I usually buy a 9 quarts of ATF. I drain what I can out of the drain plug. I fill up back up to previous level about 3 quarts. I drive around for a few miles. Drain and fill, drive around. The drain and fill one last time. The 3rd time draining the fluid, it looks clean. 9 quarts or even 12 if you want to do it 4 times, is a lot cheaper than $99-$139 at the local lube place. I need to do in on my SR sometime soon.

I just want to tell you both good luck, and we're all counting on you.
