Eaton Automated-Manual Transmission

Navistar Al's Tech Tips

Uncle Al’s UTC Tech Tip

The information in these tech tips is to help increase UTO / UTC customer satisfaction


UltraShift Plus & Smart Advantage Series

This week’s tech talk supports discussions with clients that may never have encountered a manual automated transmission.

  • The majority of current International trucks on your UTC lot have the Eaton automated-manual transmission and are either Ultrashift Plus or Smart Advantage models with N13 or ISX Cummins power. Drivers appreciate the improved safety , ease of driving and greater fuel efficiency these automated transmissions deliver compared to their manual counterparts or torque converter automatics (Allison).
  • Depending on the customer’s new truck order, the automated transmission may have been programed from the factory with option modes. The specific transmission model and options can easily be identified by entering the truck’s vin in service portal, then go to the “component” tab, open and scroll down to “transmission”. (NOTE: Factory option programming is not changeable.)
  • The Smart Advantage series offers design advantages when compared with the UltraShift Plus:
  • calibrated to maximize fuel economy
  • Improved transmission efficiency and reduced mass deliver up to 3% to 5% improved fuel economy
  • Increase in aluminum components reduce weight up to 82 lbs and holds 8 pints less fluid than UltraShift Plus

Listed below are explanations standard and optional modes for both transmissions :

Multiple Operating Modes: Standard

Automatic, Manual and Low modes offer the driver full control. In Manual mode, the driver can override computerized shifts on demand. Using Low mode can help maximize engine braking and reduce wear on brakes.

Automatic Grade Braking : Standard

Downshifts the transmission to help slow the truck on long, steep descents and increases brake pad life.

Hill Start Aid: Standard

Prevents unintended roll back or roll forward. When the grade exceeds one percent, foundation brakes hold the truck for a controlled launch. It works when pointing uphill in drive or facing downhill in reverse

Blended PedalOptional

Drivers can use the throttle to feather the clutch for seamless low-speed control

Urge to Move : Optional

Drivers simply release the brake pedal to automatically inch forward, similar to the feel of a passenger car.

Creep Mode: Optional

Enables the driver to “creep” at low speeds, and offers ultimate control for curbing, spreading and paving

Skip Shifting : Standard

Automatically skips unnecessary gears to increase shifting efficiency. Helps increase acceleration to achieve cruising speed quickly and smoothly.

Engine Overspeed ProtectionStandard

The transmission system upshifts, if necessary, to prevent engine overspeed in Drive, Manual and Low modes

Smart Gear SelectionStandard

The appropriate starting gear is selected and makes shift decisions based on grade, vehicle weight, engine torque and throttle position—skip shifting when appropriate, making the most efficient shift changes.

Auto Neutral : Standard

Automatically switches the transmission into neutral, once the parking brake is engaged, to prevent potential movement.

Self-Adjusting Ceramic ClutchStandard

Dual-plate ceramic clutch for improved durability in high GVW applications.

Electronic Clutch Actuator: Standard

Enhances maneuverability at lower and reverse speeds, and makes backing up even easier.
