Beyond Automatic Truck Transmissions

Up to 19% Better Fuel Economy

Meet the most fuel-efficient automatic truck transmission available today. Our Automated Gearshift (AGS) technology changes gears at optimal shift points, or allows drivers to switch over to manual mode at the push of a button. The result is up to 19% better fuel economy versus automatic transmissions, and a comfortable driving experience.

AGS Transmission Stats

Fuel-efficient Performance

This isn't your father's automatic transmission. It isn't even an automatic; it's "automated." AGS is specifically designed to work in concert with the engine, creating a symphony of fuel efficiency, lower operational costs as well as a higher driving comfort. Here's how:

  • Transmission Control Unit (TCU) – the brains behind AGS, the TCU senses truck weight, uphill or downhill grades, curves and determines precise shift points for optimum performance, fuel economy and drivetrain protection.
  • SmartShift™ – in automated mode, AGS changes gears at optimal shift points, increasing fuel efficiency with every mile

AGS: Up to 19% Better Fuel Economy

The Mercedes AGS can save you up to 19% in fuel economy compared to an automatic transmission with a torque converter. The more city, stop-and-go driving you do, the better fuel savings.

SmartShift Paddle. Select "Auto": the transmission will make all shifts automatically. Select "Man" to hold current gear or to make all shifts manually.

The standard 6-bolt PTO allows for an easy switch if you want to upgrade.

Our Mercedes-Benz designed Automatic Manual Transmission allows for more efficient shifting and greater fuel economy.

Proven Durability

Smooth shifting means longer life. Equipped with automated clutch actuation, the AGS eliminates driveline abuse, and extends the life of the transmission and the clutch.

  • Advanced Cushion-spring Clutch – AGS uses a 395xtend pushtype clutch with cushion springs that's self adjusted for longer life and reduced maintenance costs
  • Sealed Bearings and Heat-treated Gears and Shafts – designed to prevent damage, provide longer life, and decrease downtime

Lower Operational Costs

When we talk about managing costs, it's across the board. That means everything from fuel efficiency and payloads to driver training, and overall operational costs. Here's how AGS reduces long-term operational costs:

  • Easy Two-Pedal Operation – ergonomically friendly and easier to operate, lowers driver training costs, and reduces driver fatigue
  • Software-controlled Clutch Actuation – reduced wear and tear lowers your maintenance cost and increases clutch longevity
  • Automated Manual Transmission – more efficient shift points automatically lower the RPMs, increasing fuel efficiency, and minimizing operational cost
  • PTO Port Design – a standard SAE 6-bolt port on the right side ensures body builders won't need a special PTO, reducing installation costs
  • Aluminum Alloy Housing – its lighter weight, and quickly dissipates heat allowing for heavier payloads, longer life, and less maintenance

Proven Performance

Detroit Diesel has over 5 million commercial vehicle transmissions on the road today. Through our partnership with Daimler Trucks, the design of your transmission has been proven over roads in nearly every corner of the globe.
