I should also add it takes only 7 fl oz of gear lube. I use Mobil 1 full synthetic. I fill it through the dipstick tube any you must go EXTREMELY slow. Almost a drip, the tube fills up and burps quickly. Takes about 10 minutes to get it all in there. A lot of people don't do this after the 100 hours it recommends to prolong the life of the PTO box.
