I was going to suggest Walmart.com,nobody can beat their prices in my search for real deal Denso sensor and the front 02 sensor very easy to get to.Took me longer to get my tools and jack up one side of car then it did to replace sensor.Easily accessible.Glad to hear you got yours done.

Just reminding that only ca 1/4 of the oil can be drained each drain. I Have two LS400. Also think the six times drain and refill feels most safe. I want the oil to have fresh additives and dispersed wear particles in low amount. Nothing else. Trying to flush out deposited stuff feels like a very bad idea. The drain and fill method is a bit wasteful of the oil but it works reasonably well.
It is possible to calculate how much of the old oil is left after 6 times 2 quart changes. The Trans holds ca 9 quarts total.
(7/9)^6 is the old fraction that is left. ca 22% . Hence the new oil share will be ca 78% IF you drive and mix the oil well between the changes. After this I do 2 quart changes every motor oil change. This will mean that over time the average age on the transmission oil additives etc will be approaching around ca 3 years or so in the long run.

I did a pretty deep clean of the car. Vacuumed, cleaned and conditioned the leather, and cleaned the dash. The ES300 I got for my mom yesterday is getting the same treatment tomorrow.

I tried giving her my LS at one point when I still had my Toyota Matrix XRS to drive but she said it was too big. The ES isn't that much smaller but she likes it's better lol

Transmission oil changes...It IS possible to get 3 quarts or even close to 4 out but that only worked for me the times I had the car jacked up in front for a few weeks for suspension work. I was told that some more of the ATF seeps into the pan given time (and the angle with front lifted probably). Normally when I jack up the car straight up on a car lift and drain directly I get less then 2 quarts out. Done that several times on two different LS400 .

Finally took care of the rear brake pads and rotors. Brembo blanks and Bosch pads. I didn't get a comparison pic of the pads but they were nearly gone!
