Transmission Service?

What puzzles me after reading all of these posts that seem endless, is why would a major company such as Toyota make such claims if they weren't true? Their reputation depends on quality, honesty, endurance and trust with their millions of customers. Many milestones have been achieved through the years that people thought never could be. Crossing the Atlantic
non-stop. A cure for Polio. And on and on. Granted these examples are certainly above the level of transmission fluid endurance but examples nonetheless.Who thought there would be a phone that would tansmit photos and data 25 years ago or that one would be able to receive phone calls in your car (with air conditioning). Music CD's, Bluetooth, etc. I'm obviously a believer and will adhere to the maintenance schedule as directed by the Toyota Company.

Never heard of a phone failing? Crossing the Atlantic non stop? - How many plane crashes have there been?
quality, honesty, endurance, trust?
you’ve forgotten the floormat problem that killed people which Toyota knew about for 2 years before they issued the recall.

I don’t know if anyone here owns a truck or owns one of those old rear wheel drive cars with a live axle and a differential in the middle. Those differentials almost never needed an oil change unless the seals went bad and the oil leaked out. The ESh transmission is similar to those old differentials. There are no clutches, no friction surfaces so the only wear is the metal gear contact points. Gears are designed so the surfaces mostly roll onto each other rather than slide. That reduces friction losses and increases mileage per gallon and also reduces wear. Any metal particles still generated by wear (and this should be very few) are captured by a filter and magnet. The synthetic oils now used are much more robust than oils of the past and since no water, acid or waste is generated, like in engines, the oils last for a lifetime, whatever that means. Honda transmissions have a clutch, even that of the Accord hybrid so there is friction and wear. This would generate more particles and the fluid would need to be likely replaced at greater frequency.

While unfortunately some people were killed (I don't recall how many exactly) it was never determined why effected drivers didn't put their cars in neutral, plus the fact that tests showed full braking will override full throttle and will stop a car. This also could have avoided fatal crashes.

Like the Audi unintended acceleration years before that was shown to be 100% BS.

Phones failing, Atlantic crossings and plane crashes. All very relevant (not) to a discussion about ATF fluid and the need to change or not change. Believe what you want and if conspiracy theories are your thing, go for it and change your fluid every 6 months. Failing that give empirical evidence that Lexus/Toyota is incorrect in their assertion that fluid is good for the lifetime of the car.
If their processes show one failure per million cars, would you still be unhappy with that statistic? How about one in 5 million?
I am outta here.

That's quite a straw man argument.
I was responding to the previous “straw man” argument.

Someone else raised them as “arguments”.

Toyota made the assertion that it’s good for the lifetime of the car, I didn’t say it’s not.
If their processes show one failure per million cars, would you still be unhappy with that statistic? How about one in 5 million?
wheres the data to back this up, or is this just a hypothetical argument?

Been a Lexus ASM for 23 years, maybe i've replaced 5 transmissions in older cars. We do NOT see alot of transmission problems so I wonder where you
heard that "so many of them need repair or replace"?

i know i will get attacked for this post
but
the lexus engineers are smart to engineer the transmission and fluid to last the 70000 miles of the powertrain warranty
after that the lexus dealership service departments, part counters and new car sales need to make money and stay in business
if lexus transmissions are lifetime how come they have so many of them to repair and replace?

Here's the bottom line folks: Lexus and Toyota have a reputation for very reliable transmissions and the failure rate is very low, combined with the fact that most customers just listen to the dealership and manual and DO NOT change the fluid. The vast majority of drivers do not visit messageboards and fret about changing fluids and what brand, when to change air filters and what brand to use and whether it has baking soda on it, etc etc

Interesting how Camry/Avalon/Highlander owners (based on what I read at toyotnation.com) are much more willing to change the transmission fluid than ES/RX350 owners even though all these vehicles use the same Aisin CVT, 6 and 8 speed transmissions. One would think Lexus owners should be more educated - especially in regards to science / business / marketing issues - hence should be more capable of understanding that modern CVT, 6 and 8 speed transmissions need fluid changes more that Toyota's of the past did because they are built more lighter duty, are lubed by a thinner viscosity fluid, operate at higher fluid temperatures and generate more wear debris such that Toyota was forced to install more wear debris trapping magnets in the oil pan and use an extra large, extra efficient felt transmission filter element instead of a smaller metal filter screen as was routine in the past.
But, no, many Lexus owners cannot grasp the above. Instead they are captivated by the thought that the "Lexus engineers" probably overbuilt the transmissions and made them able to survive many hundreds of thouands of miles without needing periodic fluid changes. "Lexus", to them, means something extra special and extra premium, even in regards to the drivetrain components of the vehicles.

Although not exactly the same as the CT200h, but I had a 3rd gen Prius which had, from what I understand the same engine and CVT tranny. I changed the fluid at 60K myself. When I compared the replacement red specialized fluid with what came out, there was a distinct color variation. Not sure if this was regular wear/tear or if Lexus engineers put some additional additive in the tranny fluid. I sold that car a few years ago at 100k+ and it still never had a transmission issue. I'd like to think of it as preventative maintenance although I have no idea what would've happened if I hadn't had changed it.
