Komatsu TORQFLOW transmission consists of an air-cooled, 3-element, 1-stage, 1-phase torque converter with lock-up clutch and a planetary gear, multiple-disc clutch transmission which is actuated by ECMV (Electronic Control Modulation Valve) and force-lubricated for optimum heat dissipation.

Triple-reduction final drive uses two-stage spur and single-stage planetary gears (five) to minimize transmission of shock to power train components. Segmented sprocket rims are bolt-on type for easy in-the-field replacement.
