ATF inspection only for life of car? Any high milers here who have never drained ATF?
so every lexus made this century only requires inspection of transmission fluid, no drain/replace?
I see lexus website recommends inspection at 30k 60k 90k... and then 150k.
What am I supposed to inspect for ?

With most conventional torque-converter automatic transmission fluids, look for a relatively clear, reddish fluid-condition that doesn't show any signs of burning/overheating, darkening, foul odors, opaqueness, or excessive amounts of materials in it which could indicate wearing off internal transmission parts. Some newer transmissions, sad to say, don't even have a drain plug...it can be difficult to even get to the fluid itself.

So you would buy a new car instead of making the tranny last longer

Here's a good article, BTW, on how to deal with at least one of them.

Think about it. A drain plug is always necessary and nice to have, why would they not put one in?
They lied and tell the general public there is no drain plug so people won't change the fluid.
Deception for financial gain, understand?
Don't believe everything you read.

My old jaguar had a "sealed" transfer case. Some guys on the forum, including me, opened it up from the fill point in an attempt to suck out the fluid and put in new fluid. We all found them to be completely dry. All of the fluids had disappeared through heat or some other way. The gears were just grinding on eachother with no lubrication.

Though not the best answer, the dipstick, to some extent, will give you some clues. If the fluid is relatively clear and reddish, as it should be, you will probably see the notches or markings through it on the stick. And if there is a burnt smell, you can probably detect it if you get your nose close enough to it.
Some places try to sell transmission flushes, where a pressure-machine pumps detergent all through the transmission to restore its internal cleanliness to virtually new condition. (Pat Goss, of TV's Motorweek, is a big proponent of doing that every few years). The idea behind that is that, on a typical transmission fluid drain/replacement, even with a new filter, some of the old fluid and dirt/sediment doesn't all get out, and remains in the transmission contaminating the new added fluid. I agree that flushing, if done correctly, can keep the transmission in better shape, but it is costly, risky, and, if not done right, can either inadequately clean the transmission with too little pump-pressure or damage seals and valves with to much pressure. And, if a transmission is very old, with a lot of miles on it, really dirty inside, and has never been flushed or had new fluid, flushing can cause leaks that weren't there before by blowing out pieces of old or corroded seal/gasket material until it looks like Swiss Cheese.

You'll not likely hear from any hi-milers who have never drained the ATF - if you do their transmissions will be on their last legs. Even full synthetic fluid will deteriorate significantly by 30,000 miles and be gross looking and feeling by 100,000 miles. On Camry forums, some 6-speed automatic owners have been reporting transmission failure at under 100,000 miles.

BMW started with the lifetime fluid, and eventually changed it to 90k fluid, I think all the cars rolling out with lifetime fluid, usually require a fluid change at 75-90k.
My buddy has an 09 Camry with 120k on the 6speed auto, still shift fine, Im wondering when its gonna have issues and if he should change/drain the fluid.

So it is very true and accurate that the fluid don't have to be change and the tranny would function perfectly to 100k miles.
It is only for folks like me that want the tranny to last to 200k, 300k that need to change the fluid.

Even with "lifetime" fluids, I've changed them all at least once by 30k. MB had lifetime fill on my dad's old S500. They refused to touch it until it started having issues at 45k. Never the same after that. My FJ has had 2 drain/fills so far and now its at 55k. My S550 had a complete flush around 30k. The Explorer had drain /fill at 75k and again at 95k. I ignore that nonsense and take care of it like older transmissions.
