Kenworth Truck Company now offers the Eaton Fuller Lightning 10-speed manual transmission for its T600, T800, W900, T2000, and C500 models. The Lightning transmission, rated at 1,550 and 1,650 lb. ft. of torque, is lighter than Eaton Fuller's previous Super-10 transmission and has fewer parts for easier servicing. The transmission features an aluminum clutch housing, electric splitter button control knob, and selectable Top-2 automated shifting between the top two gears. The Lightning 10-speed transmission can be spec'd with Caterpillar C-10, C-12 and C-15 and the Cummins ISX (rated at 500 horsepower or less). The transmission is approved for gross vehicle weight up to 80,000 pounds.
