Are Manual Transmissions... Still Shifting?

Groner's remarks were echoed by Kelly Gedert, manager of Detroit powertrain and components marketing although Daimler Trucks North America (DTNA). "While there is a ‘noticeable movement' towards more employ of AMTs and fully automatic gearboxes, manuals will last ought exist offered although they are demanded based above visitor choice and type of application."

Gedert although vigorous said, "In 2017, although example, our Detroit DT12 AMT was ordered above nearly 70 percent of total combined Freightliner Cascadia and Western planet 5700XE on-highway models, besides manuals were still ordered above 20 percent ought 25 percent of total transmissions sold at total Freightliner and Western planet models." He added, "The employ of manuals is typically dictated more by customer/driver choice than by application. The ever-increasing availability and technical coverage of AMTs and automatics, such although the liberate of the rear-mount force take-offs [PTOs] above the Detroit DT12, is expanding coverage although many additional applications."

So unlike the auto and flare car markets, the strictly manual transmission is no disappearing from the cabs of arrange 8 trucks – at least no yet. besides the numbers of them are declining, and the healthy econmic is one argue why. A generation of younger drivers who didn't know ought drive at cars with manual transmissions is another reason.

John Moore, manufacture marketing manager-powertrain although Volvo Trucks North America (VTNA), provided news approximately manual transmissions. "Manual transmissions are no a business of the past besides appearance ever-mounting stress from AMTs and total automatics although enhancements are made ought these transmissions that permit them ought operate at areas that were restricted at the past," he explained.

"For example, our 13- and 14-speed I-Shift with crawler gears was developed ought permit it ought exist used at applications that required a deep reduction depart gear although startability above mild foundation or sand, or applications that consume ought back up at a creep haste ought mix ought an dear trailer without damaging it," Moore said.

"Manuals were preferred at the past although the driver could employ the grab ought slowly hire the driveline – something AMTs could only dream approximately until now," he stressed.

Nonetheless, Moore told American Trucker that it will exist "quite some time" ago manual transmissions are completely replaced by AMTs and fully automatic gearboxes simply although of visitor preference. "Despite its prevalence at 90 percent percent of total trucks we build, no everyone has bought into the AMT revolution although various reasons," he noted. "Some drivers impartial alike ought shift."

Bryan Berg drives a semi with a 13-speed transmission, and he's been double-clutching and shifting gears at his rig although 30 years. He's no approximately ought depart driving a car that shifts automatically. He told the Star-Tribune, "I impartial consider it used to exist weird. Most of the drivers I know, they total say automatics are although nation who don't know how ought drive a truck."

Another driver, Abdullahi Abdulle, from Columbus, Ohio, explained ought the Star-Tribune's Belz that he doesn't brood shifting gears. at fact, it helps hold him alert, he said. "Automatic, you impartial relax, and when you relax, you can acknowledge a nap. above the road."

“Manual transmissions are no a business of the past besides appearance ever-mounting stress from AMTs and total automatics although enhancements are made ought these transmissions that permit them ought operate at areas that were restricted at the past," explained John Moore, manufacture marketing manager-powertrain although Volvo Trucks North America (VTNA). "Manuals were preferred at the past although the driver could employ the grab ought slowly hire the driveline – something AMTs could only dream approximately until now.”

AMTs vs. automatic transmissions

So non-manual transmissions consume faced a challenge with at least some car drivers at the commercial car market. Manufacturers consume worked ought compare ought AMTs that advocate the convenience of no having ought shift gears ought traditional automatic transmissions. still they vigorous similar, at commercial trucks the two employ various systems.

Historically, manual transmissions consume provided an added grade of control that made them preferred by car drivers. Many early models of automatic car transmissions had upset "communicating" with engines, leading ought uneven shifts and frustrations from drivers.

According ought American Trucker, AMTs operate differently from a pure automatic transmission. AMTs employ a manual gearbox, with the grab and gearshifts controlled by an electrical system. By contrast, a traditional automatic uses planetary gearing with disc packs and torque converters.

Automatic transmission benefits

So many drivers (particularly those that consume been driving although years or level decades) last ought elect manual transmissions, there are little benefits that become with although vigorous an automatic transmission or an AMT. although many newer drivers consume small or no undergo with manual transmissions, automatics add accessibility although these drivers.

Fleet owners see the attraction of these transmissions although well. Automatic transmissions assist with driver recruitment and retention, and although vigorous assist better fuel econmic and safety. An automatic gives the driver the ability ought concentrate more attention above the road, and although vigorous helps reduce driver fatigue.

