07 RX350 AWD tranny, transfer case, diff oil question
Hi,
It's 2007 RX350 AWD, got 91k miles. None of the
tranny, transfer case and rear differential fluid have been changed before.
Manual said tranny fluid not needed change unless driving under extreme condition or towing.
Well, it's been a CA car that never gone off road or tow anything.
Does it also mean for transfer case oil and rear diff oil?
Even so, is it better to change them and what is the longest interval one should do it?
Many thanks.

I got the toyota dealer to change the tranny fluid for me at 75K miles when I was getting a brake job. Got the car at 30K miles and really had no idea how it was driven. I don't believe in lifetime fluids either. shifts were noticably smoother afterwards. From what I hear, it's pretty tough to DIY the transmission fluid on these cars. cant answer about the other fluids though.
