I own a 2004 RX330 with 91,000 miles on it. I am ashamed to say that I haven't ever changed my transmission or differential fluids in the 7 years (purchased in 2003) I have owned the vehicle. I am considering keeping it for another two years which will put me at appx. 120,000 miles. I am prepared to replace the timing belt and do the other specified maint. items called out at the 90,000/100,000 mile mark. I have two questions:
1) should I consider the fluid replacements now at this late stage or take my chances going forward? I've heard that once you've passed a certain mileage level without replacing the fluids, it's best to just let it ride.
2) What are the odds that the transmission and differentials will be okay to the 120,000 mark?
Could use some advice.
