OPERATING THE 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
transmission 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
After making sure the vehicle's oil
and air pressure are correct and all
other parts and systems are in proper
working condition:
1. If your truck is equipped with a
hand throttle, disengage the hand
throttle before driving the vehicle.
2. Fully depress the clutch pedal until
the clutch brake makes contact.
The contact will occur at about 1
inch or less from the floorboard.
°
The total stroke of the clutch
pedal is about 10 inches. The
first 1½ inches is free travel.
After the free travel comes
the release stroke, which is
the part that fully releases the
clutch. The last inch engages
the clutch brake.
°
Always start out in a low gear.
Starting in a higher gear,
even with a light load, will
cause a very jumpy start and
excessive wear.
CAUTION
Always use first gear or a low speed
range to start the vehicle in motion.
The use of a higher gear or speed
range forces undue strain on the en-
gine, clutch, other transmission com-
ponents, and may cause damage.
3. Evaluate the road surface
conditions and terrain your vehicle
is on. Select a gear low enough to
let your vehicle start forward with
the throttle at idle.
4. Push the parking brake valve
handle (Yellow) against the dash
panel to release the brakes.
5. Release the clutch pedal, then
gradually accelerate to permit
smooth starting,
6. Do not allow your vehicle
to roll (even a little) in the
