Upshifting

cen dm 08.10.003
  1. 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.
  2. Slowly release the clutch pedal to begin moving the vehicle forward.
  3. 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.
  4. Release the clutch pedal, and allow the engine to decelerate until the road speed and the engine rpm match.
  5. Partially depress the clutch pedal, and move the shift lever into 1st gear.
  6. Double-clutch to continue upshifting until in fourth gear. See Table..

    1. To upshift into high range—with the transmission still in 4th gear—push the range selection 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.
    2. Release the clutch pedal, and let the engine slow until the road speed and engine rpm match.
    3. Partially disengage the clutch, and move the shift lever into 5th gear.
    4. To upshift from 5th gear into 5th overdrive, flip the splitter control button up to the overdrive position; then, immediately release the accelerator, and press and release the clutch pedal. It is not necessary to move the shift lever when shifting from direct to overdrive; the transmission will shift when synchronization with the engine's speed is reached. Accelerate the engine only after the transmission has shifted.
    5. To shift from 5th overdrive to 6th direct, partially disengage the clutch, shift into 6th—but before engaging the clutch—flip the splitter control button down into the direct drive position; then engage the clutch, and accelerate the engine.
      Do not move the control button while the shift lever is in neutral.
    6. Shift upward through each of the high range gears, alternating the procedures in steps 10 and 11, above.
