  3. 3rd Gear (1.269): Optimal for passing and hill climbing
  4. 4th Gear (0.966): Direct drive for efficient cruising
  5. 5th Gear (0.742): Overdrive for fuel economy at highway speeds
  6. Reverse (3.000): Adequate power for backing maneuvers

Performance Data: 0-60 mph in approximately 7.5 seconds with proper shifting technique.

Operation and Shifting Techniques

Proper shifting technique ensures smooth operation and extends transmission life.

  1. Starting: Depress clutch fully, shift to 1st gear, release clutch smoothly while applying throttle
  2. Upshifting: Lift throttle, depress clutch, shift to next gear, release clutch smoothly
  3. Downshifting: Depress clutch, shift to lower gear, blip throttle to match engine speed
  4. Reverse Engagement: Come to complete stop, lift ring under shift knob, shift left and up
  5. Skip Shifting: 1st to 3rd or 2nd to 4th possible for fuel economy

WARNING! Do not rest hand on shift lever while driving; avoid forcing gears.
