Is a “Service 4WD” Light Ruining Your Drive?
There’s nothing more frustrating than losing the all-terrain capability you rely on in your GM truck or SUV. When the four-wheel drive system fails, it’s often due to a faulty Transfer Case Control Module (TCCM). You’re left with warning lights, an unresponsive 4WD selector switch, and a vehicle that can’t tackle the tough conditions it was built for. This isn’t just an inconvenience; it’s a compromise on your vehicle’s safety and utility. Get back in control with this direct-fit, pre-programmed 24249095 GM Transfer Case Control Module.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a failing TCCM is the most likely culprit:
- “Service 4WD” or “Service Four Wheel Drive” message on the dash
- Inability to switch between 2WD, 4HI, and 4LO

- Diagnostic Trouble Codes (DTCs) such as C0306, C0321, or C0327

Expert Insight: The ‘Smart’ vs. ‘Cheap’ Repair
As a technician with over two decades of experience, I’ve seen countless truck owners try to save a few dollars by grabbing a used TCCM from a salvage yard. Here’s the problem: that used module is programmed for the donor vehicle, not yours. It simply won’t work. You’ll still have to pay a dealership or specialized shop hundreds for programming, wiping out any initial savings and adding days of downtime. This pre-flashed 24249095 GM Transfer Case Control Module is the professional’s choice because it’s the most efficient and reliable path to getting the job done right the first time.

Do I need to get this module programmed by a dealer?
No. The main benefit of this part is that we handle all the programming for you before it ships. Simply provide us with your vehicle’s VIN after purchase, and it will arrive ready for a plug-and-play installation.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to function.

This 24249095 GM Transfer Case Control Module fits a wide range of Silverado, Sierra, Suburban, Tahoe, and Yukon models. Please review the detailed fitment list on this page to confirm compatibility with your specific year, make, and model.
Where is the TCCM located on my vehicle?
On most compatible GM trucks and SUVs, the Transfer Case Control Module is located inside the cab, mounted to a bracket behind the dashboard to the left of the steering column. Access typically requires removing the lower dash panel.
What happens if I don’t provide a VIN?
The module cannot function correctly without being programmed to a specific VIN. It controls critical drivetrain functions and must be matched to your vehicle’s options and software. We will hold the order until the VIN is provided to ensure you receive a working part.
