Transfer Case Fluid on AWD 2000 RX 300 with LSD
Sorry if this sounds like a "repeat question", but on this model/configuration:
Is there a separate entry point to refill the Transfer Case, or is all replacement oil added via the ATF access (and that one entry point supplies the transmission fluid, front diff, and transfer case)?
I have seen the photos in another thread related the changing the fluids which showed two plugs for draining, one for the Transmission and one for the Transfer Case. But I did not see where Transfer Case oil is refilled from.
Thanks

For plugs that needed to be filled with gear oil (not ATF), then see my thread here, https://www.clublexus.com/forums/rx-...sfer-case.html

What kind of tool did you use to open the transfer case drain plug? Is it the same as the rear diff ? 10 m Allen wrench? Do you have any pic for the front differential drain and fill ?

For the front differential, see this post by TunedRX300, https://www.clublexus.com/forums/rx-...er-change.html (see post 3) he calls it a transfer case drain plug, but I call it front differential
Just go by what the photos show and the types of tools used.

My dealer flushed the tranny of my '99 AWD right before I got the vehicle (yes, I know many of you won't approve). That means that when I change the rear diff fluid myself, there's nothing I need to do on the front portion, right?

Incorrect, you will still have to change the transfer case fluid.

Ah, now I remember. That funny hexagonal fill plug. It's been several years since I did this on my daughter's. I thought I made all these careful notes on the computer, but I can't find them. I looked two posts higher and clicked on Lexmex's link (I should have done that first!) and that refreshed my memory. I can't seem to recall which drain plug gaskets go where in every case. I wrote down that the "bottom" or horizontal tranny plug gasket is 90430-18008, the non-shiny one, and that the tranny drain plug on the side is the shiny compressible (looks like two layers of metal) 12157-10010.
I also think the front transaxle drain and fill plugs use the 12157-10010 gaskets, but I can't remember what gaskets the drain and fill plugs use on the rear diff. I could start another thread, but I'm guessing you'll know, Hypervish.

Thanks, CarGuy!
I should have said front transfer case instead of front transaxle.for the front. I found the info the dealer gave me six years ago. They agree the crush washers are used for the rear diff drain & fill plugs and for the (front) transfer case drain & fill plugs. They also agree the downward-facing tranny drain plug uses the flat aluminum washer. They recommend a crush washer for that side transmission drain plug, though.
I really doubt it matters much. As everyone points out, the correct tightness is probably what's important. I appreciate the help with this -- thanks!

Hi Lexmex, I got some good knowledge from you and others in this forum and I thank all of you for it. I just changed my trany oil at 103K on my 2000 Lexus RX300 and was going to change the transfer cases both front and rear and also the differential cases both front and rear, and hence purchased 4 quarts of Royal Purple 75W90 after reading your other post on transfer case.
But now in this post i read that the front differential does not need additonal gear oil, as it draws its oil from the tranny, is that right ? So i will only require 3 quarts of gear oil ie 1 qt each for front transfer and 1 qt each for rear transfer and differentail. Am I right on this ? Pls let me know.
I intend to change it on the weekend of thksgiving.
Thanks
