I hope that's right. I'm fixin to start using my truck to make a living in a couple of weeks pulling campers and mine has that same tranny(2000 F-350 PSD, 39,000 miles) So far I haven't had a lick of trouble with mine:pray: Main thing is (Maintenance) Change that fluid and filter every 20 to 30,000 miles. Probably more frequently if used in a 400 hp Lightening. Wouldn't you say so Marc?
