SPOTLIGHT ON DRIVETRAIN
Transmission
transition
As the industry continues down its long
path to electrification, technicians must
remain attentive and agile when servicing
today's evolving drivetrain solutions.
By Gregg Wartgow
I
t is pretty clear that the future of commercial fleets is moving
toward a day when most trucks and vans are electric. What
isn't clear is when that day will fully come. In the meantime,
technicians have to stay on top of all the tweaks and trends
with conventional transmissions that will continue to show up
in the service bay.
" Electric vehicle technology and infrastructure will need to
evolve before it can fully support medium- and heavy-duty trucks
and buses, " said Branden Harbin, executive director of global
marketing at Allison Transmission, referring to battery efficiency
and charging stations. " Therefore, conventional solutions will still
be necessary for years, if not decades, to come. "
Automated manual transmissions (AMTs) and automatics have
already gone through a fair bit of evolution, adding technological
improvements that help improve efficiency. OEMs have also been
pushing integrated powertrains, where the engine and transmission
were designed to offer more power and efficiency together.
The latest, Navistar's S13 Integrated Powertrain for International
trucks, features an S13 engine mated to the new T14 (14-speed)
