Why Automatic Trucks Are Replacing Manual Transmissions

Did you know that nearly 85% of new Freightliner trucks now leave the factory with automated transmissions? The days of double-clutching, grinding gears, and clutch replacements are quickly disappearing from modern trucking fleets.

The trucking industry is evolving, and automated manual transmissions (AMTs) are leading the way. Major carriers such as Schneider National, Swift Transportation, May Trucking, Western Express, CR England, and CRST have adopted automated transmissions across most—or all—of their fleets. Schneider National, for example, now operates a fleet that is 100% automated, allowing drivers to focus on the road instead of constantly shifting gears.

Why the change? Automated transmissions improve fuel economy, driver comfort, and vehicle longevity. By removing the clutch pedal and managing gear shifts electronically, AMTs reduce driver fatigue and eliminate costly clutch wear. Fleets also report improved safety because drivers can focus more on traffic conditions and less on managing gears.

What Is an Automated Manual Transmission?

An automated manual transmission is essentially a computer-controlled manual transmission. Instead of the driver operating a clutch pedal and gear shifter, the truck uses hydraulics, sensors, and onboard computers to shift gears automatically.

Drivers operate the truck using two pedals—accelerator and brake—just like a modern car. The transmission selects the correct gear based on speed, engine load, and driving conditions. This technology allows for smoother shifting while maintaining the durability of a traditional manual gearbox.

The “Manual vs. Automatic” Debate

If you talk to drivers who have been in the industry for decades, you will often hear the same advice:

“You need to learn manual transmissions.”

Sometimes this advice comes from a well-meaning relative—what we jokingly call “Uncle Manuel”—who insists that real truck drivers shift gears.

But the truth is that the trucking industry has changed dramatically. The majority of modern fleets now purchase automated trucks exclusively, and many drivers will go their entire careers without touching a manual transmission. Learning manual shifting was once essential because that was the technology available. Today, however, automated transmissions are simply the standard equipment on modern trucks.

Mechanical Skill vs Professional Driving

One reason the manual transmission debate continues is that mechanical difficulty is often confused with professional skill. In the past, learning to operate a manual transmission was necessary because that was the only technology available in commercial trucks.

But shifting gears does not define what makes a driver professional. Professional truck driving is about safety, judgment, situational awareness, and vehicle control, not the mechanical difficulty of the equipment being operated. Automated transmissions simply remove a mechanical task so drivers can focus more on these critical aspects of operating a commercial vehicle safely.

Consider the aviation industry. Modern airline pilots rely heavily on automated flight systems that handle many tasks pilots once performed manually. No one argues that pilots are less professional because they no longer manually control every aspect of flight. Automation simply allows them to focus on the most important responsibilities: safety, navigation, and decision-making. The same evolution is happening in trucking.

If operating a manual transmission truly made someone a better or more professional driver, the market would reflect it. Insurance companies would offer lower premiums for fleets operating manual trucks, and companies would pay drivers more for operating manual transmissions. In reality, neither of those things happen. Insurance providers and fleet operators care about safety records, crash rates, and operational efficiency, and modern automated transmissions have proven to perform well in all of these areas.

In other words, the difficulty of older equipment should not be mistaken for the standard of professionalism in modern trucking. The industry has moved forward, and automated transmissions have become the new standard across most commercial fleets.

The Restricted Class A License

Drivers who take their CDL road test in an automated transmission truck receive a restricted Class A license, meaning they are limited to operating trucks with automated transmissions.

For most drivers, this restriction does not create employment barriers. The majority of major carriers—and many regional and local fleets—now operate automated trucks. Unless a specific employer specifically requires experience with manual transmissions, an automated CDL is more than sufficient for most trucking jobs in today’s industry.

The industry’s evolving view of manual transmissions is also becoming evident at the regulatory level. At recent industry conferences such as those hosted by the Commercial Vehicle Training Association (CVTA), discussions have taken place about potentially treating manual transmission operation more like a specialized endorsement rather than a restriction. While no official rule changes have been implemented, the conversation itself reflects how the industry increasingly views manual transmissions as legacy equipment rather than the standard.
