Restore Your Truck’s 4×4 Capability the Easy Way
Is that frustrating “Service 4WD” light glaring at you from the dash of your 2008-2013 Chevy Avalanche? Are you unable to switch between 2WD and 4WD, or hearing unsettling noises when you try? You’re not alone. The Transfer Case Control Module (TCCM) is the electronic brain of your four-wheel-drive system, and when it fails, it can leave your capable truck stuck in two-wheel drive. Dealerships will often charge a premium for the part, plus significant labor and programming fees. We offer a smarter, more direct solution.
This is a genuine replacement TCCM, part number 24261367, that arrives at your doorstep fully programmed to your vehicle’s specific VIN. We load the latest GM-certified software before it ships, making this a true plug-and-play fix. No need for expensive scan tools or a trip to the dealer. You get a reliable part that communicates flawlessly with your truck’s systems, restoring the function and peace of mind you depend on.
From the Diagnostic Bay
I remember a 2011 Silverado that came into my shop with the classic “Service 4WD” light and the selector switch completely dead. The owner was worried about a costly transfer case repair. After a quick scan, I pulled code U0102 – Lost Communication with Transfer Case Control Module. Instead of jumping to conclusions, I checked the TCCM’s power and ground at the connector—they were perfect. This told me the module itself had failed internally, a common issue I’ve seen on hundreds of these GM trucks. We installed a VIN-programmed module just like this one, and in under 30 minutes, the 4WD system was back online, saving the customer hundreds compared to the dealership quote.
Is Your Avalanche 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 2008-2013 Avalanche TCCM issues:
- ✔ “Service 4WD” or “Service Four Wheel Drive” message on the instrument cluster.
- ✔ The 4WD selector switch lights are inoperative or flashing.
- ✔ Inability to shift the transfer case into 4HI, 4LO, or back to 2HI.
- ✔ Grinding or clunking noises when attempting to shift the transfer case.
- ✔ Diagnostic Trouble Codes (DTCs) stored in the system, such as C0306, C0327, C0569, or U0102.
A Straightforward Guide to Installation
Replacing the TCCM on your Avalanche is a job most DIYers can handle with basic tools. Our pre-programming service eliminates the most difficult step. Here’s a general guide:
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts.
- Locate the Module: The TCCM is typically located on the driver’s side of the dashboard, up and to the left of the steering column. You may need to remove the lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed TCCM into place. Firmly reconnect the electrical harnesses, ensuring they click securely into place.
- Final Steps: Reinstall the dash panel, reconnect the negative battery terminal, and start the vehicle. Test the 4WD selector switch to confirm proper operation. The “Service 4WD” light should be gone!
