Regain Command of Your 4×4 System
Is the dreaded “Service 4WD” light glaring at you from the dash? Are you stuck in two-wheel drive, unable to switch when you need it most? A failing Transfer Case Control Module (TCCM) can sideline even the most capable GM truck or SUV, leaving you without the traction and control you depend on. This is the definitive, hassle-free solution to restore your vehicle’s all-terrain capability. We provide a professionally programmed 24261367 transfer case control module, flashed with the latest GM software and tailored specifically to your vehicle’s VIN. Get back on the roadโor off itโwith confidence.
Common Symptoms & Your Direct Solution
If you’re experiencing any of the following issues, a faulty TCCM is the most likely culprit. This module is the direct-fit, pre-programmed solution for:
- “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster
- 4×4 selector switch lights are flashing or completely inoperative
- Inability to shift the transfer case into 4-High, 4-Low, or back to 2-High
- Audible clicking or grinding noises when attempting to shift the transfer case
- Diagnostic Trouble Codes (DTCs) such as C0306, C0327, C0374, or U1000
Instead of facing a costly trip to the dealership for diagnostics and programming fees, our solution puts you in control. This is more than just a part; it’s a complete, ready-to-install fix that gets your truck back to work.
From the Trenches: We had a contractor with a Sierra 2500 who couldn’t get his 4WD to engage right before a winter storm was set to hit. His job site was up a muddy, unpaved hill, and without 4×4, he was losing a full day’s work. The dealership quoted him a multi-day wait. We sent him this pre-programmed module overnight. He installed it in under an hour with basic tools and was back on the job the next morning, pulling his trailer through the snow. That’s the difference between downtime and getting the job done.

Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). Our technicians use this to download the correct, most up-to-date software from GM and flash it directly onto the module before it is shipped to you.
Is this a direct fit for my truck?
Yes. By programming the module to your specific VIN, we ensure it is a perfect electronic match for your vehicle’s options and systems. It is designed to fit and function just like the original part, covering all compatible part numbers listed.
Will this fix the “Service 4WD” light on my dash?
In the vast majority of cases, a failed TCCM is the root cause of the “Service 4WD” warning. Replacing it with this pre-programmed unit is the correct repair. However, we always recommend confirming the diagnosis, as other issues like a faulty encoder motor or selector switch can sometimes cause similar symptoms.
What tools are needed for installation?
Installation is straightforward for a DIYer with basic mechanical skills. You will typically only need a basic socket set and a trim removal tool. No special electronic or programming tools are required on your end.
Where is the TCCM located on my vehicle?
On most of the listed GM trucks and SUVs, the Transfer Case Control Module is located on the driver’s side, up under the dashboard to the left of the steering column.
What happens if I forget to send my VIN?
We cannot ship your order without the VIN, as the programming is a critical part of the product. We will contact you to request the information, but this can delay your shipment. Please provide the VIN at checkout or immediately after to ensure the fastest possible service.
