Restore Your Truck’s Four-Wheel Drive with a Reliable, Programmed Module
As a technician with over two decades of experience under the hood of GM trucks, I’ve seen the frustration firsthand. The dreaded “Service 4WD” light illuminates your dash, and suddenly your dependable workhorse can’t switch into four-wheel drive. Whether you’re a professional mechanic diagnosing a communication fault or a DIY enthusiast stuck in 2WD before a snowstorm, a failed Transfer Case Control Module (TCCM) is often the culprit. This isn’t just an inconvenience; it’s a loss of the core capability you depend on. The TCCM is the electronic brain of your 4×4 system, and when it fails, your truck is left powerless to adapt to changing road conditions.
This replacement TCCM, part number 24261367, is the definitive solution for your 2007-2014 GMC Sierra 3500 and a wide range of other GM trucks and SUVs. The biggest hurdle with replacing these modules has always been the expensive and time-consuming trip to the dealership for programming. We eliminate that step entirely. By providing us with your vehicle’s VIN at checkout, we will flash the module with the latest, most stable GM-approved software specifically for your truck. It arrives at your door ready for a simple, direct-fit installation. This means no special scan tools, no towing fees, and no waiting for a dealership appointment. You get a reliable part that restores full functionality, programmed correctly from the start.
A Technician’s Notebook: The Misleading Diagnosis
I remember a 2011 Silverado 2500 that came into the shop. The owner was told by another garage that he needed a complete transfer case replacement—a multi-thousand dollar job. His symptoms were classic: no 4WD engagement and a persistent service light. I hooked up my scanner and found a U0102 code, ‘Lost Communication with Transfer Case Control Module.’ Instead of jumping to the most expensive conclusion, I checked the power and ground at the TCCM connector. They were perfect. This told me the module itself was the point of failure. We installed one of our pre-programmed modules, and in under 30 minutes, the truck’s 4WD system was working flawlessly. The customer saved thousands and drove away with his confidence restored. It’s a powerful reminder that proper diagnosis starts with the brain, not just the brawn, of the system.
Is Your Truck Showing These Symptoms?
A failing TCCM can manifest in several ways. If you’re experiencing any of the following, this module is the likely solution for your Sierra 3500 TCCM issues:
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the driver information center (DIC).
- ✔ Inability to shift between 2HI, 4HI, Auto 4WD, or 4LO.
- ✔ The 4WD selector switch lights are inoperative or flashing.
- ✔ The vehicle is stuck in a single drive mode (e.g., stuck in 4WD).
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as C0306, C0327, C0398, or U0102.
- ✔ Grinding or clunking noises during attempted shifts, caused by the encoder motor receiving incorrect commands.
A Straightforward Guide to Installation
One of the key benefits of this module is its simple, plug-and-play installation. No complex procedures are required. For most GM trucks, the TCCM is located on the driver’s side of the dashboard, behind the lower dash panel.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Access the Module: Carefully remove the lower dash panel beneath the steering column. It’s typically held in by a few screws and clips.
- Locate the Old TCCM: Identify the old module. It’s a small black box with several electrical connectors. It may be attached to a bracket.
- Disconnect and Remove: Unplug the electrical connectors by depressing their locking tabs. Then, unbolt or unclip the module from its mounting location.
- Install the New Module: Mount your new, pre-programmed TCCM in the same location. Reconnect all electrical connectors, ensuring they click securely into place.
- Reassemble and Test: Reinstall the lower dash panel. Reconnect the negative battery terminal. Start the vehicle and test the 4WD selector switch to confirm all modes engage correctly. The service light should be off.

Frequently Asked Questions About Your New TCCM
Frequently Asked Questions
Do I really need to provide my VIN?
Yes, this is a critical step. Your VIN allows us to load the exact GM software calibration for your truck’s specific options, ensuring perfect communication between the TCCM, engine, and transmission. This guarantees a true plug-and-play experience.
Is this a difficult part to install myself?
Not at all. For most DIYers with basic hand tools, this is a 30-45 minute job. The module is typically located in an accessible spot under the driver’s side dashboard. Our pre-programming service handles the most complex part of the job for you.
Will this fix my ‘Service 4WD’ light?
In the vast majority of cases where the TCCM is the source of the fault, yes. This module is designed to resolve communication errors and functional failures that trigger the service light. We always recommend a proper diagnosis to confirm the TCCM is the faulty component.
What if my original part number is different from 24261367?
No problem. GM often updates part numbers over time. This module is a direct replacement for all the compatible part numbers listed in the description, including 12588096, 24239190, 24249095, and more. As long as your vehicle is on the fitment list, this part will work.
Is any additional programming needed after installation?
No. The module arrives fully programmed and ready to install. Once you plug it in and reconnect your battery, it will be ready to function. There is no need for a trip to the dealer or a high-end scan tool.
