Does anyone ever worry about there transmission dying if or when their car reaches over 100,000 miles if they have done preventative maintenance? Sometimes I have concerns because of the horror stories I have heard from RX300 owners.

 

I use synthetic transmission fluid and keep the same maintenance schedule as Lexus recommends. Also a search of the forum indicates the transmissions on the RX300 and RX330 are vastly different and better built.
I hope this helps
