Is your GM truck or SUV giving you headaches?
If you’re dealing with a persistent check engine light, erratic engine behavior, poor shifting, or even a no-start condition, a failing Powertrain Control Module (PCM) is likely the culprit. These issues can bring your reliable workhorse to a standstill, leading to frustrating diagnostic chases and expensive repair bills. This programmed 89017750 PCM is the direct, reliable solution to restore your vehicle’s performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty PCM can manifest in various ways, often mimicking other sensor or component failures. If you’re experiencing any of the following, this module is your definitive fix:
- Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, P0605, or P0606.
- Engine Stalling or Misfiring: Unexplained stalling at idle or misfires under load.
- Harsh or Erratic Shifting: The transmission may shift poorly, late, or not at all.
- No-Start Condition: The engine cranks but will not start, often due to a lack of fuel injector or ignition coil command.
- Poor Fuel Economy: A failing module can’t efficiently manage the engine, leading to a noticeable drop in MPG.
This isn’t just a replacement part; it’s a complete solution. We program this programmed 89017750 PCM to your vehicle’s specific VIN, ensuring it arrives ready to install with the latest factory software updates from GM. This process eliminates the need for an expensive trip to the dealership for programming.

Frequently Asked Questions
Do I need to get this programmed by a dealer?
No! The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. It arrives ready for installation, saving you the time and expense of a dealership visit.
Is this a simple plug-and-play installation?
For most vehicles, yes. You disconnect the battery, swap the modules, and reconnect the battery. In some cases, you may need to perform a security relearn procedure (also known as a CASE relearn or anti-theft relearn), which is a simple process that can be done without special tools. Instructions are widely available online for your specific model.
How do I provide my VIN?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information to ensure correct programming.
Will this fix my check engine light?
If your check engine light is caused by an internal failure of the PCM (common codes include P0601, P0602, P0606), then this part is the correct solution. However, we always recommend having your vehicle properly diagnosed by a professional before ordering to confirm the PCM is the point of failure.
