Shifting The Transmission
You will find a shift pattern either on a decal in your cab or
on a medallion in the shift knob. Check to be sure you
know the correct sequence for your particular transmis-
sion. Refer to the transmission manual included with your
vehicle for complete instructions in the operation of your
transmission.
Shifting Gears in a New Vehicle
Shift carefully in a new vehicle. The transmission may be
a little stiff at first. So be careful to avoid gear clashing.
When you are operating a new vehicle or one that has
been exposed to cold weather, you want the transmission
lubricant to circulate and coat the contacting surfaces of
the gears. Metal contacting metal in moving parts may
seriously damage your transmission. So don’t drive in one
gear for long until the transmission lubricant has had a
chance to coat those contacting surfaces.
Operating the Clutch
“Riding” the Clutch
The clutch pedal is not a footrest. Driving with your foot on
the clutch pedal will allow your clutch to slip, causing
excessive heat and wear. You can damage your vehicle
this way.
Clutch Travel
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 engine, clutch,
other transmission components, and may
cause damage.
To put your vehicle into motion, push down on the clutch
pedal until the clutch brake makes contact. This contact
will occur at about 1/2 inch to 1 inch from the end of pedal
stroke. Select a gear low enough to let your vehicle start
forward with the throttle at idle until the clutch is fully
engaged.
