Restore Full Control of Your Truck’s 4WD System
As a technician with over two decades of experience under the hood of GM trucks, I’ve seen the frustration that a flashing “Service 4WD” light can cause. When your 2007-2014 Silverado 3500 Pickup refuses to shift into four-wheel drive, or gets stuck in it, the problem often points directly to a failed Transfer Case Control Module (TCCM). This isn’t just an inconvenience; it’s a critical failure that can leave you stranded in tough conditions. This module is the electronic brain of your 4×4 system, and when it goes, your truck’s legendary capability goes with it.
We offer a dependable and straightforward solution: a replacement TCCM, part number 24261367, that arrives at your door fully programmed to your vehicle’s specific VIN. By handling the programming with the latest GM software updates before we ship, we eliminate the most expensive and time-consuming part of the repair. You get a part that’s ready for installation right out of the box, restoring your truck’s function without a mandatory trip to the dealership. This is the exact approach I’d take in my own shop to get a customer’s truck back on the road or trail quickly and reliably.
A Technician’s Notebook
I remember a 2011 Silverado 2500 that came into the bay with a classic complaint: the 4WD selector switch was dead, and the truck was stuck in 2-Hi. The owner had just bought it for his contracting business and needed it for muddy job sites. The scan tool was throwing a U0102 code—Lost Communication with Transfer Case Control Module. After verifying power and ground at the TCCM connector, it was clear the module itself was the culprit. Instead of a costly dealer part and programming appointment, we installed one of these pre-programmed units. The entire job took less than 30 minutes. The moment we reconnected the battery, the selector switch lit up, and the transfer case shifted flawlessly through all ranges. The customer was back in business the same day, a perfect example of how the right part, correctly prepared, makes all the difference.
Is Your Truck Exhibiting These TCCM Failure Signs?
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster.
- ✔ Inability to switch between 2WD, 4-Hi, 4-Lo, or Auto modes.
- ✔ The 4WD selector switch lights are off or flash without engaging.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as U0102 (Lost Communication With TCCM).
- ✔ Grinding or clunking noises when attempting to shift the transfer case.
- ✔ The vehicle is permanently stuck in one drive mode (e.g., 4-Hi).
A Straightforward Guide to Installation
Replacing the 2007-2014 Silverado 3500 TCCM is a job most DIYers can handle with basic tools. Since we’ve pre-programmed it to your VIN, no special scanners are needed.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: On most of these GM trucks, the TCCM is located on the driver’s side of the dashboard, usually up and to the left of the steering column, often attached to a metal bracket.
- Remove Trim Panels: You may need to remove the lower dash panel below the steering wheel to gain access. These panels are typically held in by a few screws and clips.
- Unplug and Unbolt: Carefully disconnect the electrical connectors from the old module. They have locking tabs that need to be depressed. Then, remove the nuts or bolts holding the module to its bracket.
- Install the New TCCM: Mount your new, pre-programmed TCCM onto the bracket and securely fasten it. Reconnect the electrical connectors, ensuring they click into place.
- Reassemble and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Turn the ignition to the ‘On’ position (without starting the engine) and test the 4WD selector switch. You should see the indicator lights function correctly and hear the transfer case actuator engage as you switch modes.

Frequently Asked Questions
Why do I need to provide my VIN?

Is this a plug-and-play part?
Yes! Because we program it to your VIN before shipping, it is a true plug-and-play solution. No further programming or dealer visits are required for installation.
Will this fix my “Service 4WD” light?
If the TCCM is the source of the problem, then yes, this part will resolve the issue and turn off the warning light. Common symptoms of a bad TCCM include a non-responsive 4WD switch and communication error codes like U0102.
Where is the TCCM located on my 2012 Silverado 3500?
On the 2007-2014 GM trucks and SUVs, the TCCM is typically found inside the cab, mounted to a bracket on the driver’s side, high up in the dash to the left of the steering column.
What tools do I need for the installation?
You’ll generally need basic hand tools, such as a socket set (commonly 7mm and 10mm sockets), a ratchet, and possibly a trim removal tool to safely pry off the lower dash panel without causing damage.
