Upshifting
cen dm 08.09.003
- To drive forward, make sure the vehicle is completely stopped
and the range selector lever is pushed down to put the transmission
in the low range.Push the clutch pedal to the bottom of travel so the clutch brake slows the transmission for initial gear engagement; holding the clutch pedal at the bottom of travel, shift into low.
- Slowly release the clutch pedal to begin moving the vehicle forward.
- To upshift into 1st gear, only partial depression of the clutch pedal is needed. Do not push the clutch pedal all the way to the floor and engage the clutch brake; instead, partially depress the clutch pedal, and move the shift lever into neutral.
- Release the clutch, and allow the engine to decelerate until the road speed and the engine rpm match.
- Partially depress the clutch pedal, and move the shift lever into first gear.
- Double-clutch and continue upshifting until you reach the top gear in the low range, 4th gear in 9-speed models and 5th gear in 10-speed models. See Table..
- To upshift into high range—with the transmission still in the highest low-range gear—move the range selector lever up to put the transmission into high range, then partially depress the clutch pedal and move the shift lever into neutral. As the shift lever passes through neutral, the transmission will automatically shift from low range to high range.
- Release the clutch pedal, and let the engine slow until the road speed and engine rpm match.
- Partially depress the clutch pedal, and move the shift
lever into the lowest gear in the high range, 5th gear in 9-speed
models and 6th gear in 10-speed models.
