Transmission Trends

Most automated manual transmissions go into highway tractors, but Eaton offers three vocational versions of the UltraShift Plus for on/off-road trucks such as dumps and mixers.

By Tom Berg

The swing continues toward heavy automated products, but manuals still dominate. Light and medium trucks are almost all ‘shiftless.’

Test Drive: Detroit’s Smooth Self-Shifter

This Freightliner Cascadia Evolution is equipped with a Detroit DD13 diesel and smooth DT12 automated mechanical transmission. The van shown here was empty, so we swapped it out  for a heavily loaded flatbed trailer for our evaluation.

By Tom Berg

“Proprietary” is a magic word among truck builders. It describes components of the company’s own manufacture or design that are installed on the company’s own trucks. For truck users, this can be a good thing, because they’re designed to work specifically with a company’s other components.

Save Fuel, Increase Profit, Save the Planet

Is this a case of win-win? Do the new regulations limiting greenhouse gas emissions help both the environment and truck operators’ bottom lines? So it seems.

Class 8 Update: Economics Forge Change

Western Star:The flagship from Western Star, a Daimler Trucks brand, is the 4900 with 132-inch cab and hood and long sleeper that’s built for the highway but looks good in town. It and the shorter 4800 are also equipped for vocational work with forward and setback steer axles or twin-steer configurations. Just announced is a 4800SB 8x8 whose setback, driving steer axle is paired with Meritor tri-drive rear axles.

Is trucking in for a transformation? Many believe that long-haul trucking will become less important as regional operations grow and intermodal takes over more long-haul freight, and that will change the type of heavy-duty tractor bought by many trucking companies.

Test Drive: Single-Rear-Axle Granite MHD

The single rear axle allows Class 7 ratings, but this one’s decidedly Class 8, with axles totaling 44,000 pounds in capacity. The steer axle is set forward to better handle weight of the plow mount and, when it snows, a long steel blade.

By Tom Berg

Is this single-rear-axle truck the type of medium-heavy-duty model that Mack should have brought out first? I asked that question two years ago when I saw the initial offering, the tandem-axle Granite MHD. I figured other than the tandem, it was just right for municipal fleets and others who don’t need high carrying capacity.

Transmissions: Automating for Fuel Savings

Drivers still have some control over automated manual transmissions, but the equipment will usually do a better job of improving fuel economy if it’s simply left alone.

By Jim Park

Traditional thinking on automated manual transmissions has it that AMTs are the great equalizers – bridgers of skill gaps between the best and the worst drivers in the fleet. While that’s still true, AMTs now bring even more to the fuel-economy table, offering fuel savings in their own right beyond what even the most professionally driven manual transmission could accomplish.

Test Drive: Mack's SuperEconodyne Can Lug Down Low for Fuel Savings

By Tom Berg, Senior Editor

Cruising down the Interstate, you glance at the tachometer and gasp as you see the needle hovering at under 1,200 rpm. Yet the engine isn't vibrating or straining, and the rig continues to move steadily forward
