Restore Your 4WD with a Plug-and-Play Solution
Is the dreaded “Service 4WD” light staring you down from the dashboard? Are you frustrated by a four-wheel-drive system that won’t engage, disengage, or responds erratically to the selector switch? You rely on your truck or SUV to perform in all conditions, and a faulty Transfer Case Control Module (TCCM) can leave you without the capability you need. This module is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN, eliminating the need for an expensive trip to the dealership for programming.

- 4WD selector switch lights are flashing or not illuminating at all
- Vehicle feels stuck in a specific 4WD mode
- Diagnostic Trouble Codes (DTCs) such as C0306, C0321, C0327, C0398, or U0102

An Expert’s Note on TCCM Failure
“I’ve seen it hundreds of times. A customer comes in, worried about a huge repair bill because their Silverado is stuck in 4-Low, or their Tahoe won’t engage 4WD right before a big snowstorm. In the vast majority of these GMT900 platform trucks, the issue traces back to this exact module. Internal electronic components fail over time from heat and vibration. The real win for our customers is getting a programmed transfer case control module that’s ready to go out of the box. It turns a potential multi-day dealership headache into a simple, 30-minute fix in their own driveway.”
Don’t let a small electronic part sideline your powerful truck or SUV. This is the smart, efficient way to solve your 4WD problems and get your vehicle back to 100% capability. By providing us with your VIN at checkout, you ensure that the programmed transfer case control module you receive is a perfect electronic match for your vehicle’s specific configuration.
Frequently Asked Questions
Why is VIN programming so important for this part?
The TCCM communicates with your vehicle’s other computers, like the Engine Control Module and Body Control Module. Programming it with your specific VIN ensures it has the correct software and settings for your truck’s options (like transfer case type, axle ratios, and tire size) to work seamlessly and without errors.
Is this a difficult part to install?
No, this is generally considered a simple installation. The module is typically located under the driver’s side of the dashboard. It involves removing a few trim panels for access, unplugging the electrical connectors from the old module, and plugging them into the new one. No special tools are typically required.
How do I provide my VIN number?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information to complete the programming.
Will this fix my “Service 4WD” light?
In the vast majority of cases where the TCCM has failed, yes. This module is the most common cause of that warning light on these GM vehicles. Once installed, the light should go out, and your 4WD system should function correctly.
Is this compatible with my 2007 Sierra/Silverado?
Yes, this fits the 2007 “new style” (NBS) trucks, which are identifiable by a smooth door skin without a plastic crease/body line in the middle. It does not fit the 2007 “classic” body style.
