approximately 5 1/2 in (139.7 mm)
of total pedal travel.
2. Depress the clutch pedal another
1/2 in (13 mm) to engage the clutch
brake.
The clutch brake is used for stopping
transmission gears, allowing you to easily
shift into first gear or reverse without
grinding gears. The clutch brake is not
necessary when shifting into other gears
while in motion.
If the clutch pedal is pressed completely to
the floor and the transmission is not
shifting, then it is time to have the clutch
adjusted or serviced.
If the transmission has a butt-tooth
condition and you cannot engage a gear,
gradually release the clutch. Then the drive
gear can roll enough to allow the teeth to
line up properly and complete the shift.
The clutch is not a footrest. Do not drive
with your foot resting on the clutch pedal. It
will allow your clutch to slip, causing
excessive heat and wear, damage could
result.
When you must idle your engine for any
period of time, shift your transmission to
neutral and disengage the clutch (take your
foot OFF of the pedal). This helps prevent
unnecessary wear to your clutch release
bearing, and it is less tiring for you, too.
• Always use the clutch when
making upshifts or downshifts.
• Never coast with the transmission
in neutral and the clutch
disengaged.
• To provide smooth gear
engagements while shifting, use
proper coordination between shift
lever and clutch.
How to Shift using Double Clutch
Method
Whether you are upshifting or down
shifting, it is best to double clutch. Double
clutching is easier on the transmission and
on the engine, helping your vehicle match
engine speed with driveline speed and
achieving clash-free shifts.
To 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 mainshaft gears, allowing
you to match the rpm of the
mainshaft gears to those of the
output shaft.
a. a. Upshifts: let the engine and
gears slow down to the rpm
required for the next gear.
b. b. 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.
Automatic and Automated
Transmissions
An automatic or automated transmission
makes shifting much easier. It remains
important to completely understand how to
operate the transmission to optimize its
efficiency. Please read the manual for your
automatic or automated transmission
included with your vehicle.
For automated transmissions, there is no
"park" position. So you will need to apply
the parking brake before leaving the cab.
