just reading this thread as i found it interesting that the LS460 has a "sealed" transmission and you cannot flush the system. Even my older LS400 says that the fluid shouldn't need flushing ever.
perhaps. Interesting discussion. I know when i took my lexus to the dealer for service they reprimanded me for putting Mobil 1 synthetic in the transmission when i've been running it for 8 years on my cruiser.

Just wanted to give everyone an update. I got busy but finally was able to take it to the dealer at around 74k miles and asked for a transmission flush.
The service adviser declined about four times and explained to me that it does not need it until 100k. I then told him that I fully understand his explanation and that I am requesting to have it done so he happily complied.
After the complete flush and $260 later the 200 seems to be driving the same and I will let everybody know if anything changes...
