If your ES is due for a 'complete' fluid change, I'd take this chance to replace the tranny pan gasket while your at it & clean the filter mesh screen at the same time (this should be good for several years before you have to change the gasket again as a preventitive measure). In between that time (sounds like your very fussy like me with fluid changes) I'd just do a 'drain & fill' methon every 30k miles or 2 years whichever comes first........especially if you switch to Amsoil synthetic ATF as it will last much longer than the conventional Toyota Type IV fluid. Just my suggestion as that is exactly what I will be doing. B)

OK, so let's say that I own an ES300 MY97 that has the discolored tranny fluid and is low mileage for the age, but hadn't had the tranny fluid changed in 40K? Total mileage is about 80K right now. The car has not been abused in the sense of stoplight burnouts (or attempts there of) or acting like it's a manual and unnecessarily shifting from low to drive for instance . All the other fluids, oil, brake, and coolant has been changed at scheduled times, but my wife neglected to do the Tranny fluid afte our last visit to the Lexus shop at 30K. All other work was done third party, i.e. Goodyear or some other shop and that is why no one came out and mentioned anything to her about it. :chairshot: So what options and steps should I take? I do have the smell from the tranny case and the fluid is a dark color. I like to change it out ASAP, but confused whether to flush the system or not. Any suggestions. Also for an older car should synth in the tranny be ok as opposed to the regular dino stuff? Thanks for any help.

I am in about the same situation as Henry... What exactly should I do? Should I do a flush? Or should I just do a drain and replace?
