Driving style and trans problems
#16
I'd say my driving style is a 4 using the guide above. I don't think I've ever floored the accelerator in my car, and the thing rarely goes above 3000rpm. I'm looking more for quiet and easy transport as we tend to drive long distances. Travel speed on the highway is usually around 80mph.
In my case, I don't see this as a computer problem with the car. I've got the cold 3-4 problem, but also have the hot problem where 1-2 and 2-3 gear shifts occasionally have a big rpm slip and then slam the gear shifts. The hot problem is one that has been associated with the earlier 'dead' trans units for the early builds.

The thing I'm interested in finding out depends on how hard you accelerate, how high the shift points are, etc, not the average speed of travel. I assume that once the trans is in sixth gear, there's not much for it to learn, that the learning occurs with changes in load, rpm, speed, vacuum and throttle position.

I had no idea you car would slip 2 to 3.....that is what my former most often slipped in and once in a while the 3 to 4.
And it didn't seem to matter whether the car was cold or hot with the 2 to 3, it just did it when it darn well felt like doing it though it got somewhat more frequent as miles progressed and I got told never heard of one slipping 2 to 3, that is what showed up in recordings I did that sounded pitiful for the transmission and that is the gear that slipped with motorsports shop owner when he was riding in order to give his opinion on the diesel knocking of the engine.

Excellent. That would clear up a lot of paranoid here on the dreadful transmission flare. How many of you will notice a 500rpm spike before shift without watching the tachometer when you have your foot on the gas pedal? Unless there are some safety issues, I am not worried at all.

Sooner or later this fluid absence is going to cause other problems over time.

Based on the video of onsknht provided and my own experience, I doubt such flare is due to mechanical malfunctioning of some parts. More likely it is software related, and learning the driving style.
#24
No way is that software and not according to Lexus either, after all they are replacing parts that control trans fluid flow, the valve body does this and the (bearings) in them, according to techs, get impeded and do not allow proper fluid flow. If it were software it would do it each time the car was run through 3 to 4 or darn near and Lexus would not be spending the money to take apart a transmission, plus at least in my recordings you can hear it slip due to a lack of fluid type sound like the old AAMCO commercials.
#25
By the same token, if the mechanical failure is the cause as you described, Lexus could have fixed the problem long time ago. The fact is that blindly replacing parts (valves/transmissions/even the whole new car) did not seem to fix the problem.

If this were software our own poll on here would have 100 percent voting as having this flare or a good 95 percent voting they do with 5 percent just plain unaware. They are not cherry picking software for 1/4th the vehicles and then intentionally using a different kind of software for 3/4ths of vehicles.

thered,
The only reason I know this is because I spent a lot of time pondering whether or not I wanted my brand new car to have it's transmission taken apart as any new car owner would likely do and be very reluctant to experience it.
I past posted and said the techs are very patient, or were, they went over with me in exacting detail what was going wrong and why.
I decided that the TSIB would not work on my car because it supposedly only fixed the flow to gear shift 3 to 4 and would do nothing for gear shift 2 to 3 which, at least on my former car, was the most often but also 3 to 4.
If my newer car has this over time, I will wait until they do what they did with the Camry as posted on here, they changed transmission suppliers according to post, if accurate, as of latter part of October. No announcement about that for us yet, and until there is no matter whether it pans out I have this I will not allow the car to be worked on until they change suppliers or come out with another announcement of what THE final fix is for this.

Bob, if this transmission flare is indeed due to a part malfunctioning or design flaw, nobody could escape. Unless they find out something wrong with their design or off-specs from the parts made by the old supplier, changing suppliers seems like a shooting in the blind to me.

Sorry but I have to point out that operator variance is much larger than the product variance. I am more confident that majority of ES350s are made within the specs and tolerances and Lexus will not cherry pick any car to have a bad software. However, software can cherry pick the drivers, which can be very different, in terms their driving styles, not to mention their perceiption and tolerance for perfection. Machine is still far from as smart as we wish, especially when we expect the machine to learn from our driving habit.
