So after doing a bunch of searching regarding tranny fluid changes on the RX350 (not the 330), I've discovered that I screwed up and did one drain and fill with Toyota T-IV fluid (4 quarts). ![Mad](https://www.clublexus.com/forums/images/smilies/mad.gif)
I've read in some threads that the WS ATF is supposed to last the life of the car (which is hard for me to believe) so I was planning on doing a drain and fill every 10k miles or so.
I also read that WS ATF does not play nice with other fluids so my question is, should I pay for a complete WS ATF flush? Or do more frequent drain and fills to slowing bring my total WS AFT ratio back to 100%?
If the transmission holds about 14 qt or so of fluid, 70% of it, in theory is still WS ATF. That number will increase with constant drain and fills.
Any thoughts?
