Replying to: ateixeira (Sep 04, 2009 10:41 am) The fluid was still black after 2 drain and refills. I did a "safe" flush...12 quarts were sucked out by special machine and replaced (no detergents were used). Now before it gets black (15,000) I will keep up on the drain and refills. I will never let it get black again. Thanks

Replying to: arodory (Feb 18, 2009 3:34 pm) A single, simple, drain and refill (4 qts) will NOT result in anything close to prestine appearing ATF. It takes at least two 5 quart drain and fill procedures to get to decent looking ATF. Even my Lexus dealer service did not know that the front diff'l case must be drained separately and has its own drain plug, that's why 5 quarts are required. I went through the above procedure, as the ATF was burned and dirty, at only 40,000 miles and am now at close to 80,000 miles and am keeping a close eye on the ATF condition.
