Real-World Repair Story
I remember a 2011 Silverado 2500 that was towed into my shop. The owner was convinced he needed a new transfer case, a repair that can run into the thousands. His truck was stuck in 4-Hi, making tight turns in parking lots a nightmare of tire-hopping and binding. He couldn’t get it to shift into 2WD. After a quick scan, I found a U0102 code—’Lost Communication with TCCM.’ Instead of a massive mechanical job, the fix was a new TCCM. In his case, we had to program it on-site. With this module, that customer could have ordered it online, plugged it in himself, and saved a tow bill, diagnostic fees, and hundreds on the repair. That’s the value of a pre-programmed part.
