Transmission Refill vs Flush at 60K miles
#16
Hello Jack... as for what brand of oil to use, there are A LOT of great name brand oils out there.. Pennzoil, Mobil 1, Royal Purple and the list goes on and on. Whatever brand you use just make sure it's Synthetic... 0w-20. Personally I use and have used for years Mobil 1 extended performance.. It's supposed to be good for 15K miles... even so, I'm OLD OLD OLD School. Even though Mobil 1 EP is rated for 15K mile oil change interval, I still change my oil and my filter every 5K miles. I know it's over kill but it gives me peace of mind. Plus now that I'm retired I probably don't put but maybe 7 or 8 thousand a year on my car so it takes me a little while to get to 5K miles.. Lexus calls for oil changes every 10K. Personally that would be the longest I would ever go between oil changes.. You're probably good to go using Mobil 1 EP every 10k miles.

My local Lexus service manager has been at the dealership since 1991. He is as straight a shooter as I have ever seen. I asked about the transmission, and he recommended not servicing it unless there was some kind of problem, or you were getting up closer to 150k-200k miles. And even then, only if it was showing signs of a problem.

Here in western Canada the 3 Lexus dealer I talked to all recommend doing a drain and fill at 100k km.Got mine done at Toyota dealer at 100k km,It’s got 18k km after drain and fill no problems. Nothing last forever. I know a IS 250 owner who’s lifetime tranny fluid failed after 300k km.The reality is most people don’t keep their car past 200k Km.

Just joined this forum after buying a 2016 ES 350 certified with 35,000 miles. I will be doing a drain and fill soon. I have spent a lot of my career doing oil analysis and fluid analysis on aircraft and heavy machinery. I have never seen a fluid used for lubrication / pressurizing that does not break down. Heat is the number 1 killer. Many times we tested the fluid and did not recommend changing it. Without the expensive resources to test, I will just change it utilizing the drain and fill method so only a few quarts are changed. This method (supposedly) keeps from introducing all new fluid which can lead to issues on older transmissions.
With that said, I could be 100 percent wrong. I am not attempting to convince anyone to do anything different than what they are comfortable with. Whatever works for you is the best thing regardless of anyone else's opinion.
A lot of great advice on this forum, thank you!

rmak, you're 100% correct, drain and refill ONLY, no flushing. It takes 2 qts. Doing this every 50-60k miles and your tranny should last much longer. There is NO such a thing as lifetime fluid - bunch of BS.

Interesting: The AISIN company that has been making Toyota automatics for 50 years acknowledges that some car makers suggest never changing the fluid, but then goes on to suggest changing it every 2 years or 12,000 miles to maintain "improved shift feel, fuel economy and longer transmission life":

I'll be doing flush on my 2012 ES350 with 86K miles. Some lexus dealers will not do it, other will do it.
The ones that do not do it, will keep telling you scripted line from your owner manual "its a sealed unit blah blah..." Its totally useless conversation, I can read it in manual myself.
The ones that do it, will explain that its safe, and can not hurt anything.
If you read you manual careful, it will give hints that during towing, they do want you to change it... so its not completely black and white.
Toyota dealers will do it for your lexus (at least the ones I called). Toyota and lexus dealer prices are about the same ~$270 for a flush. The flush is not your traditional high pressure flush, my understanding they connect tube to the machine, and let transmission pump drive the fluid without additional pressure. New fluid comes in, and old one comes out. With under 100K miles, this is completely safe. I would be more concerned doing this for the first time at 200K miles.
Let it be $300 that I waste.
I know there is a lot of debate about sealed transmissions fluid change. Take a look at transmission fluid pictures that never was changed at 100K or more miles, its turning black and looks nasty
When people drop their transmissions pans, it has a lot of metal shavings..
People will say that they know someone with 200K miles and fluid was never changed, I know some of those people too.
I do not see any harm in doing at least one transmission flush before 100K miles if you want to keep your car to 200K+. I think of it as an insurance policy.

This is excellent. People keep saying "toyota engineers are smart, and they said do not change it blah blah..."
However, transmission is NOT designed by toyota, it might be designed FOR Toyota by Aisin. And AISIN itself is calling BS on "sealed for life".
I have a feeling that Lexus dealers that do not do it, are simply going by the book. Its easier for them this way. Any problem with transmission, they will say "we just did what the book said, not our fault". I can see that this makes things easier for them,

Some dealers do not have the machine to do the exchange nor the tech proficient in its use!
It's interesting that on that link at he bottom of the page on the right with an ATF machine picture it says....Aisin recommends the use of ATF exchange machines.
