it's a little square box about 8 inches on a side. As I recall the Borge Warner is larger, longer and with rounded sides. I use a plastic juice bottle marked at exactly the right amount of fluid so I don't have to screw around with "adding a little, adding a little, Oops, removing a little". I fill the bottle to the line and poor it into the transmission and call it good. I change it every 100 hours at the same time that I change my engine oil and suck it out with a vacuum pump.
