Mann777,
Thanks for making this a sticky.....how would you go about draining the fluid from the whole tranny? Just remove the drain plug or is there another drain to get the fluid out of the torque converter? The directions mention 5+ quarts so just wondering....

Dran bolt lets about 3 out. Measure what comes out and fill that amount with new fluid. Start engine 3 seconds and remove drain bolt again and lets about 3 out. measure and refill with equal amount. Do this until comes out cherry red. I used 12.5 total when I did mine. After you get the cherry red coming out, do the overfill check as outlined in Mann's procedure.

The dealer told me that there is no need to drain the transmission at 100,000. I really wonder about that? What has been the experience of other in having the dealer do this service?

Read the blackstone report on this link and then decide.
Read the ATF WS report from Blackstone on this Lexus GS350. It basically says the fluid is deteriorating in the 80-100k range. The procedure Al details works on our GX's. I did this on my wifes GS350 and it is not difficult.

Can you check the link or give more detail to search for?. The link appears to be broken. Thanks, Al

It's not hard to make a sticky when you're the mod.

The same PDF has been posted for several years but the thread was just made within the past 2 weeks.
