SYN3 is designed to be used in all three compartments (i.e. Primary, transmission, and engine). So the answer to your question is yes. As far as amounts, it will be around a quart. I do this: I drain the primary into to a large, two-quart measuring cup; I then put that exact amount of new fluid in. It should be touching the bottom of the clutch pack. If needed, add a little more.
