Manual transmission twilight? After decades of dominance, they could be relegated to special status soon

Mastering an unsynchronized heavy-duty manual transmission is as much an art as a science. Old-school drivers say they simply don’t feel in complete control of a truck unless it has a manual gearbox.

Even the most ardent automated manual transmission experts admit that on a good day, a highly skilled driver with a manual transmission is equal to the best computer-controlled transmissions in the world in terms of shifting efficiency and fuel economy.

Yet, time appears to be catching up to the manual transmission. Spurred by the pressure to maximize fuel economy and safety and to integrate new drivers into fleet operations quickly and seamlessly, more carriers are spec’ing new truck purchases with automated-manual gearboxes.

OEMs, including Volvo and Freightliner, report steady and impressive take rates on AMTs – now routinely spec’d on more than half the new vehicles that roll off their factory floors.

From a high-level view, the industry trend toward AMTs seems irreversible. But reports of the manual transmission’s demise may be premature.

David Johnson, president and chief instructor at Theodore, Ala.-based Premier Driving Academy, still believes in training students on manuals because, in his opinion, it gives them a better overall feel for the vehicle. Also, he thinks it is vital for drivers to understand the mechanics and physics of up- and down-shifting.
