I did a drain and fill at 98k miles, currently at 140k and the fluid still looks cherry red, but will do another in the spring. The good thing is these cars is they have a dipstick, so if you can do an oil change, you can do a drain and fill on the tranny.
To put things in perspective, my 2006 GS300 also has "lifetime fluid" with no dipstick, but when I asked a dealer if they would service, they gladly obliged concurring with the fact that lifetime fluid is whatever the marketing department deems a lifetime, and flushed 13-14 quarts through the system from $300.

I am going to do this as I am at 122,000. My question is if I drain thru bottom bolt on pan does just 4 quarts come out and then I put 4 quarts new (Valvoline MaxLife) thru dipstick?

I actually just dropped my Lexus off last Sat and decided to go ahead and let them do the flush. Costs $305 through the dealer. No hands dirty and I had the money to get it done. There is a laundry list of things that need to be done since taking it in, but that's for another thread. LOL
The last time it had been done according to records online via Lexus owner portal was the 120k service the odometer actually red 117k. Now it's at 191k. I don't foresee there being a problem. It had no issues before going in. I'm exited to see if there will be any noticeable differences. Maybe smoother shifting or not hunting for 1st sometimes.

Was getting ready to just do the drain and fill thru dipstick (using Toyota WS after thinking about it) but after looking at the dipstick liquid very carefully it looks clear. The smell also does not show a trace of burnt intensity. So, now I am feeling conflicted just to leave alone even though or go forward. After looking thru all the various post seems 50/50 on what to do.

Well... I’ve been there before. You can just leave it alone. Or... if you don’t know when the last time it’s been done, then you know it won’t hurt to change the fluid. I’m a big believer in leaving it alone. Personal reason I changed mine was no issues whatsoever, and I’d like to keep it that way. In the past I had an issue and did a flush in a Honda Accord and it helped. And on the other hand I owned another vehicle and after I did a flush it started having issues! Here we are... back to the 50/50. LolAlso if you change it and you didn’t know when was the last time... you’re getting on your own interval! Let us know what you decide, and why. It will add to the 50/50 statistics.

Well as my wife has owned the car since 15,000 mile and now 122,000 it has never been changed. Every other car I have maintained I have done at 30,000 miles so letting it go is so counterintuitive.

I understand your indecision. Most of the time... leaving it alone we know like any fluid, will continue to break down as time goes on and lose it’s protection properties. With that being said, if it hasn’t been driven hard, and it’s not giving you any problems, and if it were me I would do the flush. Honda dealers I’ve talked to are normally against the flush. They just like to do a drain and fill. Normally that costs less, and it’s not as much fluid swapped like a flush would give you. Maybe a drain and fill every 15k times 2 would get you back on track for a flush down the road if you still own it. Just an idea.

Really good advice thank you. I’m about to replace the “ticking bomb” VVTi rubber hoses with the metal replacement and then will probably do a simple drain and fill and then repeat at 5,000 intervals several times. The car has never been driven hard and has been very well maintained. My wife intends to drive it for many more years.

Daleda, Hey just saw where you mentioned the replacing the rubber VVTI hoses with metal ones. Can you tell me which hoses you are talking about? Sounds like I need to do the same for 06 ES330 that I inherited. THANKS

As well as the trans fllter & cleaning the two magnets in the pan.....Since your there, I'd also change out the rear diff fluid as well as the transfer case oil.... 2 qtrs of Royal purple 75-90 gear oil, a Jug of Maxlife trans fluid as well as a Wix trans filter, clean the magnets & throw the pan in the parts washer for a bit.
