As mentioned, and according to Lexus mtce records, the 30k mile service was performed, even though the car had just 24k on it. Work performed included:
"30000 MILE SERVICE NON WARRANTY 30000 MILE SERVICE FOR PREOWNED, REPLACE BRAKE FLUID, REPLACE AUTOMATIC TRANSMISSION OIL,REPLACE DIFFENTAIL OIL, REPLACE ENGINE AIR FILTER,CHANGE ENGINE COOLANT,REPLACE COOLANT,INSPECT FUEL LINES & CONNECTIONS, FUEL TANK VAPOR SYSTEM HOSES,FUEL TANK BAND, - PERFORMED 30K SERVICE"
and
"OTHER INSPECTION MULTI - POINT INSPECTION, VEH/ PREP GUIDE - ALL BODY OPENINGS, ALL ACC. , LIGHTS, GAUGES AUDIO,LOF,ALL FLUIDS FILL TO SPECS,BATTERY,ALL WIRES,BELTS, HOSES,TIRES & WHEELS. BRAKES .PLUS ALL CHASIS COMPONENTS, EXHAUST SYSTEM,ROAD TEST TO INSURE THE ENGINE, TRANS - MULTIPOINT INSPECTION,AIR FILTER,A/C FILTER,WIPER INSERTS BALANCED WHEELS,PROGRAMMED 1 KEY"
Anyway, we're getting a little off subject of the initial post.

Whether they actually did the fluid changes or not, I don't know. If I were to bet though, I'd bet they did. I've bought a lot of cars from dealers over the last 55 years or so and this dealer, JM Lexus in Margate, Fl, is without a doubt the best I ever dealt with by far. There is no BS and they try very hard to make you happy. Generally, they give you more than you'd expect. They advertise themselves as the world's highest-volume Lexus dealership since 1992 and it's easy to see why. I dealt with 4 other Lexus dealers in the area and got the normal dealer BS one would expect before buying my '11 LS460 CPO from JM. The prep/condition of the CPO's these other dealers offered didn't come close to that of the one from JM.

When I bought mine I knew it needed the transmission service (at least in my opinion), rear tires, coolant change (again in my opinion), brake fluid flush - but honestly I really don't mind doing stuff when I first buy a car - I have to think it's because I'm excited about a "new" car. But that wears off pretty quickly, luckily these cars are reliable.

I've been trying to attach my Blackstone actual report. Can't figure how to convert a .tiff from my scanner to something that the forum software will accept. So, here's their comments about my transmission fluid. See my OP for specifics about the car.
We found quite a lot of copper in this transmission sample, but everything else looks pretty good.
Since this was the factory fill of fluid, the copper is probably just due to wear-in of brass/bronze parts, and
we doubt it's a major concern, since the other metals are all fine. Universal averages show typical wear for
a Toyota automatic transmission after ~34,300 miles of oil use. As you do a couple more drain and fills, we
should see the copper level gradually diminish,

It looks great from what I can see. I see no reason why it needs to be changed until 100k.
That alarmist on that thread that Doublebase posted probably doesn't apply for our transmissions.
My only concern is the high copper wear but it could just be break in metals in suspension but it needs to be watched because some transmission fluids can be corrosive to yellow metals.
Thanks for doing this.

I don think it's a bad fluid, or something that needs to be replaced with a Valvoline product, or redline...or whatever. I just think it should be changed.
One other thing I wonder about is the TAN, I know with some machinery a TAN reading of 1.8 is too high...and a reading of 2.8 is on the end where you'll see wear of metals...copper, tin, etc. But I don't know about transmissions/tranny fluid.

The point I was trying to make is that it is not a lifetime fluid, just by going off that report changing it at 70,000 miles doesn't seem like a bad idea either. I'm trying to picture the fluid at 100,000, or 150,000, or 200,000 - because in this country Lexus IS saying its "lifetime". Everywhere else it's 60k mile fluid.

I need the tranny drained too. 105K and it was done before I bought it around 50k. Also need a oil change . Going to try Phillips Toyota in Leesburg FL?
Just had Toyota do a drain and fill on my 70,000 mile transmission. The bill was for 4 qts. and two washers/gaskets. Total of $123.17, $60/labor and $52.54 parts. I had them collect 4 oz of the fluid so I can send it off to Blackstone Labs for analysis. Pretty dark looking. I'll post my analysis when available. I think that even if the analysis comes back fine, I'll do two more drain and fills to have "fresher" fluid.
The Toyota dealer in Ocala has a gourmet chef lunch counter. Today they served fresh Maine lobster salad on a toasted hot dog bun with a side for $12.95. I'll be stopping in for lunch more often.
See post 35 for results.

No need to drive to Orlando. At least you have a price to compare. I left it overnight because they said the temp is important for proper transmission fill. They don't want a hot car.

What I think is interesting is the Blackstone comment about the copper levels being higher from wear-in of parts as this is the first time it's been changed.
This implies to me that the trans fluid should be changed after a wear-in or break-in period. Just like engine oil!
I'm no gear head but don't recall that as a regular practice like changing the oil after the break in miles on a new car.
It could be said that copper, being a soft metal is unlikely to cause damage like iron would. But I think any higher than normal levels should be addressed for long life.
Personally, I'd guess that the 3-4 qts drained and replaced now have my copper levels down by 20-25%. I'm comfortable doing another drain and fill with an analysis to see if my guess on copper levels, as well as other metals, is close.

Most transmissions are built with this in mind. The filter ends up being a remnant after the break in.

The magnet and filter should take care of any of the big particles that are far more dangerous. Unfortunately the really fine particles that you cannot see are suspended in the oil. Even oil formulations have metals in them that pass right through the filters. Usually we are more concerned with the erosion of these metals giving way to lose tolerances not necessarily their abrasiveness.
Have faith in the transmission they are built to handle these conditions.
