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.

• 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.
• More than 6,000 factory-trained technicians at 2,000-plus dealer locations to support all Fuller automated products.