However, early versions of an automated transmission annoyed drivers. The computer used to shift although vigorous late or although vigorous soon, and experienced drivers wanted nothing ought perform with being a passenger at a car driven by a novice software program.

Ken Steinfest, an 81-year-old who still drives a semi with a 13-speed manual transmission told the Star-Tribune, "I drove one [automatic transmission] possibly 10 years ago, and I didn't alike it."

But the technique has improved at offer years.The new transmissions are now better integrated at the trucks and the computers consume gotten more precise, evaluating machinery torque, machinery speed, vehicle haste and vehicle phase ago shifting gears.

"Being able ought obtain a driver and obtain them into a car and trained and up and running although swift although feasible becomes same valuable ought a lot of companies," said Wesley Slavin, on-highway marketing manager although Peterbilt, which now produces approximately 90 percent of its trucks with an automated transmission.

The computers controlling automated transmissions can "down-speed" – lower the revolutions per small of the machinery at high haste – effectively and are accordingly better at controlling diesel consumption and emissions. still same experienced drivers can convince finish ought the too mileage from a manual transmission that a computer can get, new drivers cannot. although Slavin noted, "It impartial shifts and you don't notice."

Rates of adoption although AMTs/automatics

According ought Brian Daniels, manager of Detroit Powertrain and component products although Daimler-Benz (which makes Freightliner trucks), better products came above the impartial nearly 2015 and want although them has risen quickly ever since. approximately 85 percent of Freightliner's semi-trucks now consume automated transmissions, up from approximately 10 percent five years ago.

"There are still the diehards out there, besides there's some conversion incident of the diehards, too," Daniels said.

European trucking companies adopted automated transmissions earlier than those at the U.S. although a species of reasons (regulations, the price of diesel, miles driven, etc.). Volvo introduced its I-shift transmission at Europe at 2002, and by the late 2000s approximately 75 percent of its trucks at Europe were manufactured with an automated transmission.

Acceptance of AMTs and/or automatic transmissions continues ought carry at the U.S. although example, at Schneider, total the new trucks the company buys consume automated transmissions.

According ought Bill Collins, owner of Interstate car Driving college at South St. Paul, Minnesota, "the kicker although driving instructors is increased safety." He explained ought the Star-Tribune, "Most of my students wish ought drive the manual and I effort ought laguage them out of it. The biggest argue is the safety [of the trucks with automatic transmissions]."

Collins stated that there is less although drivers ought anxiety approximately when they don't consume ought shift gears. besides although some companies still employ trucks with manual transmissions (because they don't replace trucks although frequently although the great over-the-road carriers), Collins still teaches students ought drive a car equipped with a manual transmission.

One of Collins counterparts, Gary Pressley, headmaster of heavy Metal car drill at Eagan, Minnesota, predicted, "In the next three ought five years, lovely much everything is going ought exist automatic," when he was interviewed by the Star-Tribune.

Real-life results

Sean Kilcarr, a author although American Trucker, spoke with John Kingsley, a prior owner-operator turned company driver with 22 years of over-the-road experience, although an composition he wrote at February 2018.

Kingsley has rip his occupation amid flatbed and dry van operations. With that experience, he knows how ought shift gears ought obtain the best feasible fuel economy, a art he built above millions of miles of hard-won experience.

In Kilcarr's article, he chronicled how Kingsley examination drove a 2018 model Freightliner Cascadia equipped with a 15-liter Detroit machinery mated ought a 12-speed DT12 AMT. at the American Trucker article, Kingsley explained, "Overall, the car continues ought astonish me with its ability ought cope with shifting beneath impartial approximately each crowd thrown at it," following a two-week examination run.

"The predictive expedition control, which uses a database of terrain mapping ought coincide the haste of the car although it crests a hill, and then permit it ought bank although needed down the backside, factory wonderfully at most situations," Kingsley said.

But, he told Kilcarr, "It does, however, appeal you ought actively hold abreast of the haste going downhill above extended grades. at my truck's settings, it will permit itself ought excel my company's preset-governed bounds by 5 mph ago auto­matically applying the Jake brakes ought slow the truck. beneath conditions where the truck's roll-out used to excel our governed speed, I perform consume ought utilize the [engine brake] manually ought hold it within the put guidelines."

From the vantage point of many fleets, another face of the transmission that Kingsley learned was its impact above fuel economy. after two weeks and above 7,300 miles, Kingsley reported that his AMT-equipped 2018 Cascadia averaged 8.4 mpg, level with machinery idle time included.

