Get Your Truck Back on the Road, Fast.
Is your truck or SUV plagued by frustrating, hard-to-diagnose issues? Stalling at stoplights, erratic shifting, a persistent Check Engine Light, or a complete no-start condition can all point to a failing Powertrain Control Module (PCM). Don’t let a faulty engine computer keep your reliable workhorse off the road. This replacement Programmed 89017734 PCM is the definitive, hassle-free solution to restore your vehicle’s performance and dependability.
Common Symptoms & Your Solution
A failing PCM can cause a wide range of problems that can be mistaken for other component failures. If you’re experiencing any of the following, a faulty engine computer is the likely culprit:
- Persistent Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs) like U0100.
- Engine stalling, sputtering, or misfiring.
- Harsh or unpredictable automatic transmission shifting.
- Reduced fuel economy and poor engine performance.
- Complete no-start condition where the engine cranks but won’t fire.
This module is the solution. We take the guesswork out of the repair by pre-programming the unit to your vehicle’s specific Vehicle Identification Number (VIN). This ensures it communicates perfectly with your vehicle’s existing systems right out of the box, saving you a costly and time-consuming trip to the dealership for programming.

Expert Insight: The Critical Role of Correct Programming
As a technician with over two decades of experience, I’ve seen countless vehicle issues caused by improperly matched control modules. Simply swapping a used PCM from another vehicle will almost never work. Modern vehicles use a complex communication network (CAN bus) where each module is coded specifically to the VIN. Our professional programming service ensures this Programmed 89017734 PCM is a true digital clone of your original, preventing security lockouts, communication errors, and a host of other issues. This isn’t just a part; it’s a complete, ready-to-install solution that gets the job done right the first time.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program or ship your module until we receive this information.
Is any additional programming needed after installation?
In most cases, no. The unit comes fully programmed. However, many GM vehicles of this era require a security relearn procedure (often called a CASE relearn or anti-theft relearn) after installation. This is a simple procedure that can typically be done without special tools and takes about 30 minutes. Instructions can be readily found online for your specific model.
Is this a plug-and-play part?
Yes, after the required security relearn procedure is completed, it is a plug-and-play installation. The module is programmed to your VIN, so you just need to disconnect the battery, swap the old module for the new one, reconnect the battery, and perform the security relearn.
How can I be sure this fits my vehicle?
This Programmed 89017734 PCM is compatible with a wide range of GM trucks and SUVs. Please cross-reference the service numbers listed (89017750, 12582605, 12589463, etc.) and check the detailed fitment list on this page to confirm compatibility with your specific year, make, and model.
