UltraShift PLUS MXP automated manual transmission

The UltraShift PLUS MXP 18-speed automated manual transmission is the workhorse of the transmission lineup. Need a transmission capable of hauling 168,000 pounds (76.203 kg) on steep grades? Look no further than here. With world-class startability and ratio coverage, and built upon the robust Eaton Fuller 18-speed manual transmission design, these automated manual transmissions are capable of handling high torque and high GVWs, making them popular in some of the most rigorous vocations you’ll find - logging, oil field and other heavy-haul applications. In fact, the 18-speed UltraShift PLUS MXP has no gross vehicle weight limitation. Fleet managers and drivers alike will appreciate the improved safety and greater fleet-wide fuel efficiency these automated transmissions deliver compared to their manual counterparts.

Key features include:

  • GearLogic™ technology for improved performance, fuel efficiency and driver confidence
  • Compatible with two-speed axles for enhanced gear reduction to maximize on-/off-road capabilities
  • Compatible with split-shaft power take-off (PTO) - allows for transmission gear selection and clutch control from a panel outside of the vehicle's cab along with the remote throttle eliminating the need for operators to enter and exit the cab to change transmission gears

Performance You Can Count On

Vehicle control is vital on job sites. That’s why we engineer advanced features such as GearLogic™ technology, which improves low-speed performance, into our products. When it comes to grades, UltraShift PLUS transmissions offer superior performance compared to torque converter automatics. The Aggressive Performance calibration also improves acceleration through enhanced shift strategies. Enhanced split-shaft power take-off (PTO) capabilities allow the operator to control the throttle and transmission gear selection outside the vehicle’s cab for improved efficiency and safety.

Designed for Your Bottom Line

UltraShift PLUS transmissions are designed for optimal fuel efficiency, and less wear and tear on drivetrain components for reduced maintenance costs. Compared to a torque converter automatic, an UltraShift PLUS will cost you about 50% less. It will also double the length of lubricant change intervals and use 50% less fluid. Service can be performed at your local dealer to get your vehicle back on the job faster maximizing your uptime -- no need for a two-step repair process.
