“There’s a 30% variability from driver to driver doing the same work,” said Kris Ptasznik, Cummins’ X15 product manager.

“Driving is believing.”īecause fewer and fewer drivers know how to drive stick, it also makes it easier to recruit and see better performance. “They were not difficult to convert,” Barraclough said.

Scott Barraclough, technology product manager at Mack Trucks, said manuals are now few and far between. Likewise, Navistar International said manuals have shrunk to a few percent, while Kenworth Truck’s linehaul builds with AMTs jumped from 30% in 2013 to about 70% in 2018. The other 1% are fully automatic.Īn estimated 90% of all Volvo Trucks are being built with AMTs.
Numerous other truckmakers and suppliers made similar moves, and the Class 8 tractor was never the same again.ĭTNA said 94% of new Freightliner Cascadias are being spec’d with automated manual transmissions and 5% manual.
Daimler invested $100 million to manufacture the Detroit DT12 AMT, engineered to provide good fuel economy and a better user experience for the driver. That study predicted manual’s global share would decline to 65.5% by 2025, but the change came much sooner.īack in 2012, Martin Daum, CEO of DTNA at the time, made it his “mission” to change a market using 90% manual transmissions. They made up for that by providing better fuel economy, with up to 8% for AMTs and 3% to 5% for ATs. A 2015 Frost & Sullivan study found heavy-duty AMTs cost $1,000 to $5,000, and ATs cost $6,000 to $10,000 more than their manual counterparts. Not long ago, manual transmissions were the preferred choice based on economics: They cost less and provided good fuel economy. The modern automatic transmission is less a component on the truck than a co-pilot, using navigation, load data, and preset fleet standards to make sure the driver is comfortable and focused on the road while also ensuring smooth operation to reduce wear and achieve maximum fuel economy. Whether it’s a fully automatic transmission (AT), which uses a torque converter, or automated manual transmission (AMT), which internally operates like a manual but shifts with computer-controlled actuators, these options are easier on drivers and equipment. Manuals may be needed in certain vocational applications, but fleets are likely to order them “only if they absolutely need it,” Roger Nielsen, president and CEO of Daimler Trucks North America (DTNA), predicted. Similarly, Jason Skoog, general manager of Peterbilt Motors, suggested it is unlikely there will be many manuals a decade from now, though the manufacturer “lets customers decide what happens with our product portfolio.” He suggested it may only be “a few more years” before the only manual transmissions in trucks are generally those trying to keep it “old school.” Horton said about 94% of orders for Mack’s highway flagship Anthem model are now spec’d with the mDrive automated manual transmission, and there is a similar trendline across other models. “The age of manual transmissions … is slowly coming to a close,” said Roy Horton, director of product strategy for Mack Trucks. While it’s debatable that computers will ever autonomously operate the whole truck, no one can argue they have the gear-shifting gig well under control. Over the past decade, the trucking industry has discovered that automatic transmissions are better than humans at reliably and accurately performing precisely timed motions. The digital transformation appears close to killing the manual truck transmission.
