I'm 100% going to do this. I do loads of twin axle caravan towing and see this as great preventative maintenance. My old XC90 developed a transmission fault which manifested itself towing in the French Alps, it was fine once back at a sensible altitude until the following year at the same point more or less. It then started happening whenever I was towing uphill and the torque converter locked up.
I bought a newer model and want to prevent the same thing happening again. I changed the fluid on my 1st car twice and have changed it once on my present car for the mobil 3309. I've got enough left for a sump and dump so will fit this at the same time and top off. can't do any harm at all.
