   Remove transmission-hydraulic oil filter (A) with the help of oil filter wrench.

6. Apply a film of oil to new filter O-ring and install new transmission-hydraulic oil filter (A). Hand tighten plus 1/2 turn with the oil filter wrench.

7. Open transmission oil filler cap (D) and fill system with transmission-hydraulic oil. See Fuels, Lubricants and Coolant section.

8. Check oil level on dipstick (C) after filling oil. Oil level should be up to full level mark (E) as shown. Add transmission-hydraulic oil if necessary.

   IMPORTANT: Avoid damage! DO NOT overfill oil in transmission. Oil expands during operation and could overflow.

   NOTE: Transmission oil can be changed every 1200 hours or 3 years if the following requirements are met:

   • Use John Deere Hy-Gard™ or Lo-Vis Hy-Gard oil.
   • Suction and transmission filter are both changed every 400 hours.
