STARTING AND DRIVING
ALLISON TRANSMISSION
to find contact and location information
for Allison Transmission distributors and
dealers.
Overview
Smooth automatic upshifts and
downshifts, without interruption of
power to the wheels, occur in your
Allison automatic transmission based on
engine rpm, throttle position, vehicle
load, road speed, and driver or feature
request, such as manually preselecting
ranges.
Allison automatic transmissions, along
with a vehicle specification appropriate
for the particular duty cycle, can provide
superior fuel efficiency and optimum fuel
economy. On trucks with a manual or
automated manual transmission, the
power interrupts that occur during shifts
reduce the engine’s inertia energy,
resulting in lower average wheel
horsepower. Because the engine is not
working efficiently, it cannot run at full
load. With an Allison automatic
transmission, there is no power interrupt
during shift changes. The inertia energy
built up by the engine is maintained,
equating to higher wheel horsepower. As
a result, not as much engine horsepower
is needed to get the job done. Allison
automatic transmissions provide
smooth, seamless shifts at all points of
the power curve
;
there is no jarring
power interrupts to jostle the truck,
driver or damage valuable cargo. Allison
automatic transmission equipped trucks
are more nimble in traffic and easier to
maneuver in congested loading zones,
narrow alleys and around tight corners.
You will have fewer freight claims and
reduced cycle times, no matter how
difficult the route.
