Get Your 4WD System Working Flawlessly Again
Is that nagging “Service 4WD” light on your dash driving you crazy? Are you unable to switch into four-wheel drive, leaving you unprepared for bad weather or tough terrain? A faulty Transfer Case Control Module (TCCM) is often the culprit, acting as the brain for your vehicle’s 4×4 system. This isn’t just an inconvenience; it’s a loss of the core capability and confidence you expect from your GM truck or SUV. We have the definitive, hassle-free solution to get you back in control.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a failing TCCM is the likely cause:
- “Service 4WD” or similar warning message on the instrument cluster
- Inability to shift between 2HI, 4HI, and 4LO
- 4WD selector switch has no lights or is unresponsive
- Grinding or clunking noises during attempted shifts
- Diagnostic Trouble Codes (DTCs) such as C0306, C0327, C0374, or C0569

Expert Insight: The Smart Fix for a Common Failure
As a technician, I’ve seen dozens of these GMT900-platform trucks and SUVs come in with 4WD issues. The original TCCMs are prone to internal electronic failure over time, often from voltage spikes or simple component aging. The old-school fix was to grab a used module and pay a dealer upwards of $150 to *try* and program itโa process that often failed. Our solution is far superior. By providing a quality module that is pre-flashed with clean, updated software matched to your VIN, we eliminate all the guesswork. You’re not just buying a part; you’re buying a guaranteed solution that gets the job done right the first time, just like a professional shop would.
Take back the full capability of your truck. This Programmed Transfer Case Control Module 24242480 is your key to a simple, effective, and lasting repair. Don’t wait for the first snowfall or the next muddy road to wish you had functional 4WD. Order today and install with confidence.
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 VIN to load the exact, correct GM software and calibrations for your specific truck or SUV onto the module before we ship it to you.
Is this part truly plug-and-play?
Yes. Because we program the module to your VIN before shipment, it is ready for installation right out of the box. Simply disconnect the battery, remove your old TCCM, install the new one, reconnect the battery, and you’re done. No further programming or dealer visits are required.
Will this fix my “Service 4WD” light?
If the warning light is being caused by a faulty TCCM (which is the most common reason), then yes, this part will resolve the issue and turn off the light after installation. We always recommend having the codes scanned to confirm the diagnosis before ordering.
My original module has a different part number. Will this still work?
Yes, most likely. This module is a compatible replacement for all the part numbers listed in the description, such as 24261367, 24249095, and others. As long as your original part number is on our list, this unit will work perfectly once programmed for your vehicle.
Where is the TCCM located on my vehicle?
On most compatible models like the Silverado, Sierra, Suburban, and Tahoe, the Transfer Case Control Module is located behind the lower dashboard panel on the driver’s side (LH dash), to the left of the steering column.
