Is Your Truck Running Rough? Get the Right Fix, The First Time.
If your Silverado, Sierra, or other GM truck is suffering from a persistent check engine light, erratic shifting, stalling, or a frustrating no-start condition, the root cause is often a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, its proper function is critical. This replacement PCM, service number 89017734, is the definitive, hassle-free solution to restore your vehicle’s performance and reliability.
Common Symptoms & Your Solution
A faulty PCM can cause a wide range of confusing symptoms. You might be experiencing:
- Check Engine Light with codes like P0601, P0602, or P0606
- Poor or declining fuel economy
- Engine stalling or cutting out unexpectedly
- Rough idling or hesitation during acceleration
- Failure to pass emissions testing
- Harsh or incorrect transmission shifting
Instead of guessing with sensors or wiring, address the core of the problem. Our Programmed 89017734 PCM arrives at your door ready for installation. We take care of the complex part by flashing the module with your vehicle’s specific VIN and the latest software updates from GM, ensuring a perfect match and seamless integration with your truck’s systems.

Expert Insight: Why Pre-Programming is Essential
From our lead technician: “Many truck owners chase down sensor and wiring issues for weeks, only to find the PCM was the root cause all along. A common sign of internal PCM failure on these GM trucks is a P0601 ‘Internal Control Module Memory Check Sum Error’ code. Simply swapping in a used module from a salvage yard won’t work because of the factory anti-theft system (VATS/Passlock). Our service provides a fully tested Programmed 89017734 PCM that is correctly configured for your VIN, saving you the significant time, cost, and headache of a dealership visit for programming and security relearning.”

Frequently Asked Questions
Do I need to take this to a dealer for programming?
Absolutely not. We handle all the programming before we ship the part to you. All we need is your vehicle’s VIN to load the correct GM factory software. This saves you from paying expensive dealership programming fees.
How do I provide my VIN number?
After you complete your purchase, we will contact you for your VIN. You can also add your vehicle’s VIN as a note during the checkout process to speed up your order.
Is this a simple plug-and-play installation?
Yes, for the most part. Once you install the new PCM, you may need to perform a simple security relearn procedure, also known as a VATS relearn. This procedure syncs the new PCM with your vehicle’s anti-theft system and can be done in your driveway in about 15-30 minutes with just your key. We can provide instructions for this simple process.
What if my original part number is different from 89017734?
This is very common. GM uses many different service numbers for the same compatible part. This Programmed 89017734 PCM is a direct replacement for several other numbers, including 89017750, 12582605, 12589463, and 12602802. As long as your vehicle is on our fitment list, this unit will work perfectly.
What does the PCM actually do?
The Powertrain Control Module (PCM), sometimes called an Engine Control Module (ECM), is the main computer for your vehicle. It controls critical functions like fuel injection, ignition timing, transmission shifting, and emissions systems to ensure your engine runs efficiently and reliably.
