The UltraShift LEP transmission uses optimized shift calibrations tailored to each engine’s unique fuel map, keeping RPM's low while maintaining driveability in virtually any terrain.
The shift calibration software is optimized and unique for each individual heavy-duty commercial engine.
Computer-controlled shifting provides a balance between efficiency and driveability for:
Low-speed maneuverability
Excellent launch quality with gathered ratios in hi-range for optimum control of engine torque and speed.
Automation provides the driver with greater comfort, increasing satisfaction. Fully automatic operation (no clutch pedal) eliminates manual shifting for increased safety.
Specifically suited for on-highway applications offering torque capacity up to 1650 lb-ft, and up to 1,750 lb-ft in top two gears with “M” multitorque option (in the top four gears with a Caterpillar C13 & C15).
Designed for linehaul operations up to 80,000 lb. [36,287 kg] GCW at cruise speeds up to 65 mph [105 kph].
Driver is still in control
"Manual" mode allows the driver to initiate and control shifts for flexibility during changing conditions or hold a gear as appropriate.
"Low" mode boosts the rpm point at which downshifts occur to maximize engine braking.
Designed and built for reliability and easy service
Electronic shift protection feature helps reduce the potential for drivetrain abuse…continuous electronic monitoring provides for quick, accurate diagnosis and repair.
Modular components allow for easy service and replacement…often without removing the transmission.
Automated clutch uses proven heavy-duty 15-1/2” two-plate design with an industry standard ceramic facing material for long service life.
