Safe-T-Shift guards against driveline damage

Marmon-Herrington Co has introduced the Safe-T-Shift, which prevents drivers of heavy-duty trucks from shifting at the wrong time. The company began including the Safe-T-Shift in all conversion kits in November 2003.

Enclosed in a small black box inside the truck, a computer recognizes movement and disables shifting. When the truck is stopped, the computer records no motion and allows the driver to engage or disengage the front axle or shift into high/low drive settings. The driver cannot override the system.
