Is the dreaded “Service 4WD” light glaring at you from the dash? Are you unable to switch between 2WD and 4WD, leaving your truck’s full potential locked away?

It’s time for a permanent, hassle-free solution.

An Expert’s Note on Installation
“As a technician, I’ve seen countless truck owners chase this ‘Service 4WD’ issue. They replace actuators and switches, only to find the problem is the module itself. The biggest hurdle is always the programming. By providing your VIN at checkout, you’re getting a part that is truly ready to install out of the box. Double-check that your VIN is 100% correct when you send it to us. Once installed, it’s a good practice to disconnect the battery for 10-15 minutes to allow all vehicle systems to reset and recognize the new module properly. This simple step ensures a smooth and successful repair.”
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is specific to your truck.
Is this a difficult part 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 steering column. It’s typically held in with a few small bolts and has several electrical connectors. With basic hand tools, most DIY mechanics can complete the replacement in under an hour. Since our module is pre-programmed, there are no complex computer steps required after installation.
Will this fix my specific problem?
This module is the most common solution for the “Service 4WD” light and an inability to shift the transfer case. If you have scanned your vehicle and received codes related to the TCCM (like C0327), this part is the correct fix. It addresses the electronic control failure within the 4×4 system.
What if I install it and the problem remains?
While this module fixes the vast majority of 4WD electronic issues, other components like the transfer case encoder motor (actuator) or the dash selector switch can also fail. If the problem persists after installing this pre-programmed 2007-2013 Silverado 1500 Transfer Case Control Module, we recommend checking those components next. Your purchase is protected by our warranty policy.
Is this compatible with my 2500 or 3500 series truck?
Yes, this TCCM is compatible with a wide range of GM trucks and SUVs, including many Silverado/Sierra 2500 & 3500 models, as well as the Suburban, Tahoe, and Yukon. Please review the detailed fitment list in our description to confirm it matches your exact year and model.
