Auxiliary Transmission
(option)
This transmission can be equipped and
configured to utilize an auxiliary
transmission. The auxiliary transmission is
activated using the auxiliary transmission
switch (see
Auxiliary Transmission Switch
(option) on page 31). See the auxiliary
transmission operator's manual for
operation of the auxiliary transmission.
Auto-neutral
The Auto-neutral feature will automatically
shift the transmission into Neutral if it is left
in a forward or reverse mode (such as Low,
Drive, or Reverse) and the parking brake is
set. The transmission gear display shows
AN when Auto-neutral is activated.
NOTE
If Auto-neutral has been activated, the
transmission will not shift into Drive (
D )
or Reverse ( R ) until the shifter is first
moved to Neutral ( N ) before selecting
another transmission mode.
Clutch Abuse Protection
The clutch can overheat with improper use.
If clutch temperature is elevated or
overheating (see
Clutch Temperature
Gauge on page 24), Clutch Abuse
Protection will turn on, producing an
audible tone and may indicate
CA in the
transmission gear display (option).
When active, Clutch Abuse Protection
• Limits launch gears to 1
st
and R1
• Disables Urge to Move
• Disables Creep Mode
When Clutch Abuse Protection is active,
full clutch actuation must be completed
quickly or the clutch will automatically close
when the accelerator pedal is pressed and
open when it is not. If clutch abuse
continues, Clutch Abuse Protection will
prevent clutch engagement and
temporarily remove control of the
accelerator pedal, allowing the clutch to
cool down.
Coast Mode
Coast Mode shifts the transmission into
neutral when coasting to a stop, providing
a smooth stopping experience.
When slowing down on level terrain, the
transmission will downshift, remaining in
gear until it reaches the coast down gear. If
the vehicle continues to slow (and the
accelerator pedal is not applied), the
transmission assumes the operator intends
to stop, and shifts into neutral.
Coast Down Gear:

th
If the accelerator pedal is applied while in
Coast Down mode, the transmission will
shift into a gear appropriate for the current
vehicle operating conditions.
NOTE
The Coast Down Gear can be
changed at your PACCAR Powertrain
distributor.
