Frequently Asked Questions
Do I need to do any programming myself?
No. This module comes fully programmed to the VIN you provide. In most cases, it is a simple plug-and-play installation. You may need to perform a simple security relearn procedure, which involves cycling the key and takes about 30 minutes. We provide instructions for this.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will send you an email requesting your vehicle’s 17-digit VIN. Simply reply to that email, and our technicians will handle the rest. We cannot ship your part until we receive the VIN.
Is this the correct part for my vehicle?
This module fits the vehicles listed in the compatibility chart. Please verify that your original part number is on our cross-reference list. If you are unsure, please contact us with your VIN before ordering, and we will be happy to confirm the fitment for your specific 2006 Trailblazer PCM 12589585.
What is the security relearn procedure?
For many GM vehicles, the security system needs to relearn the new module. The standard procedure is to turn the key to the ‘ON’ position for 10 minutes, then ‘OFF’ for 10 seconds, and repeat this cycle three times. This allows the BCM (Body Control Module) to recognize the new PCM.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls both the engine and the transmission. If the module’s internal transmission controller has failed, it can cause harsh shifting, delayed engagement, or incorrect gear selection. This replacement unit will correct those issues if they originate from the computer.
What if my original part number is not on your list?
The provided list covers the most common compatible part numbers. However, GM often releases new numbers. If you don’t see your specific part number, please send us a message. We can verify compatibility to ensure you receive the correct module for your vehicle.
