So I found this earlier... I'm going to call Lexus again tomorrow and talk to someone else. I talked to my sales person at Lexus Sacramento that's working with me to get me into a new 2013 GS350 F-Sport and He talked to the service techs on my behalf because I've been busy with meetings for the past few days.
They said that there was very little fluid inside the transmission and what was in it was extremely black and dirty and it over heated and THIS IS WHAT THEY THINK is the cause of failure as they haven't taken anything apart. But the thing is that I heard (don't know where I heard it), that the tranny doesn't need trans oil for 100k miles....so that's what I did...yeah I drove it hard and had fun with it because it's a performance car, and that's why I paid $60k for it, but if it says you don't have to do this for 100k...I never read anything that said...if you drive the car like a high performance car, you better do it at 25k...

These folks claiming there's some service at 100k have not looked at the guide for the IS F.

They are probably right.
When you were describing your original issue it sounded like you were low on trans fluid.
I bet that the trans had a ATF leak somewhere along the line (cooler lines, cooler, etc) and over time became lower and lower. Black/dark fluid usually means the fluid is toast due to overheating (and possible contamination of clutch pack material). If this car had a dipstick for the trans fluid, you would have been able to check it and see/smell the fluid.
Guys with big powered V8 auto trans cars with modified stall torque converter usually put in aftermarket in line coolers to keep the temps down. Heat is the main enemy of automatic transmissions.
Have you spoken with the Service Manager yet? Just remember be aggressive but polite.

Thanks for the info MisterSkiz...obviously I know nothing about automatic transmissions...I just know right now i don't like them...lol. My 5-speed manual tranny in my e30 3-series BMW is original @ 200k miles and still going and shifting perfectly fine. It would probably be even better if i changed some of the shifter bushings and linkages and what not.
Anyhow...new update for today.
Just got off the phone with Lexus and got to someone that's going to look into it. I should hear something today hopefully.....

There is nothing in the recommended service for the transmission except a leak check at 30k miles and every 30k after. If it leaked you didn't notice this when you did your own service, you're liable. If there is no leak and the fluid went bad on a LIFETIME filled transmission, then Lexus is to blame. There is no reason to expect you will ever need to service the transmission according to the recommended service guide.

They've also put this as a "priority" and they said i should hear back from someone today.

Well, I'll say it spooked me enough to pull the undercover off my gearbox and inspect for any signs of leakage. I also pulled an ATF sample and I sent it to Blackstone today for analysis.

Also, I guess you know why I drained & refilled mine at 50K back in Dec. 11'..
There is no good reason why this ATF WS tranny fluid shouldn't be changed more often, in my honest opinion..
(I have the same opinion for the 08'-09' Diff Fluid)

Another reason why I purchased the 120K mile extended warranty, to cover me well after the 6yr / 70k mile factory powertrain warranty.

If I was on a desert island and had to change the ATF fluid, I would just disconnect the cooler lines, have two buckets one with the exact amount of ATF fluid in it and the other with nothing in it and let the car idle and move the gear selector around to different gears.

Yeah, but that was only what was in the pan and trans right? You didn't pump out what is in the torque converter did you?

I hope you changed a lot more than what is in the picture. 4 quarts isn't even a half change. And yes, if I were going to do a change I would disconnect the cooler lines and put fresh in one side while the old came out the other. IIRC, there is more than 11 quarts in this unit from a dry fill.
Acknowledged.. It was a partial refresh of the fluid... (sort of a test if you know what I mean..
)I was chasing a shift flare..

SO....Lexus HQ called me today, but they have no answer for me until Monday....I'm gonna limp the car home. It seems perfectly fine driving on the freeway earlier for 40 miles in 8th gear...reverse is completely gone now and the car is on my sister's driveway, we're going to have to tow it out and I'm going to have to be very careful driving it home.....
Wish me luck. If Lexus does decide they're going to fix the transmission, I'm going to have it fixed and then sell the car. I hope they fix it........

Forget a harsh reverse...it's completely gone. Had to get towed out of my sisters drive way. Oh man...I really gotta think about where I'm driving now when I drive her home....

So if this is what is said inside the Scheduled Maintenace Log...I wonder how many more failed Transmissions Lexus is going to have after me. I could possibly be one of the highest mileage IS Fs out there as it has 87,500 miles roughly.
How am I suppose to know to replace the tranny oil when the Lexus manual says it's "not required"
Question for you guys that take your car to the dealership...if you're at 87k miles, and the service advisor says..."would you like to replace your transmission fluid...it's rated for 100k miles"...what would you say to them? I would assume most of us would probably say no and wait....
