match your vehicle's engine speed with
driveline speed to achieve clash-free shifts.
The manual transmission in your vehicle is
not equipped with gear synchronizers.
Whether you are upshifting or
downshifting, it is best to double clutch.
T
o double clutch:
1. Push the clutch pedal down to
disengage the clutch.
2. Move the gear shift lever to neutral.
3. Release the pedal to engage the
clutch. This lets you control the rpm
of the transmission mainshaft
gears, allowing you to match the
rpm of the mainshaft gears to those
of the output shaft.
• Upshifts: let the engine and
gears slow down to the rpm
required for the next gear.
• Downshifts: press accelerator,
increase engine and gear
speed to the rpm required in the
lower gear.
4. Now quickly press the pedal to
disengage the clutch and move the
gear shift lever to the next gear
speed position.
5. Release the pedal to engage the
clutch.
Automated Transmissions
This vehicle may have a P
ACCAR or Eaton
automated transmission. It remains
important to completely understand how to
operate the transmission to optimize its
efficiency. Please read the manual for the
automated transmission included with your
vehicle.
Not all automated transmissions have a
"park" position, so you will need to apply
the parking brake before leaving the cab.
WARNING
If your vehicle has an automated
transmission,
be aware that it can roll
backwards when stopped on a hill or
grade, or when starting from a stop on
a hill or grade. Failure to comply may
result in death, personal injury, equip-
ment or property damage. Observe the
following guidelines: (1) When stopped
on a hill or grade, press the brake ped-
al. (2) When starting from a stop on a
hill or grade, quickly remove your foot
from the brake pedal and firmly press
on the accelerator pedal.
WARNING
DO NOT leave the cab of your vehicle
without
applying the parking brake.
The truck could roll and cause an acci-
dent resulting in death or personal in-
jury. Always apply the parking brake
before you leave the cab.
Hill Hold
The hill hold feature is available as an
option with certain automated
transmissions. This feature holds the
vehicle while on a hill to allow the operator
to release the service brakes and press the
accelerator. This feature will hold the
vehicle if the vehicle is attempting to go up
a hill from a stop in either drive or reverse.
Shift Configuration
Some transmissions are equipped with
more than one shifting configuration to
match various operating conditions. Please
read the automated transmission manual
