I thought T-IV was the recommended fluid. Drivewire.com lists this as the preferred solution and labels it as synthetic.

I also see it as the fluid of choice at this Lexus page:

Is there something better than the Toyota T-IV?

I still don't know why Type-IV is labelled synthetic by some.

No I did not, but I will do this when I drain it again on my next oil change. Thanks for the tip
Quick question though. Now when I fill up the fluid as usual, will the gauge show me the extra quart that I removed this other way? I don't want to be a quart short.

When you say gauge, I suspect you mean dipstick, right....
If your refering to dipstick, yes, the dipstick level is connected to the transfer case and trani which uses the same fluid containing system.

Yes that's what I meant, sorry, I word just escaped my mind at the moment
Thanks for the info. This brings me to another question that I could probably find if a search, but lazy :-) so the transfer case takes transmission fluid and no gear oil?

Gomer1,
Sometimes the term transfer case gets interchanged. Same is true with A/F sensors and O2 sensors. So let me see if I can clear some of this up.
Let me bring up the earlier picture again. On the left there are two drain plugs...one on the left and one on the right. The one on the right you recognize as the one for the transmission that uses ATF fluid (Type IV Toyota). The one on the left is the one that Fern is referring to. This is sometimes called the transfer case or front differential. If you drain this one, ATF will also come out (about .5 L). KEY POINT: Both the transmission and this transfer case or front differential (as I call it) use ATF that is filled up through the transmission fluid dipstick (yellow handle). You pour the ATF in here and it will find its way to both the transmission and transfer case/front differential. They are interconnected.
BUT, I need to bring up something else in my next post.

In the photo below the areas you just saw in the picture above are in blue.
Now, you see the area in red...well this piece is also known as a transfer case. However, this only exists if you have AWD. It used .9L of 85W90 GL5 Gear Fluid. You can use 75W90 without issue. I like Royal Purple MaxGear, but there are several others out there such as Mobil 1 75W90 gear fluid that is quite popular in this forum and also Amsoil and Redline. I have done a DIY on this https://www.clublexus.com/forums/sho...d.php?t=214000 and also the rear differential on the back axle that uses the same fluid.

I'm a big proponent of tranny flushes. I've always done tranny flushes on all of my cars and none have ever had tranny problems (130k, 240k, 180k miles on my previous 3 cars). BTW, i BEAT THE CR@P out of my cars and frequent changes to fluids have always been good to me.

If you drain both, will there be any false positive readings on the dipstick? Or am I over analyzing?
Asking because it seems owners here have a bunch of different ways to take care of their tranny.

If you plan to do drain and fill, I would suggest to let the trans cool down, Note that is not cold.
Basically you are waiting for things to form a sediment with some flow. If it is tottaly cold, the sediments might stick to the pan and not flow out, If hot and vigorously stirred the sediments may be tottally mixed and spread out.
If you plan to take the pan off, then cold and cooled will give you the same results.
The transmission fluid circuit connects the two chambers (and many others). The level is checked with engine running, Step by step instructions were posted before.

ps: Since my know how is not extensive, you may like to wait and read what others have to say.

So what would be the total ATF capacity for an AWD RX300? I just did a drain-n-fill myself (got exactly 4 qts out) because the dealer didn't do it at 90K. Just wonder if I should do another drain-n-fill to get it cleaned up. Thanks.
