Is Your Truck’s 4WD System Acting Up?
Seeing the dreaded “Service 4WD” light on your dash? Can’t switch between 2WD and 4WD, or hearing strange noises from your transfer case?

- Inability to shift the transfer case into or out of 4-High, 4-Low, or Auto.
- Selector switch lights are blinking or not illuminating at all.
- Diagnostic Trouble Codes (DTCs) such as C0306, C0327, C0374, or others related to the transfer case system.

An Expert’s Note: We had a customer with a 2011 Sierra 2500 who was stuck in 4-High right before a long road trip. The local dealer quoted him over $700 for a new module plus programming and a two-day wait. He ordered our Programmed Transfer Case Control Module 24242480, sent us his VIN, and had the part in hand the next day. In less than 30 minutes, he swapped the module himself in his driveway and his 4WD system was working flawlessly. That’s the real-world value of a part that’s ready to install right out of the box.
Don’t settle for a 2WD truck when you own a 4×4. This is the most efficient and reliable way to solve your transfer case electronic issues and get your vehicle’s all-terrain capability back.

Frequently Asked Questions
What does the Transfer Case Control Module (TCCM) do?
The TCCM is the electronic “brain” of your vehicle’s four-wheel-drive system. It receives input from the driver via the 4WD selector switch and commands the transfer case motor to shift the vehicle into the desired drive mode (e.g., 2WD, 4WD High, 4WD Low).
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific configuration and the latest software into the module. Without it, the TCCM won’t be able to communicate correctly with your truck’s engine, transmission, and ABS controllers, leading to error messages and a non-functional 4WD system. Our service saves you a mandatory, and often costly, trip to the dealership.
Is this module difficult to install?
For most of the listed GM trucks and SUVs, the TCCM is located under the driver’s side of the dashboard, to the left of the steering column. It’s typically held in by a few bolts or clips and has several electrical connectors. Most DIYers with basic tools can complete the installation in under an hour.
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 your order until we receive this information, as the programming is a critical step in the process.
Will this fix a mechanical problem with my transfer case?
This module corrects electronic failures. If your transfer case has internal mechanical damage, such as a broken chain or worn gears, this part will not solve that issue. It’s important to properly diagnose the problem or have it checked by a professional if you suspect mechanical failure.
