Automatics vs AMTs

Learn more about the advantages of Allison fully automatic transmissions as compared to Automated Manual Transmissions (AMTs)

Automated Is Not Automatic

Allison Automatic transmissions incorporate a hydraulic torque converter that connects the engine to the transmission via a planetary gear set. This torque converter facilitates seamless power transfer during gear changes, providing uninterrupted, continuous power shifts.

Automated Manual Transmissions (AMTs) use a standard manual gearbox

The latter often results in torque losses and interruptions during gear shifts, adversely impacting vehicle performance. Allison’s fully automatic transmissions provide superior performance, reduce maintenance and provide drivers with greater control so they can concentrate on the task at hand.

Benefits of Automatics vs AMTs

Productivity
Allison Transmission's Continuous Power Technology™ keeps the transmission working during gear shifts, keeping the vehicle in motion and the job on schedule. Vehicles equipped with an Allison Automatic transmission are up to 20% more productive than vehicles with AMTs, thanks to faster acceleration and more time spent working. AMTs require a reduction of engine throttle at each shift, causing torque interrupts. These interrupts result in more shifts and lower vehicle speeds, requiring more time to do the same job.
Driver Recruitment and Retention
The simplicity of operation and consequent reduction in driver fatigue associated with Allison Automatic transmissions have a direct positive impact on driver satisfaction and retention. The smooth shifting and less demanding driving experience enable drivers to easily maneuver the vehicle and focus on the job at hand. By contrast, AMTs require more of the driver’s attention when maneuvering due to the torque breaks, leading to increased fatigue and reduced job satisfaction.
Comfort
Allison's Continuous Power Technology™ makes sure that the engine has its full power when changing gears. This makes driving while changing gears smoother and more comfortable for both drivers and passengers. AMTs, with their inherent torque interruptions, tend to yield harsher and more frequent gear changes, and by consequence, a less comfortable ride.
Reduced Maintenance
Allison Automatics are superior because the torque converter experiences very little wear. Extended service intervals, reduced maintenance costs, and with no mechanical clutches the lifetime of the drivetrain is extended. While the manual clutch pedal is removed on an AMT, this mechanical clutch still facilitates the vehicle’s launch and will wear and eventually burn out, requiring traditional maintenance and replacement. 
Maneuverability
The torque converter in an Allison Automatic provides a continuously variable gear ratio, enhancing vehicle maneuverability. This feature allows for precise power distribution to the wheels, ensuring smooth creeping, accurate maneuvering and control on inclines. It also aids in the protection of the driveline from shocks and minimizes vehicle wear and tear. By comparison, AMTs lack a torque converter and may have difficulties in providing smooth power delivery, leading to increased wear on the clutch and potential driveline issues.