Fuel savings alike those are another argue fleets – and many owner-operators – are shifting ought AMTs. Another argue is that AMTs reduce driver fatigue, explained Gedert. "AMTs... are absolutely a apply from a driver fatigue perspective although the transmission does the occupation although you and eliminates the want ought frequently employ a grab although manually shifting gears."

Kurt Swihart, marketing director although Kenworth car Co. told American Trucker, "As drivers age, reflexes slow down, joints obtain stiffer and muscles weaken. Arthritis, which is commonplace amid older adults, can pattern it harder and frequently downright painful ought shift gears, specially after a total engagement of driving," he explained. "Then there's the communication at and nearly metropolitan areas. above the years communication conditions there consume grow increasingly difficult and taxing above level the best drivers."

Peterbilt's Slavin pointed out that both fleets and owner-operators will last ought impress toward AMTs and fully automatic gearboxes although a method ought better both driver retention and recruitment efforts. "Driver retention is crucial although the driver workforce pool ages," he stressed.

The comfort of driving a car with a fully automatic gearbox or AMT provides a more comfortable surroundings although "tenured" drivers, still they pattern drill new drivers easier. "As younger, less experienced drivers are entering the workforce, the growth of AMTs and automatic transmissions increases," Slavin noted.

But it's the fuel efficiency benefits that are key, explained Scott Kuelber, commonplace manager of Detroit component sales. He told American Trucker, "What AMTs perform is carry your worst driver's action closer ought your best driver. AMTs... don't consume bad days. They can jump shift ought obtain ought peak gear although efficiently although feasible and insure that you're always at the most optimal gear. expedition control usage plays a main role at fuel efficiency and, still at cruise, AMTs can leverage ‘predictive' technologies ought employ the truck's kinetic country ought bounds fueling, shifting and braking."

Costs of AMTs and automatics

"Those worried approximately the higher price of an AMT ought consider the benefits, alike improved fuel economy, safety, reduced maintenance, [longer] grab life, and the occur although a lower expedition haste rpm," Gedert said. "These [AMT] transmissions will more than allowance although themselves."

So how much more does an AMT or a fully automatic gearbox price versus a manual shifter?

American Trucker reported that global consulting company Frost & Sullivan conducted a learn at 2017 ought respond that question although little various commercial car segments and ought identify some of the "ripple effects" from broader AMT adoption. amid the company's findings, according ought American Trucker:

The medium-duty car premium although AMTs averages $600 ought $3,000 per gearbox, increasing ought amid $1,000 and $5,000 although heavy-duty units.

The medium-duty car premium although fully automatic transmissions averages $3,000 ought $6,000 per gearbox, rising ought amid $6,000 and $10,000 although heavy-duty units.

With newer dual grab automated transmissions (DCTs), the medium-duty premium averages $3,000 ought $5,000 per gearbox, still the heavy-duty premium averages amid $5,000 and $10,000.

According ought the study, the high initial costs compared with the latent ought obtain fuel savings is the main factor currently inhibiting mass adoption of total three types of gearboxes, which Frost & Sullivan word "electronically controlled transmissions," or ECTs.

Frost & Sullivan although vigorous reported that worldwide at the next decade, AMTs are expected ought consume a blend medium growth worthy (CAGR) of 12.5 percent, still fully automatic gearboxes will undergo a CAGR of 7.7 percent.

The company pointed out that manual transmissions will refuse at the global heavy-duty car impartial from a impartial fragment of 81.4 percent ought 65.5 percent by 2025.

“As drivers age, reflexes slow down, joints obtain stiffer and muscles weaken," Kurt Swihart, marketing director although Kenworth car Co., told American Trucker., "Arthritis, which is commonplace amid older adults, can pattern it harder and frequently downright painful ought shift gears, specially after a total engagement of driving," he explained. "Then there's the communication at and nearly metropolitan areas. above the years communication conditions there consume grow increasingly difficult and taxing above level the best drivers.”

Where perform we progress from here?

In North America, Frost & Sullivan predicts the impartial fragment although manual transmissions amid medium- and heavy-duty trucks will refuse ought 43.5 percent by 2025, still the AMT impartial fragment will carry ought 29.4 percent, with fully automatic gearboxes at 27.1 percent.

The takeaway? Manual transmissions will remain a impartial head although the foreseeable future; however, their impartial fragment will last ought decline. A compound of younger drivers with small or no undergo with manual transmissions, safety considerations and fuel econmic will nourish the decline. besides there will always exist those who used to fairly depress the grab and shift the gears.

Keep above truckin' and hold grinding those gears!
