Automated Manual Transmissions

When your fleet demands maximum efficiency and performance, you need a heavy-duty transmission built for the long haul. Automated Manual Transmissions (AMTs) combine the rugged durability and fuel efficiency of a traditional manual with the seamless, automated shifting of an automatic, making them an essential choice for modern heavy-duty commercial trucks.

At Allied Powertrain Group, we provide access to high-performance replacement remanufactured Automated Manual Transmissions for heavy-duty applications. Whether you operate regional haulers, long-distance freight fleets, construction rigs, or vocational heavy-duty vehicles, our team can help you identify the exact AMT unit to keep your trucks moving and minimize costly downtime.

Automated Manual Transmissions: Built for Performance and Efficiency

Automated Manual Transmissions (AMTs) combine the mechanical strength and gear efficiency of a standard manual transmission with computer-controlled clutch operation and pneumatic shifting. Designed to optimize fuel consumption, reduce component wear, and lower driver fatigue, AMTs are the industry standard for modern heavy-duty commercial fleets.

On Highway & Long-Haul Freight

Long-haul fleets rely on 12-speed AMTs—such as the Detroit DT12, Volvo I-Shift, Mack mDRIVE, and Eaton Cummins Endurant—for interstate routes. Predictive shift logic optimizes engine RPMs to maximize fuel economy over thousands of miles.

Regional Freight & Day-Cabs

For trucks handling local hub-and-spoke distribution, AMTs eliminate manual clutch depression, reducing driver fatigue in heavy traffic.

Construction & Concrete Mixers

Heavy dump trucks and cement mixers leverage severe-duty AMT variants equipped with deep crawler ratios for controlled, low-speed maneuvering on unstable terrain under heavy loads.

Logging, Mining, & Heavy Haul

Modern AMTs electronically manage clutch engagement during extreme torque demands, preventing torque disruption and protecting the drivetrain from shock loads.

Refuse & Waste Management

Stop-and-go collection routes benefit from low-speed creep modes and automatic neutral engagement, improving safety and drivetrain longevity.

Snowplows & Highway Maintenance

AMTs allow municipal operators to keep both hands on the wheel while actively managing plows or spreaders.
