Fully press the clutch pedal before shifting gears. As you
release the clutch pedal, lightly press the accelerator
pedal.

This transmission has a “creeper” first gear which should
be used to start from a standing position when carrying
a payload or towing a trailer. Damage to the clutch can
result from starting in second or third gear with a loaded
vehicle. An unloaded vehicle may be launched in second
gear. Use each gear in numerical order – do not skip a
gear.

NOTE:

When loaded, pulling a trailer or on a grade, the

truck should always start in first gear and not skip gears.

Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for both
fuel economy and performance, it should be upshifted as
listed in recommended shift speed chart. Shift at the

vehicle speeds listed for acceleration. When heavily
loaded or pulling a trailer these recommended up-shift
speeds may not apply.

Downshifting

Moving from a high gear down to a lower gear is
recommended to preserve brakes when driving down
steep hills. In addition, downshifting at the right time
provides better acceleration when you desire to resume
speed. Downshift progressively. Do not skip gears to
avoid overspeeding the engine and clutch.
