Manual Transmission — 6-Speed (G238)
NOTE: The parking brake should be engaged before
leaving the vehicle, especially on an incline.
1500 models are equipped with a G238 manual transmis-
sion. This transmission has a clutch interlocking ignition
system. The clutch pedal must be fully depressed to start
the vehicle.
Fully depress the clutch pedal before shifting gears. As
you release the clutch pedal, lightly depress the accelera-
tor pedal. When launching a stationary vehicle, keep the
engine speed low until the clutch is fully engaged.
For improved clutch life, all six forward gears should be
used. For steady highway driving with light acceleration,
6th gear is recommended. When shifting from 5th to 6th
gear, do not apply excessive knob load toward the
Reverse gear gate, as you may overpower the Reverse
“crash-through” load and unintentionally clash into Re-
verse gear. Also, when shifting from 6th to 5th gear,
excessive knob load toward the Reverse gear gate will
result in blocking of the shift.
You should use first gear when starting from a standing
position. Damage to the clutch can result from starting in
2nd or 3rd gear. Use each gear in numerical order – do
not skip a gear.
