Also I flushed a lot more then was written. I used a full 12 quarts through the whole process. Which is more then needed. But I had it laying around.

Is that okay flashing only by draining without change filter and o-ring?

Doing a drain and fill, without touching the filters is certainly fine. Although you'll only be changing about 40% of the fluid that way (about 4 quarts out of nearly 9 quarts total). Be sure that you refill with the same amount of fluid you drained out, the CVT can be quite sensitive to proper fluid level.

Thank you for the writeup!
What is the size of the barb fitting? and the line out? 1 inch?
Any clear tubing (from a Home Depot plumbing Dept.) would do?

15) You've now removed the return line from the cooler This is the line you will use to pump out the old fluid. Install a double-ended barb fitting to the return line and run another line to a receptacle marked with fluid capacity. I used an empty gallon windshield washer fluid bottle that I marked with quarts.
