Today, I went to Toyota service center to get my 2017 RX350 engine oil changed.
I asked a service rep that whether transmission oil can be changed and he said yes it is possible at 60k.
Is it true? I thought our transmission is not servicable but if it is possible, I like to get serviced since I do not believe in life time trans oil.

And as usual these things are YMMV on this.

The alternative for a full exchange, according to the book, is very complex and time consuming that would cost at least twice as much.
You can also do drop & fill but in the end to achieve a FULL exchange it will cost you as much as doing it by machine plus all the wasted time, (yours)
I'll have mine done by the dealer when the time comes at 50K that way I'll know the work is done by qualified people.

my understanding with the machines used by shops - they using pressure to flush out the fluid through the cooler lines.
speaking strictly about changing out the fluid - i have on other vehicles disconnected the output line on the tranny cooler. i add a quart or so of fluid in and then start the car for a a few seconds (10 maybe). The fluid pumps out through the output line i disconnected into a catch basin and then i replenish the transmission with new fluid. I rinse and repeat until the fluid coming out is clean.
its sort of like a flush - but i consider it more of fluid "exchange" of dirty fluid for clean fluid - seems like the tricky part with the RX is making sure of the proper fluid level once all is said and done.

The Drain the Refill procedure on these vehicles are tedious compared to say the old school drain bolt and dipstick. However, Flushes are a controversial bit. IF you have never switched fluid, and are approaching 60k or beyound NEVER. Drain and refill is the only way with mileage going up. Safely I`d say first check if transmission flushes are allowed on these vehicles, and if your planning to get it at a early/half way 25k/2 year mark , since if anything does goo bad you have warranty to fall back on.

Exactly, that's why it's best done by the machine. Lexus dealers use a MOC (I remembered the name this time) and it takes in consideration not only the amount of fluid coming out but also the temperature difference between the 2 fluids in/out (if there is any). All this is getting way too technical, it used to be fun now the machines are taking over.

Is the 8-speed in our rx350 a ZF? i really hope not... I really have a lot more faith in Toyota.
but here is what ZF says about their transmissions.

This transmission is not made by Toyota, so Im really not that confident in it's lifetimesness...
It's not even Japanese (insert genuine horror face)
The people who made it thinks you should change it.

The ZF video is informational for sure, since ZF transmissions were the leader of the whole Lifetime stamp automobile companies were using to justify no longer servicing their transmissions .

A lot of truck use it and has been proven very durable, FCA charges a premium for this tranny.

While ZF makes the greatest longitudinal 8 speed out there, its FWD/transverse transmissions specifically the 9 speed is absolute garbage. Thankfully the unit in the RX I believe is an Aisin unit same as the Volvo XC90, to a degree. Aisin is a long time subcontractor for Toyota vehicles, and as usual with alot of companies that work with Toyota, has a 30% investment in the company.

I wonder if the the new supra use the ZF...
anyways. I'm glad i found out before i went and bought ZF fluid to perform a fluid change.

Hi all -
Requesting some help/knowledge please. I'm at 40k on our 16 RX350 F-Sport AWD. I really want to replace the differential fluid sometime within the next 10k miles but trying to do a little homework before I tackle it. I've tried searching this site and the interweb in general (along with the manual). The rear looks fairly straight forward, but I see no information about the front. Does anyone know if it shares the housing with the transfer maybe? Many thanks!

New to the forum and first time Lexus owner coming from an '09 RAV4. Bought a 2016 RX350/FWD/Silver/Base model at 36k miles. Attempting to do an ATF drain and fill this week (any tips and tricks are most appreciated). I'm a gearhead and did all the work by myself on the RAV and it was running as good as new when I traded it in at 153k miles. Planning on the same with the RX. Wish me luck
