Cvt gear box

[byrnew2007]

Hi all, i am wondering when does the oil need to be changed in the cvt gearbox. I have a Lexus is300F. Also are they known for giving trouble ect. 

 

Thanks

It is meant to be lifetime but probably worth changing every 100k miles.

I've not heard of IS300h transmission issues on these forums - the IS300h has been around for 5 years now so if there are long term issues we will probably start to hear about them around this time.

In every case I ever heard, since '80, "lifetime" manufacturer's claim about transmission oil/filter was easy translate to "until the end of warranty" (I could bring a few "funny" historical examples). What I read about CVTs (ok, mostly nissan not toyota/lexus) nothing changes. I personaly think 100k miles is much too long, I would try like 60k, maybe 80k. BTW if we'll start to hear about their problems, it could be too late for oil changes.
