Expert Insight: The Real Cost of a Failed TCCM
“We had a customer with a 2012 Sierra 3500 Dually who was about to haul his fifth-wheel trailer up a steep mountain pass for a family vacation. The day before he was set to leave, his ‘Service 4WD’ light came on, and he was stuck in 2WD. The dealer quoted him a 3-day wait time and a hefty bill for diagnostics and programming. He ordered our pre-programmed 2011-2014 Sierra 3500 Transfer Case Control Module with expedited shipping. It arrived the next morning, he installed it in under 20 minutes in his driveway, and his 4WD system was fully functional. He made his trip without a hitch. It’s not just about fixing a part; it’s about avoiding costly downtime and keeping your plans on track.”
