5. Release the clutch pedal (manual
only), then gradually accelerate to
permit smooth starting.
6. Do not allow your vehicle to roll
(even a little) in the opposite
direction during clutch
engagement. If you need to start
up on an incline, apply your service
brakes before you release the
parking brake. Then release your
service brakes as you engage the
clutch and apply throttle.
For further instructions on operating your
transmission, see the transmission
manufacturer's Driver/Operator's
Instruction Manual.
If you want to shift directly into any gear
other than first or reverse, depress the
clutch pedal only far enough to release the
clutch. Fully depressing the pedal applies
the clutch brake and could cause gear
hang-up.
If you have a misaligned gear condition in
your vehicle's transmission and cannot
start, gradually release the clutch, allowing
the drive gear teeth to line up properly.
Then the drive gear can roll enough to
allow the teeth to line up properly and
complete the shift. The best engine
performance and maximum economy is
obtained if gears are properly selected.
This efficiency is achieved by always
selecting gears within optimum engine
rpm, which is where maximum torque and
power are obtained.
Shift carefully in a new vehicle. The
transmission may be a little stiff at first.
Avoid gear clashing, by closely following
these procedures. When you are operating
a new vehicle or one that has been
exposed to cold weather, you want the
transmission lubricant (fluid) to circulate
and coat the contacting surfaces of the
gears. Metal contacting metal in moving
parts may seriously damage your
transmission, do not drive in one gear for
long periods of time until the transmission
lubricant has a chance to coat all
contacting surfaces.
• Always select a starting gear that
will provide sufficient gear
reduction for the load and terrain.
• Never downshift when the vehicle
is moving too fast.
• Never slam or jerk the shift lever to
complete gear engagement.
• Never coast with the transmission
in neutral and the clutch
disengaged.
How to Use the Hyrdaulic Clutch
Certain vehicles have a hydraulic clutch to
shift a manual transmission.
CAUTION
Be careful not to apply the clutch
brake while the vehicle is moving. The
purpose of the clutch brake is to stop
the transmission so that you can shift
into a starting gear without grinding
gears. Applying the clutch brake when
the vehicle is moving causes a braking
effect on the drivetrain and shortens
the service life of the clutch brake.
CAUTION
Do not push the clutch pedal com-
pletely to the floor when shifting while
the vehicle is in motion. using the
clutch brake while shifting a vehicle in
motion will damage the clutch brake. A
non functioning clutch brake will make
shifting very difficult when the vehicle
is stationary.
1. Depress the clutch pedal past the
first 1/2 inch (13 mm) for
