Downshifting
NOTE: With the transmission in drive (D) in the
automatic mode, downshifts require no driver
interaction.
1.
With the transmission in drive in the manual
mode, request a downshift by pushing downward
on the control. If the requested gear is available,
the transmission will downshift.
NOTE: A single, momentary push downward on
the control selects the next lower gear when it is
available. Two consecutive, momentary down-
ward pushes will cause a skip shift, when the
next two lower gears are available and condi-
tions are right.
2.
To skip shift, move the control two times in less
than 1/2 second. The number of the gear en-
gaged will appear on the message display
screen.
NOTE: The Eaton Fuller AutoShift 18-speed
transmission is able to perform triple downshifts
when the next three lower gears are available
and conditions are right. To triple shift this trans-
mission, move the control three times in less
than 1/2 second.
If a requested gear is not available, an audible
warning will sound and the message display
screen will indicate that the requested gear is
not available. Unlike upshifting, an unavailable
requested downshift is stored in memory and
the shift will be made when the gear is avail-
able. The time limit for this memory is a pro-
grammable parameter.
Low Gear Operation
Use low (L) when descending steep hills and using
compression braking. Engine speed will be increased
by 200 rpms and shift points will be offset by 200
rpm. The efficiency of the exhaust brake will be maxi-
mized.
Using the Clutch
Use the clutch to start and stop the vehicle.
Operation, AutoShift (without
SmartShift)
WARNING
If the engine cranks in any gear other than neu-
tral, have the vehicle serviced immediately. If the
vehicle is started in gear it will suddenly move
forward or backward, which could result in per-
sonal injury and damage to property and the
transmission.
