A Brief History of the Automated Manual Transmission (AMT) in Heavy Trucks

Automated Manual Transmissions (AMTs) are hybrid gearboxes that combine the internal mechanism of a traditional manual transmission with electronic controls to automate clutch engagement and gear shifting. In essence, an AMT uses a standard manual gearbox (with its multiple gear sets and clutches) but relieves the driver of having to operate the clutch pedal or shift lever. Instead, computer-controlled actuators handle all clutch and shift…
