Get Your 4WD System Back in Command
Is that frustrating “Service 4WD” light staring you down from the dashboard? If your Silverado, Sierra, or GM truck is refusing to switch into four-wheel drive, leaving you without the traction you depend on, the problem often lies with a failed Transfer Case Control Module (TCCM). Don’t let a faulty electronic module compromise your truck’s capability. This direct-replacement TCCM is the definitive, hassle-free solution to restore full control and get you back on the road, trail, or job site with confidence.
Common Symptoms & Your Solution
A failing TCCM can bring your truck’s advanced 4×4 system to a halt. You’re not just buying a part; you’re buying a solution to common problems like:
- The “Service 4WD” or “Service Four Wheel Drive” message is constantly on.
- Inability to switch between 2HI, 4HI, and 4LO modes.
- The selector switch lights don’t illuminate or flash without engaging.
- Diagnostic Trouble Codes (DTCs) such as C0327, C0306, C0374, or U1000 are present.
This module is the answer. We take the guesswork and dealership expense out of the equation by pre-programming it to your vehicle’s specific VIN before it ever leaves our facility.

An Expert’s Insight on TCCM Failure
As a technician, I’ve seen dozens of these GMT900-platform trucks come in with 4WD issues. More often than not, the culprit is this TCCM. Located under the dash, they are susceptible to electronic failure over time. In the past, a replacement meant a new module, installation, and then a mandatory trip to the dealer for programming with their proprietary tools—a process that could easily add hundreds in labor and fees. Offering a VIN-programmed 2007-2014 Silverado 2500 Transfer Case Control Module completely changes the game for the DIYer or independent shop. It turns a multi-step, expensive repair into a straightforward component swap you can do in your own garage, saving significant time and money.
Frequently Asked Questions
Do I need to take this module to a dealer for programming?
Absolutely not. The main benefit of this module is that we program it to your vehicle’s VIN before we ship it. It will arrive ready for installation, with no further programming required.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive this information, as the programming is specific to your truck.
Is this a guaranteed fit for my truck?
This module fits a wide range of 2007-2014 GM trucks and SUVs. Please carefully review the detailed fitment list on this page to confirm that your specific year, make, model, and transfer case option are listed.
What tools are needed for installation?
Installation is typically straightforward for those with basic mechanical skills. It involves accessing the module (usually located on the driver’s side, to the left of the steering column), disconnecting the battery, removing a few electrical connectors, and swapping the unit. Basic hand tools like a socket set are usually all that is required.
Will this fix my “Service 4WD” light?
If the light is caused by a faulty TCCM, then yes, this part is the correct solution. The TCCM is the most common point of failure for these symptoms. However, we always recommend a proper diagnosis to rule out other potential issues like a faulty encoder motor, selector switch, or wiring problems.
