PURPOSE: An automotive harness module of an auto transmission is provided to simplify connection structure with a transmission control unit, by minimizing the number of communication lines extended to the transmission control unit. CONSTITUTION: A power line(13) supplies a power source to a plurality of solenoid valves(5, 7) and a plurality of sensors(9, 11). A signal branching device(23) transfers a control command to the plurality of solenoids. The signal branching device transfers every kind of sensing signal to a transmission control unit. External communication lines(15, 17, 19) connect the transmission control unit and the signal branching device. Internal communication lines(16, 18) connect the signal branching device and the plurality of solenoid valves and the plurality of sensors.
