5. NOTE: Always replace oil filter (A) while changing transmission-hydraulic oil.

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

6. Apply a film of oil to new filter O-ring and install new oil filter (A). Hand tighten plus 1/2 turn with 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 transmission. Oil expands during operation and could overflow.
