Upshifting

108SD d 13.02.002
  1. Position the gear shift knob in neutral. Start the engine and bring the air system pressure up to 100 to 120 psi (689 to 827 kPa).
  2. Position the range-preselection lever down, in low range. See Fig..
  3. To start the vehicle moving, press the clutch pedal to the floor; shift into 1st gear (see Table.  ), then engage the clutch with the engine at or near idle speed. Accelerate to 80 percent of engine governed speed.

    1. Upshift progressively from 1st gear through 5th gear ( see Table. ), double-clutching between shifts, and accelerating to 80 percent of engine governed speed.
    2. When in 5th gear and ready to move to 6th gear, pull the range-preselection lever up into the high range. Double-clutch through neutral and into 6th gear, engage the clutch, and accelerate the engine.

      3. Note: If after attempting to shift into the high range the transmission remains in neutral with the shift knob in gear, the range synchronizer protection device may be activated. Move the shift knob into neutral to allow the range shift to complete, then move the shift knob back into gear.

    3. Upshift progressively through the high range gears ( see Table.), double-clutching between shifts and accelerating to 80 percent of engine governed speed.

      • High Range

      • Low Range

      • Overdrive (forward)

      • Direct Drive (rearward)
