Expert Tech Tip: The number one reason for a failed PCM replacement is improper programming. On these GM trucks, the PCM is tied directly to the vehicle’s anti-theft system (PassLock/VATS). Simply installing a used computer from another vehicle will result in a no-start condition. Our VIN-specific programming service ensures the module communicates perfectly with your truck’s security, ignition, and other systems right out of the box, making your repair job a success from the start.
This is more than just a part; it’s a complete, ready-to-install solution. By providing us with your VIN during checkout, you ensure that the programmed 2006 Trailblazer PCM you receive is perfectly matched to your vehicle’s factory specifications. Get your reliable GM truck back on the road with confidence.
Frequently Asked Questions
Do I need to do any additional programming after installation?
No. This PCM comes fully programmed to your vehicle’s VIN. In most cases, it is a simple plug-and-play installation. However, some vehicles may require a security relearn procedure, which is a simple process that can be done without any special tools. Instructions are readily available online or we can provide them.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Where is the PCM located on my 2006 Trailblazer?
On the 2006 Trailblazer, Envoy, and Rainier with the 4.2L engine, the PCM is located on the driver’s side of the engine block, below the intake manifold. It has several large electrical connectors.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls both engine and transmission functions. If your shifting issues are caused by faulty electronic signals from the computer, this new unit will resolve them. However, it will not fix internal mechanical problems within the transmission itself.
Is this the correct part for my vehicle?
This module fits a variety of 2004-2006 GM trucks and SUVs as listed in the fitment guide. It replaces numerous original part numbers. Please verify your vehicle’s make, model, year, and engine match the compatibility list. Programming with your VIN ensures it works specifically for you.
