Obdstar TCM-020 GM 6T70 6T75 6T80 Cable

The OBDSTAR TCM-020 is a dedicated diagnostic and cloning cable designed specifically for General Motors (GM) 6T70, 6T75, and 6T80 6-speed automatic transmissions. These gearboxes are widely used across GM platforms, including Buick, Chevrolet, Cadillac, and GMC, as well as select Ford and Mazda models. This cable eliminates the risky and tedious process of manually bridging pins with probe jumpers during bench operations by safely mapping the vehicle-specific transmission connection directly to a standard DB15 terminal.
