Eaton Cummins Automated Transmission Technologies has added a downsped overdrive model to its range of SmartAdvantage Powertrains.
The 1,550/1,850 lb.-ft. torque rating is compatible with rear axle ratings down to 2.47:1, enabling engine cruise speeds as low as 1,075rpm, even lower than some direct-drive transmissions, the company says. Now available through North American OEMs, the FAOM-18910S-EC3 enables more options for gradeability and improved downspeeding.
The product, which combines the X15 engine and Fuller Advantage Series automated 10-speed transmissions, offers customers the choice of small-step overdrive or direct-drive gearing. Fleets running 2010 model year trucks can expect to see 20 percent better fuel economy with the current X15 SmartAdvantage Powertrain versus the 2010 ISX15 powertrain, Eaton says.
