Transmissions
If your truck has an automatic transmis-
sion, go to page 62
.
If your truck has an automated manual
transmission, such as the Eaton® Auto-
shift™, go to page 63
.
Your transmission has six forward gears
with full synchromesh engagement,
and one reverse gear. You will find a
shift pattern diagram on the gearshift
knob. Make sure you follow the correct
sequence for shifting your transmission.
Transmission Warm–Up
In cold weather [below 32°F (0°C)], you
may find shifting sluggish when you first
start up. Transmission warm-up is
especially important at this time, but it is
always a good idea to warm your trans-
mission oil before starting out on the
road.
To warm the transmission lubricating oil
during engine warm-up:
1. Put the transmission in Neutral.
2. Release the clutch pedal and let
the transmission operate in Neutral
for three to five minutes prior to
shifting into either a forward or
reverse range.
Putting the Vehicle in Motion
WARNING! Never drive your
vehicle with the parking
brake applied. Always
release the parking brakes
prior to moving the vehicle.
Failure to disengage the
parking brakes prior to mov-
ing your vehicle could result
in excessive heat build-up in
the brake system, resulting
in a fire.
NOTE: Today’s diesel elec-
tronic engines have significant
torque and startability power at
low RPM. Combinations of
engine speed and available
torque may over-power the
vehicle’s parking brakes.
