Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is a critical step.
Is this part difficult to install?
For most of the listed GM trucks and SUVs, the TCCM is located on the driver’s side, up under the dashboard near the parking brake pedal. It’s typically held in by a few bolts or clips and has several electrical connectors. Installation is straightforward for someone with basic mechanical skills. Since it comes pre-programmed, no special tools are needed after the physical installation.
What if I install it and my 4WD still doesn’t work?
While this module is the most common cause of 4WD system failure, other components like the transfer case encoder motor, the selector switch, or wiring can also be at fault. We recommend performing a full diagnostic if you are unsure. However, this module resolves the vast majority of electronic 4WD issues.
How can I be sure this fits my truck?
Please review the detailed fitment list in this description. The most reliable method is to match your old part number to one of the compatible numbers listed. Providing us with your VIN for programming also allows us to double-check for compatibility before we ship.
Does this module require any additional setup after installation?
No. Because we program it to your VIN before shipping, it is a true plug-and-play part. Simply disconnect the battery, swap the old module with the new one, reconnect the battery, and your 4WD system should be fully functional again.
