Kenworth Truck Co. has announced it will offer 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, Kenworth said.

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 lbs.
