Restore Peak Performance to Your GM Vehicle
Is your 2003-2005 Chevrolet Venture, Impala, or Pontiac Grand Am suffering from baffling electrical issues, poor engine performance, or erratic transmission shifting? The Powertrain Control Module (PCM), often called the vehicle’s brain, is frequently the source of these frustrating problems. This replacement PCM, part number 89017735, is the definitive solution to restore your vehicle’s factory performance and reliability. It arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN), loaded with the latest software updates from GM. This eliminates the need for expensive dealership programming or specialized tools, getting you back on the road quickly and affordably.
From the Diagnostic Bay
We recently had a 2004 Chevrolet Impala towed in with a classic no-start condition after intermittent stalling for weeks. The owner had already replaced the battery and alternator. A quick scan revealed a hard code: P0601 – Internal Control Module Memory Check Sum Error. This code is a definitive sign of internal PCM failure. Instead of a costly trip to the dealer for a new module and programming, we ordered this exact pre-programmed unit. Once it arrived, the physical swap took less than 15 minutes. After performing the simple security relearn procedure, the car fired right up and ran smoother than it had in years. The customer saved hundreds of dollars and significant downtime.
Is Your Vehicle Showing Signs of a Faulty PCM?
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine computer may be the culprit:
- ✔ Persistent Check Engine Light (CEL) with communication-related or internal processor fault codes (e.g., P0601, P0606).
- ✔ Unexplained stalling or difficulty starting the engine, even with a good battery and starter.
- ✔ Harsh or erratic automatic transmission shifting, or getting stuck in one gear.
- ✔ A noticeable drop in fuel economy without any change in driving habits.
- ✔ Engine misfires, rough idling, or hesitation during acceleration.
- ✔ Inaccurate or non-functioning dashboard gauges.
- ✔ Failure to pass an emissions test due to readiness monitor issues.

Frequently Asked Questions
Do I need to take this part to a dealer for programming?
Absolutely not. We handle all the programming for you before the module is shipped. Simply provide us with your vehicle’s 17-digit VIN, and the part will arrive ready for installation.
What information do you need from me?
We require your vehicle’s complete 17-digit Vehicle Identification Number (VIN). You can typically find this on your driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Is this a plug-and-play installation?
Yes, for the most part. The physical installation is a direct swap. After installation, you may need to perform a simple security relearn procedure (also known as a VATS relearn), which can typically be done in your driveway without any special tools. Instructions are widely available online for this common procedure.
How can I be sure my PCM is the actual problem?
While the symptoms listed above are strong indicators of PCM failure, it’s always best to have your vehicle properly diagnosed by a qualified technician. Verifying power and ground signals to the PCM and checking for specific diagnostic trouble codes (like P0601) can confirm the diagnosis.
Will this fix my vehicle’s transmission problems?
The PCM controls both the engine and the transmission. Therefore, a faulty PCM is a very common cause of erratic shifting, delayed engagement, and other transmission-related issues. Replacing a failed PCM often resolves these problems entirely.
Is this compatible with my 2004 Pontiac Grand Am?
Yes, this module is compatible with a wide range of 2003-2005 GM vehicles, including the 2004 Pontiac Grand Am with the 3.4L engine. We program it specifically for your vehicle’s VIN to ensure perfect compatibility.
