related to data links, which play a key role
in AMT operation. When not functioning
properly, data links can cause undesirable
vehicle launches and shifting issues.
Having the ability to perform remote

the 12- to 18-month range, " he said.
With a pneumatically shifted AMT, techdiagnostics
on AMTs also can prove important
to a fleet.
" With an AMT, a computer is essentially
deciding when to shift gears and perform
clutch actuations, " Saholsky said. " If the
transmission system fails to perform as
expected in the field, the ability to connect,
diagnose, and repair from a remote location
can help get the vehicle back up and
running much faster. A remote diagnostics
tool such as Eaton's IntelliConnect helps
monitor system performance, recognize fault
codes, and initiate fault code action plans. "
Navistar's array of connectivity and remote
nicians should pay close attention to the air
system. To that end, waiting until the dryer
fails to replace the desiccant cartridge is
not a sound preventive strategy. For standard
delivery vehicles and double- and
triple-trailer linehaul
trucks, Saholsky

diagnostics were also baked into the T14, allowing
for predictive maintenance and over-the-air
updates to calibrate and reprogram transmission
software. To optimize uptime, machine-learning
algorithms will also steer what service facilities
in the network are stocked with critical parts
to ensure parts are always available if service
is needed.
Aside from the technology aspect, AMT maintenance
has a couple of other differences, as
Saholsky pointed out. " Heavy electrical draw can
impact battery life, which may be the case with an
electrically shifted AMT. That means fleets may
said every two years or 200,000 miles is a
good rule of thumb. On severe-duty vehicles
like dump trucks and refuse trucks,
the recommended interval is once a year,
or every 100,000 miles.
Routine maintenance like lubrication
intervals are similar between an AMT and
manual transmission. That said, AMTs require
specially formulated lubricants, such as Eaton's
PS-386 synthetic lubricant, for added wear
protection and fuel economy.
Steven Bowles, senior product specialist for
lubricants at Citgo Petroleum, said there has
been another industrywide trend developing
with AMT fluids.
