fuel economy, erratic shifting, a persistent Check Engine Light, or even 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. A faulty PCM can disrupt everything from fuel injection timing to transmission control, leading to a frustrating and unreliable driving experience. This replacement Powertrain Control Module, part number 89017735, is the definitive solution to restore your vehicle’s original factory performance and reliability.
The Plug-and-Play Solution for Your 2003 Malibu PCM
Replacing an engine computer can be an intimidating task, often requiring expensive trips to the dealership for programming. We eliminate that hassle. This module is not just a part; it’s a complete, ready-to-install solution. Upon purchase, simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our certified technicians will then program the module with the latest, most stable software updates directly from General Motors. This ensures that when the part arrives at your door, it is 100% compatible with your vehicle’s specific configuration. The process is simple: unbolt the old module, plug in the new one, and you’re back on the road. No additional programming or dealer visits are required.
From the Diagnostic Bay
We once had a 2004 Pontiac Grand Am come in with what the owner was convinced was a failing transmission. It was shifting hard between first and second gear and occasionally seemed to get ‘stuck’ in a high gear, forcing a restart. He had already spent hundreds on a transmission fluid flush and diagnostics at another shop. We scanned the vehicle and found no specific transmission codes, but we did notice some erratic voltage readings from the PCM and a U-code for lost communication. Instead of tearing into the transmission, we swapped in a known-good, programmed PCM. The ‘transmission’ problem vanished instantly. It was a classic case of the PCM sending incorrect signals to the transmission control solenoids. This highlights how a failing engine computer can mimic other, more expensive mechanical failures.
Common Symptoms of a Failing Powertrain Control Module
- ✔ Persistent Check Engine Light (CEL) on your dashboard.
- ✔ Engine stalling, stuttering, or misfiring unexpectedly.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Failure to pass state emissions testing.
- ✔ Communication errors with diagnostic scan tools.

Frequently Asked Questions
How do I provide my VIN for programming?
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 essential for the part to function in your vehicle.
Is any additional programming required after installation?
No. This module arrives fully programmed to your vehicle’s VIN with the latest GM software. In most cases, it is a simple plug-and-play installation. Some GM vehicles may require a simple security relearn procedure, which takes 10-15 minutes and can be done without any special tools. Instructions are available upon request.
Will this fix my specific problem?
This PCM is a direct solution for issues caused by a faulty module. While the symptoms listed are common indicators of PCM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the PCM is the root cause of your vehicle’s problems before ordering.
Is this a new or used part?
This is a high-quality, fully tested replacement part that has been meticulously inspected and prepared to meet strict quality standards. It is programmed with fresh, vehicle-specific software to ensure optimal performance.
What if I have a different part number on my original module?
This module is a direct replacement for part numbers 89017735, 12583827, and 12583826. As long as your vehicle is on the compatibility list, this module will function correctly once programmed to your VIN, even if the number on your old part is slightly different.
