• Complete integration

    Part of our legendary integrated powertrain, mDRIVE™ HD works seamlessly with Mack engines and axles for better efficiency, more uptime and lower costs.

  • Increased driver productivity

    mDRIVE™ HD is automated, and that means less physical stress on drivers. So they can finish the job strong and stay focused.

  • Lighter than the rest

    Even though it’s built strong, mDRIVE™ HD is hundreds of pounds lighter than the competitors, so you can ditch dead weight and increase your payload.

    • AVO-BAS

      Basic Shift

      Standard gear shift strategy. Tuned for maximum fuel economy.

    • AVO-COMF

      Easy Shift

      A feature package targeting livestock haul and recreational vehicle applications and similar applications where load shifting must be minimized. It revises the AMT’s shift strategy to provide smoother launches, less aggressive shifting and more gentle driving.

    • AVO-ENH

      Enhanced "Bad Roads" Shifting

      Targeting vocational vehicles such as construction and heavy construction. Includes the Performance Mode for best performance and driveability in exchange for fuel economy. Kick-down pedal for best acceleration and performance. Premium gear lever with “Perf” button and gear selection buttons. Performance mode maximizes gradeability and improves starting and shifting in rough or hilly terrain.

    • AVO-HD

      Heavy Duty Shifting

      A more aggressive shift strategy than “Bad Roads” for heavy haul applications with more performance-oriented shift points, less skip shifting and more. Recommended to be used with Titan Heavy Haul over 80 metric tons / 176k lbs.
