Maintenace Interval '04 Ls430

[curiousB]

I just went through my old records for my ’04 LS430 and saw my dealer replaced differential oil and transmission fluid at 33,203 and again at 47,505. I saw on this forum a maintenance schedule and TSB (http://us.lexusownersclub.com/forums/index.php?showtopic=44661) that seems to indicate transmission ATF fluid is a non serviceable item. Is it lifetime lubricated with only the need for periodic check to ensure it’s topped up?

Also the schedule I have doesn’t seem to show a change interval for spark plugs or differential oil? Anybody got that info handy? I tried this web site (http://www.edmunds.com/maintenance/select.html) but it doesn’t seem to ever show changing differential oil, transmission fluid or spark plugs.

The owner's manual may have some more detailed maintenance scheduling.
