Toyota ATF is great fluid. I am a fan of Amsoil as well AND adding a tranny cooler as extra insurance. The #1 leading cause of tranny failure is heat.

Hello Mandy,
Congrats on your posting. You have been fairly busy also with over 1200 post per year/100 per month. How do you do it with your full time job? Don't get me wrong I really enjoy reading all the posts. This is one super forum. Some service writers are not too fond but that is their problem. A lot of good information is shared. Thanks to all.
Don

sicklex,with all due respect (and obviously you`v earned it) you think the Toyota fluid is great fluid??

LexFather

I think it is solid, the Type IV fluid. In newer Lexus models as someone stated the tranny is sealed and you don't replace any fluid for over 100,000 miles/life of the car I believe. That is a lot of confidence. Lexus/Toyota tranny failures are not common at all, usually owner abuse or a rare bad tranny.

That said I upgraded to Amsoil in a RX 300 AWD (which already has a tranny cooler) and in a modified GS 430 (where I added a tranny cooler) and both vehicles have over 180k miles on them and the transmission has held up (crosses fingers)

On the 450h I haven't touched the fluid and it has a CVT and it has been terrific.

Out of curiousity, I wonder what fluid the LFA uses (need to find out). I am sure the IS F uses the same fluid as the RX and that is a car tested at the track and expected to be driven hard.

Let me find out.

did you notice that the amsoil fluid seem`s to be a little thicker? i have wolf`s head in my trans right now.but i may go back to the toyota fluid,or the castrol multi-import fluid.

LexFather

Honestly not sure if it was "thicker". A lot of the 2GS guys believe in it here though.

The other thing too is make sure ALL the old fluid is drained, so this requires buying more fluid than the reservoir holds so all the old fluid is replaced. Of course that is if you replace/flush/drain.

What are your thoughts on wolf's head, haven't heard of it.

lexus114

well the wolf`s head is sold by amalie out of florida. it`s a fits-em-all full synthetic fluid,that performs very well. but it does firm up the shifts some,especially when cold. i like it that way,some may prefer the slippery shift feel.

I'm using the Castrol Multi-Import Fluid in my RX and it shift's perfect. No problems. It's a semi-synthetic though unlike Amsoil.

Don, thanks. Still enjoying the grille. The wife that is.

This is one forum that I truly enjoy being a part of. And I am a member of a quite a few. And I must say, not all forums are created equal. The CL is unique. This forum is composed of the real DIY'ers and the ones who sometimes have no clue.

All good though. I like it very much. This forum is my recluse.

lexus114

depends,how does the fluid look ? if it looks pretty good,wait until 30k.

ycl1688
