Question is, is that exactly what your guys are doing or something else, less involved and getting away with it? There are many methods floating around here and elsewhere. My concern is most won't post up saying they did method x, y or z and 10,000 miles down the road the CVT crapped out.
If you believe your CVT fluid level is currently correct, you can do an easy(-ish) drain and fill. Place the car and your new CVT fluid in the same space (ideally, a garage), and allow them both to reach room temperature. Drain the CVT fluid in to a clean dry empty container by removing the CVT drain plug, and measure the amount of fluid drained. Add that amount of new CVT fluid back to the transmission.
If you go this route, the important bit is making sure that the fluid that you measure, and the fluid that you add are the same temperature, as the volume of the fluid varies a notable amount as the temperature changes. In my experience, this will take around 4 quarts (possibly a bit more, possibly a bit less) depending on temp and how long you let it drain. This replaces a bit less than half of the fluid in the system.
The Suzuki TSB recommends repeating the drain and fill 3 times (running for a bit in between) in order to get a "full" change (by my math you'll have about 70-80% new fluid at the end of that procedure).
