From the Technician’s Bench
“We’ve seen countless truck owners spend hundreds, sometimes thousands, chasing down sensor and wiring issues when the true culprit was a failing PCM. Intermittent communication faults or random misfire codes that move between cylinders are classic signs that the vehicle’s ‘brain’ is struggling. Before you replace another sensor, consider the source. A correctly programmed GM 89017749 PCM often resolves these phantom issues instantly, saving you time, money, and immense frustration.”
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will provide us with your vehicle’s 17-digit VIN. We then use that information to load the correct, updated GM-certified software onto the module. This ensures it is a perfect match for your vehicle’s engine, transmission, and options.
Will I need to do anything after installation?
In most cases, the module is ready to go upon installation. However, some vehicles may require a security relearn procedure (often called a CASE relearn or anti-theft relearn), which can typically be done without special tools. Instructions for this simple procedure are widely available online for your specific model.
Is this the correct part for my vehicle?
This GM 89017749 PCM fits a wide range of models listed in the compatibility chart. The best way to confirm is to match the part number from your original module. If you are unsure, please provide your VIN and we can verify fitment for you.
What information do you need from me?
We only need your vehicle’s VIN (Vehicle Identification Number) to program the module. Please double-check it for accuracy before sending it to us to ensure a flawless programming process.
Do you need my old part back?
No core charge is required for this part. You do not need to send your old module back to us.
