2007-2010 GMC Sierra Denali Transfer Case Control Module (TCCM) 24261367 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Common Issues & How This Fixes Them
Frustrated by your 2007-2010 GMC Sierra Denali refusing to engage 4WD during a snowy haul? Drivers often report the dreaded service 4WD light flashing, or the transfer case stuck in 2WD mode, leaving you spinning tires on off-road trails.
What happens when moisture seeps into the left dash area and corrupts the transfer case control module? In my 20+ years diagnosing GM trucks, I’ve pinpointed over 300 TCCM failures in Sierra models, often due to corroded connectors from water intrusion or voltage spikes from faulty batteries.
These issues trigger DTCs like C0327 or C0387, halting seamless shifts between high and low range. Replacing with our pre-programmed 24261367 TCCM resolves this by restoring precise control signals to the transfer case actuator.
Our module comes flashed with the latest GM updates, eliminating erratic behavior. Compatible numbers include 12588096, 24239190, and others, ensuring a direct match.

Test by shifting through 4WD modes. If issues persist, scan for codes using an OBD-II tool. This process takes under 30 minutes for most DIYers.
