The maximum transmission fluid interval is 150k miles for 10R80 regardless of year. For owners who are towing/hauling frequently or doing high performance driving, that interval should be adjusted down.Why is it folks are changing their tranny fluid and filter often? Only because of shifting problems? Paranoid? My maintenance schedule (2021 Gen 3) only shows to check fluid level all the way through 200K miles and no filter or oil changes.
