I finally got the results for my transmission fluid analysis after 3 weeks of waiting. Still waiting for my oil analysis to come back. I added 1.5 quarts in this OCI because the drain plug was leaking. That's probably why the numbers are more favorable this OCI.

You can save time and money and do a drain and fill every 45K from now on.

Thanks for your UOA of the Mercon LV. Just curious how much atf did you know to add without a dipstick from the leak? Or does your vehicle have a dipstick. Since the drain and fill on this transmission is so easy and cheap to do it's worth the $20 to do it every 15-20,000 miles if you want to keep your vehicle for 200,000+ miles. I do it myself, I drain it cold and put back in the same amount of new cold ATF.

The 6F35 has a level-check plug. You should check it on yours at least once. You don't know if yours is low or high and just adding back in the same that you drained maintains that level.
