Is your Mercedes refusing to shift out of Park? When the Intelligent Servo Module (ISM/DSM) fails, your luxury vehicle becomes an immovable object. The dealership’s answer is a brand-new unit and a massive bill for online SCN coding. At ClusterFix Texas, we offer the "Best of Both Worlds": a precision data clone that moves your car’s unique security handshake from your failed module to a healthy one.
The Experiential Truth of a Seamless Repair
Imagine the relief of simply bolting your cloned ISM back onto the transmission, clearing the codes, and feeling your Mercedes click into gear exactly as it should. No "Component Protection" lockouts, no expensive dealership programming, and no more being stranded. Whether you're in the heart of San Antonio or out in West Texas, we provide a 100% plug-and-play solution that lets you skip the dealer drama.
