Downshifting

108SD d 13.02.003

Important: Never use the clutch brake when downshifting, or as a brake to slow the vehicle.

  1. Downshift progressively through each of the high range gears, double-clutching between shifts.
  2. When in 5th gear and ready to move to 4th gear, push the range-preselection lever down into the low range. Double-clutch through neutral and into 4th 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. Downshift progressively through the low range gears, double-clutching between shifts, as conditions require.
