The maintence schedules in the 03 and 04.5 Factory Service Manuals indicate all that's needed for automatic transmission fluid and manual transmission gear oil & differential gear oil is an inspection at 15k, 30k, 45k, 60k miles, usless... see NOTE: (1).

"NOTE: (1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every 30,000 miles (48,000 km) or 24 months. Using automatic transmission fluid other than Genuine Nissan Matic J ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited warranty."
