As mentioned before, didn't look into a leak on the 03 S80 T6 as my son had the car. When I got to it there was a large of amount of good size metal bits in the transmission pan. Complete flush and new filter and it's driveable only in manual mode.
Even then have to baby it through shifts, grades and inclines in the road or else feel revs sends it into Limp Mode. Ordered some 50W transmission fluid and will mix with existing to see if it will make it more driveable as he doesn't like the 03 Odyssey
Have used the 714 20W for years but haven't had a trouble transmission lately so forgot about it. Purchased last jug of 50W as it's little use and never on my radar till I saw it on Paragons website. The use of 20W cured a few transmissions besides saving others.
